[FRA Docket No. 87-2, Notice. No. 7]
RIN 2130-AB20
Automatic Train Control and Advanced Civil Speed Enforcement
System; Northeast Corridor Railroads
AGENCY: Federal Railroad Administration (FRA), Department of
Transportation (DOT).
ACTION: Final order of particular applicability.
-----------------------------------------------------------------------
SUMMARY: FRA issues an order of particular applicability (order)
applying to certain trains operating on the track controlled by the
National Railroad Passenger Corporation (Amtrak) on the Northeast
Corridor (NEC) between Washington, DC, and Boston, Massachusetts. The
order requires all trains operating between New Haven, Connecticut and
Boston (NEC-North End) to be controlled by locomotives equipped to
respond to a new advanced civil speed enforcement system (ACSES) in
addition to the automatic train control (ATC) system currently required
on the NEC. On the NEC between Washington, DC and New York, New York
(NEC-South End), where access to the high-speed track is prevented by
switches locked in the normal position and a parallel route to the
high-speed track is provided at crossovers from adjacent tracks, and
where no junctions providing direct access exist, ACSES-equipped trains
may operate to a maximum speed not to exceed 135 miles per hour (mph).
This order also contains performance standards for the cab signal/ATC
and ACSES systems on the NEC, and authorizes increases in certain
maximum authorized train speeds and safety requirements supporting
improved rail service.
DATES: This order becomes effective on August 21, 1998.

SUPPLEMENTARY INFORMATION:
Statutory Authority
FRA has both discrete and plenary legal authority to require all
trains operating on the NEC to be equipped with automatic train control
devices. FRA has broad legal authority to ``prescribe regulations, and
issue orders for every area of railroad safety * * *'' 49 U.S.C. 20103.
Section 20502 of Title 49, United States Code specifically provides
that ``[w]hen the Secretary of Transportation decides after an
investigation that it is necessary in the public interest, the
Secretary may order a railroad carrier to install * * * a signal system
that complies with the requirements of the Secretary.'' As originally
enacted and prior to formal codification, this provision referred to
``automatic train stop, train control, and/or other similar appliances,
methods, and systems intended to promote the safety of railroad
operation * * .'' This authority has been previously invoked to require
the installation of signal systems on 49 specific railroads and to
require all railroads desiring to operate at high speeds to install
signal systems of varying degrees of sophistication consonant with
those higher speeds.
Proceedings to Date
On November 20, 1997, FRA published a Proposed Order of Particular
Applicability (proposed order) that would require all trains operating
on the NEC-North End to be controlled by locomotives equipped to
respond to a new advanced civil speed enforcement system in addition to
the automatic train control system currently required on the NEC (62 FR
62097).
The proposed order called for written comments to be received by
January 20, 1998, and requests for a public hearing to be received by
December 22, 1997. On February 17, 1998, FRA held a public hearing at
the request of several commentators.
Background--Development of the NEC
Amtrak provides service over the NEC from Washington, DC, to
Boston, Massachusetts. Amtrak owns or dispatches most of the NEC, which
it shares with several commuter authorities and freight railroads.
Current speeds on the NEC-North End range up to 110 mph.
[[Page 39344]]
Amtrak is currently undertaking a major improvement project on the
NEC, with particular emphasis on completion of electrification,
installation of concrete ties and high-speed turnouts, elimination of
some remaining highway-rail crossings, and other modifications
concentrated between New Haven and Boston. These improvements are
designed to facilitate service utilizing high-speed trains (HSTs) at
speeds up to 150 mph. During 1999, Amtrak will begin taking delivery of
HSTs expected to qualify for operation through curves at higher levels
of unbalance (and thus higher speeds) than conventional trains.
Through this order, FRA ensures that planning for high-speed
service will not occur in isolation from measures that could reasonably
address increased traffic densities, and drive future innovative
technology.
Regulatory Approvals Required
In general, new signal and train control systems must comply with
FRA's Rules, Standards and Instructions Governing the Installation,
Inspection, Maintenance, and Repair of Signal and Train Control
Systems, Devices, and Appliances (49 CFR Part 236). FRA will implement
any exceptions on a case-by-case basis through the waiver process as
provided by 49 CFR Part 235. Train operations in excess of 110 mph must
be authorized by FRA after examination of pertinent safety
considerations in accordance with 49 CFR 213.9(c) (operating speed
limits). Metroliner service on the NEC is already conducted in
accordance with such an authorization.
In addition, NEC operations are subject to special requirements of
the Rail Safety Improvement Act of 1988, which mandated that all NEC
trains be equipped with ``automatic train control systems designed to
slow or stop a train in response to external signals.'' Sec. 9, Pub. L.
No. 100-342, implemented at 52 FR 44510 (Nov. 19, 1987), 53 FR 1433
(Jan. 19, 1988), and 53 FR 39834 (Oct. 12, 1988).
Summary of the Proposed Order
The proposed order would implement ACSES on the NEC-North End by
October 1, 1999, allowing Amtrak to increase its maximum operating
speed on this segment of the NEC from 105 mph to 150 mph. In addition
to Amtrak, the Connecticut Department of Transportation (ConnDOT),
Consolidated Rail Corporation (Conrail), the Massachusetts Bay
Transportation Authority (MBTA), and the Providence and Worcester
Railroad Company (P&W), which also operate on this territory, would be
required to equip their locomotives and cab cars with ACSES. (On July
23, 1998, the Surface Transportation Board is expected to approve the
division of Conrail between the Norfolk Southern Corporation (NS) and
the CSX Corporation (CSX); NS and CSX have yet to announce a date for
this division. NS and CSX, as successors to Conrail, will be subject to
this order to the extent that they operate on this segment of the NEC.)
FRA initially discussed the features and functions of ACSES with
the Northeast Corridor Safety Committee in September of 1994, and
Amtrak continued to brief the affected railroads as system development
proceeded. ACSES would enforce permanent speed restrictions caused by
curves, bridges and other factors, positive stops at interlocking home
signals and control points, work limits, and temporary slow orders,
through transponders similar to those used by European railroads.
Transponders are devices containing encoded information on such factors
as location and distance to the beginning of a speed restriction, type
of speed restriction, target speed, average grade, distance to the next
transponder, and message verification information. Transponders would
be installed at all approaches to interlockings within high speed
territory, including those where trains could mistakenly pass an
interlocking signal and encroach onto high speed track, as part of a
train control system which would be independent of the on-board cab
signal/automatic train control system, but would interface with it to
provide displays to train crews on factors such as civil speed
restrictions, trains located ahead, and interlocking conditions. A data
radio network would be used to download temporary movement
restrictions, among other functions.
Equipped rail vehicles would continuously transmit a signal which,
when received by a transponder, would cause the transponder to transmit
back its encoded message. Those messages, including speed and braking
conditions, would be received in the train's cab, interpreted by an on-
board computer, and passed along to the train's engineer for
appropriate action. If necessary, automatic braking would take place.
Amtrak would also expand its existing 4-aspect cab signal system,
which provides for ``restricted speed'', 30 mph, 45 mph, and the
maximum authorized speed for the equipment on which it is installed, to
a 9-aspect system, which provides for additional aspects of 60 mph, 80
mph, 100 mph, 125 mph, and 150 mph. The current 4-aspect system employs
a 100 Hz carrier frequency coded at the rates of 75, 120, and 180
pulses per minute; the 9-aspect system would employ an additional
carrier frequency of 250 Hz, and an additional code rate of 270 pulses
per minute. Amtrak developed this 9-aspect system to provide four
independent functions: (1) Operation of high-speed trainsets at a new
maximum speed of 150 mph; (2) higher speed diverging signal aspects,
upgrading the previous 45 mph diverging aspect; (3) an enforced 30 mph
diverging aspect; and (4) closer headways by adding three enforced
speeds between the existing 45 mph and 125 mph enforced speeds.
On the NEC-South End, the proposed order would require ACSES
wherever speeds exceeded 125 mph (the current maximum speed), with only
high speed trains equipped where crossovers could be locked to avoid
incursion. The proposed order contemplated, but did not require,
implementation of ACSES by all NEC users (except possibly the Metro-
North Commuter Railroad Company), including Amtrak, commuter railroads,
and freight carriers. To minimize the impact on users, ACSES would be
implemented incrementally as funding became available, so that
operational benefits could begin immediately as each portion of line
and each vehicle became equipped.
Summary of Modifications to the Proposed Order
In response to comments and technical changes in the proposed order
FRA has made modifications in this final order, the more significant of
which are highlighted below. The proposed order stated that comments
received after the close of the comment period would be considered to
the extent possible. Amtrak has continued to refine and adapt its
design specifications, as proposed in Amtrak's February 17, 1998
supplemental comments, May 8, 1998 letter (copies of both are in the
docket), and subsequent conversations with FRA (memorializations of
which are also in the docket). This order contains modifications
responsive to Amtrak's proposed design specification changes, which are
discussed below. A detailed analysis of the comments appears elsewhere
in this order.
Major Modifications
(1) Use of Temporary Transponders in Lieu of Loading Temporary
Restrictions
Under ACSES, temporary restrictions flow directly from the computer
assisted dispatch center into the data radio channel and thus into the
on-board computer, virtually eliminating errors in transmission or
recordation and
[[Page 39345]]
ensuring that information is acted upon. Were train crew members to
enter this data, they could make errors and then be tempted to rely on
the ``system'' to provide the required speed reductions on the cab
display in lieu of relying on a paper copy.
In a letter dated May 8, 1998, Amtrak requested permission to use
temporary transponders (placed in the gage of the rail) as an
alternative to inputting temporary restrictions by direct data radio
link into the on-board computer. Typically, Amtrak would place these at
locations approaching work zones and other slow order zones. Although
FRA considers temporary transponder placement acceptable for last
minute slow orders in emergencies where reliable communication to the
en route train cannot be assured, FRA believes the better practice is
to require temporary restrictions to be automatically loaded into the
on-board computer. FRA will allow Amtrak to use temporary transponders
as an alternative routinely for the first 12 months after
implementation of this order in order to ease transition to this new
system. After this period, temporary transponders may be deployed only
on an emergency basis unless they are being used as an additional
safety measure.
(2) Availability of Data Radio Release at Interlockings
FRA proposed to require, and Amtrak expects to provide, a
capability that would automatically permit movement of a train past an
interlocking signal displaying a stop and proceed or restricting aspect
without the necessity of the engineer leaving his or her normal
position in the cab to press a release button. To ensure that this
capability is in place and fully operational, FRA requires data radio
transmitters to be located at interlockings and interfaced with
interlocking controllers not less than 12 months following activation
(cut in) of ACSES.
Elimination of recurring acknowledgment. Amtrak's original plan
included a recurring 15 second audible alarm and a 20 second
acknowledgment while operating at restricted speed. In a May 8, 1998
letter, Amtrak proposed to modify this ATC feature, disliked by many
locomotive engineers. The modified feature would sound a warning
immediately and require acknowledgment within 5 seconds whenever
initial movement is detected while the cab signal displays
``restricting,'' in order to prevent a penalty brake application. (FRA
assumes that the one-time acknowledgment would be required on downgrade
to restricting as well.) Through the use of data radio at the
interlockings, this feature would automatically permit movement of a
train past an interlocking signal displaying a stop and proceed or
restricting aspect without the necessity of the engineer leaving his or
her normal position in the cab to press a release button. FRA has
agreed to this proposed feature, which Amtrak suggests would be
particularly useful when a train is starting from a stop at a station
close to an interlocking home signal.
(3) Speeds Over Highway-Rail Crossings
In the proposed order, FRA suggested a speed limit over any
highway-rail crossing of 80 mph, for the following reasons:
Speeds over highway-rail crossings will be limited to 80 mph,
the maximum speed planned under the NEC program until very recently.
This limit is lower than the 110 mph cap included in current
guidelines for high-speed corridors (absent barrier and presence
detection systems tied into the signal system), because of the
density of NEC operations and the increased possibility that a
collision with a motor vehicle might cause a secondary collision
between trains operating at very high combined closing speeds. FRA
reserves the right to allow higher speeds over individual highway-
rail crossings after demonstration by Amtrak that appropriate safety
measures have been implemented.
Dense operations on the NEC-North End present special safety
concerns, particularly since both intercity and commuter trains will be
operating with improved acceleration as electric locomotives and HSTs
are deployed--driving up average speeds. This is a two-track railroad
throughout its length, with 13 crossings between New Haven and Boston.
Although the crossings in question are generally low-volume, most are
subject to the movement of large vehicles such as flatbed trucks
carrying boats, garbage trucks, fire trucks, and other substantial
vehicles known to be capable of derailing a train. The likelihood of a
derailment may increase to some extent, even in the case of collision
with a relatively light vehicle, if the crossing in question is on a
curve and Amtrak is successful in qualifying its HSTs for levels of
unbalance up to 9 inches, as provided in a previously issued waiver.
Therefore, in this order, FRA sets a maximum operating speed of 80
mph over any highway-rail crossing where only conventional warning
systems are in place, and a maximum operating speed of 95 mph where 4-
quadrant gates and presence detection are provided and tied into the
signal system. FRA also requires Amtrak to submit for approval plans
for site-specific improvements with timetables for each of the 13
crossings on the NEC-North End by January 1, 1999.
(4) Signal and Train Control Enhancements
Providing signalization for high-speed intercity service requires
implementation of an enhanced cab signal/speed control system that
allows for higher train speeds while providing sufficient gradations of
intermediate speeds to allow efficient movement of other scheduled
trains operating in the conventional speed range. Reasonable
interoperability of existing and up-graded on-board equipment is also
necessary to allow for the continued use of existing on-board equipment
at conventional speeds only.
9-Aspect Cab Signal System. The cab signal/ATC portion of the
upgraded system will employ two carrier frequencies, 100 Hz, compatible
with existing equipment, and 250 Hz. Both frequencies will be coded at
standard rates of 75, 120, 180, and 270 cycles per minute. Upgraded
equipment will be able to take advantage of the 150 mph code rate for
maximum authorized speed, the 80 mph code rate for high speed diverging
moves, and separate 45/40 and 30 mph speed commands for limited and
medium speed turnouts.
ACSES. In contrast to the modified cab signal system, ACSES will
provide new safety functions that, with limited exceptions, are not
currently provided. For purposes of civil speed control, permanent
wayside transponders will be placed in sets (normally two to a set) at
convenient, accessible locations in the center of the track approaching
speed restriction zones. Most of these transponders will be passive
devices requiring no energy source other than that transmitted from a
passing train. Each permanent transponder set will contain encoded
information about speed restrictions ahead, including: (i) The distance
to the beginning of the speed restriction; (ii) The target speed; (iii)
The type of speed restriction; (iv) The average grade between the
location where the speed reduction must begin and the location where
the reduced speed must be reached; (v) The distance to the next
permanent transponder set location; and (vi) Necessary sync and check
bytes to allow for message verification.
Improvements that Amtrak will gain with the new systems are:
Train speeds of up to 150 mph;
A high speed diverging aspect (80 mph);
The efficient handling of both high speed and conventional
trains;
[[Page 39346]]
New intermediate speeds between 45 mph and 150 mph;
The capability for headway improvement in congested
commuter areas; and
Practical staging from present wayside and on-board
equipment.
Commuter and freight railroads will both benefit from enhanced
safety of Amtrak operations, given the common operating environment,
since Amtrak's implementation of the 9-aspect cab signal system will
provide increased flexibility to schedule high speed intercity service
in a way that does not conflict with commuter operations. In addition,
as ACSES is implemented on commuter and freight trains, the safety of
those operations will be enhanced by ensuring that those trains do not
pass absolute stop signals or operate at excessive speed approaching
stations or bridges. To the extent equipment design permits, commuter
operators may take advantage of higher speeds on curves without
diminished safety margins with the new flexibility for operation at
higher cant deficiencies in FRA's revised Track Safety Standards (63 FR
33992; June 22, 1998).
Amtrak will phase-in installation in order to obtain the maximum
benefit from the positive stop and civil speed enforcement system prior
to its installation on the Amtrak-dispatched portions of the NEC. The
initial installations will protect entry to and operations along the
high speed territory. During this initial phase, transponders will not
be installed on non-high speed tracks where flanking protection
protects against possible encroachment into adjacent high speed tracks.
The transponder system will be extended to the balance of the NEC after
all installations are in place on high speed tracks and on adjacent
tracks where flanking protection does not exist. (This description in
no way pre-decides the issue of whether trains of other operators on
other portions of the NEC will be required to be equipped.)
(5) Nighttime Operations
As an interim measure to allow for gradual equipping of a
railroad's locomotive fleet, FRA had proposed to allow unequipped
freight operations to enter the NEC-North End during low-volume night
hours. After considering the comments (discussed in more detail below),
FRA is not adopting this proposal for two reasons. First, train delays
could cause fast trains to invade the window or unequipped trains to
fail to clear the window in time. Second, Amtrak expects to conduct
most production track work at night, and unequipped trains would not be
prevented from entering work zones or passing work groups at excessive
speed, resulting in reduced safety benefits. Instead of the proposed
time window, FRA will handle any exceptions to this order through
waivers or spot amendments to the order.
Proceedings on This Order
FRA sought public comment on the proposed order and related
matters, including any authorization that may be required for Amtrak to
implement a modified cab signal system on the NEC. FRA has placed in
the docket of this proceeding copies of Amtrak's program description
for the ACSES system, proposed operating rules for use in conjunction
with the system, and other related information, including current
Amtrak projections for operating speeds over highway-rail crossings on
the NEC-North End. FRA has reviewed the comments and hearing testimony,
which have been extremely helpful in resolving these issues.
The following parties testified at the February 17 hearing: The
American Public Transit Association (APTA), the Brotherhood of
Locomotive Engineers-American Train Dispatchers Division (BLE-ATTD),
ConnDOT, Conrail, MBTA, P&W, and Southeastern Pennsylvania
Transportation Authority (SEPTA).
In addition, written comments were submitted by the following:
Amtrak, APTA, Brotherhood of Locomotive Engineers (BLE), ConnDOT,
Conrail, Long Island Railroad (LIRR), MBTA, Metro-North Commuter
Railroad Company (Metro-North), National Transportation Safety Board
(NTSB or Board), P&W, Representative Patrick J. Kennedy, Senator Edward
M. Kennedy, Senator Jack Reed, and SEPTA.
The following also submitted comments in support of P&W's concerns:
Arnold Lumber Co., Atlantic Wire, BB&S Treated Lumber of New
England, Colfax Inc., Dominion Rebar, Fortune Plastics Inc., The
Narragansett Bay Commission, Seaview Transportation Company, Inc.,
Ring's End, and Unilever.
While many commentators spoke or wrote on more than one issue, and
while most of the comments supported the position(s) of at least one
other commentator, the issues themselves were grouped around a few key
points, which are discussed below.
General Issues
(1) Scope of Order
Several commentators stated that the proposed order did not define
its applicability clearly. SEPTA commented that the proposed order did
not specify its applicability south of New Haven, and APTA also
requested additional clarification on the order's scope and
applicability on the NEC-South End.
As proposed by Amtrak, implementation of the ACSES system would
impact all NEC users including Amtrak, commuter railroads, and freight
carriers, with the exception of the NEC segment operated by the New
York Metropolitan Transportation Authority (MTA) and Metro-North. ACSES
would be implemented incrementally as funding becomes available, so
that operational benefits would begin immediately as each portion of
line and each vehicle becomes equipped.
At this time, FRA mandates that all trains operating on the NEC-
North End be equipped with operative on-board equipment that responds
to ACSES, as proposed. This order also authorizes higher speeds for
such equipped trains on high-speed tracks on the NEC-South End, but
other trains utilizing those tracks or adjacent tracks are not required
to be equipped. FRA will continue to study the reliability and safety
benefits of ACSES as implementation on the NEC-North End is completed,
and may later propose to require ACSES on the rest of the NEC as
traffic densities increase.
ConnDOT commented that the proposed order contained errors
regarding the ownership of the New Haven, Connecticut-New Rochelle, New
York section of NEC track. FRA agrees that Metro-North does not own any
segment of the NEC, that ConnDOT owns the track between New Haven and
the Connecticut-New York border, and that MTA owns the track between
that border and New Rochelle. Thus, this order does not address the
territory owned by MTA between the Connecticut/New York State line and
New Rochelle, or the area owned by ConnDOT between the Connecticut/New
York State line and New Haven, both of which are dispatched by Metro-
North.
(2) Implementation Schedule
Several commentators felt that the proposed implementation date of
October 1, 1999 did not provide sufficient time for financing and
equipment installation. MBTA recommended a longer time period to
provide sufficient time for responsible design, engineering and
prototyping. MBTA also commented that modifications to safety critical
systems should not be made on a high speed schedule, and that the
proposed
[[Page 39347]]
implementation date was unrealistic and would impose premium costs.
Conrail commented that the proposed order failed to indicate any target
dates or deadlines, which are necessary to determine the migration
plan. ConnDOT requested to be removed from the scope and applicability
of the order unless full funding is provided and compliance is delayed
until 2001. P&W commented that compliance with the proposed October
1999 implementation deadline would be impossible unless Amtrak supplied
substitute power and assistance in accomplishing the required
retrofits.
The NTSB, however, while recognizing the need for an interim period
to allow equipping of locomotives, strongly urged that FRA set a fixed
time for compliance.
FRA recognizes that completion of all steps required to implement
ACSES by October 1, 1999 depends upon Amtrak rigorously adhering to a
well-crafted timetable that allows adequate time for installation of
on-board units on all affected operators without depriving those
operators of equipment necessary to provide normal service. This should
be achievable by combining required inspections and tests with the
installation process, provided production runs of on-board equipment
commence in a timely way and deliveries are sequenced properly.
However, thus far Amtrak has provided FRA with a very limited amount of
information concerning its test program and key milestones.
Accordingly, this order requires early delivery of a very specific
timetable for initial testing and qualification, for installation of
on-board equipment on Amtrak, ConnDOT, MBTA, and P&W locomotives, and
for final acceptance testing for the system. FRA will evaluate this
timetable for reasonableness. To the extent the timetable indicates
unacceptable impacts on third parties, or to the extent milestones in
this schedule slip, FRA will defer the implementation date as
necessary. FRA will keep open the docket of this proceeding to receive
any petitions for adjustment of the compliance date.
(3) Financial Responsibility
Commentators expressed the most concern about the overall cost of
ACSES, and the related issue of who would bear the cost of equipping
non-Amtrak equipment. In addition to the implementation costs of
locomotive retrofitting, passive transponders and other related
expenses, commentators were concerned about maintenance, equipment
down-time, schedule disruptions, and life-cycle expense. Many
commentators submitted preliminary estimates of their anticipated
costs. MBTA, for instance, has already budgeted the estimated $11
million cost of retrofitting its locomotives with the 9-aspect system
into its current locomotive procurement and planned overhaul.
P&W commented that the final order should require the High Speed
Passenger Project (Project) to assume the costs of retrofitting
locomotives since ACSES is a fundamental component of the Project. P&W
indicated that as a small private sector freight operator, it is not
subsidized (unlike Amtrak and commuter rail operations), and would not
stay competitive with trucking operations on the I-95 corridor if it
passed ACSES implementation costs onto its customers. Although P&W
objected to paying for ACSES implementation to realize the proposed 150
mph speeds on the NEC-North End, P&W pledged to work with Amtrak to
develop an implementation schedule once a retrofit design is available
for review.
Senators Edward M. Kennedy and Jack Reed, and Representative
Patrick J. Kennedy wrote in support of P&W's views. In his comments,
Senator Kennedy reiterated his support for the Project, and agreed with
P&W's recommendation that the Project assume P&W's implementation
costs.
MBTA also objected to the proposed order, commenting that it would
impose unfunded mandates on state authorities. MBTA also recommended
that the proposed order be amended to require funding by the Project,
and, in addition, to hold MBTA harmless from right of way construction
costs.
ConnDOT commented that FRA and Amtrak should provide full funding
for ACSES implementation, since this investment in equipment and
infrastructure is necessitated by Amtrak's new HST service. ConnDOT
indicated that it does not have access to funding required to comply
with the order on its Shore Line East operation. Moreover, the tenuous
viability of Shore Line East commuter service and the concurrent
funding needed for double-sided high speed platforms could force this
line of commuter rail service to close. ConnDOT requested that FRA
pledge to provide full funding for any mandated conversion to ACSES.
SEPTA commented that NEC commuter railroads have undergone a number
of mandatory retrofits in recent years (e.g., speed control, event
recorders, ditch lights, and emergency door access), and expect
additional required retrofits even though separate funding has never
been provided for this work. Since SEPTA capital is limited, requiring
commuter railroads to fund systems such as ACSES would force tradeoffs
with other safety improvements. SEPTA proposed that the proposed
modifications and civil speed enforcement system be funded by Amtrak,
as the beneficiary of these proposed requirements.
Conrail commented that the proposed order's purpose is to enable
higher speed passenger operations through improved train control
systems. Conrail, however, has already invested in the Locomotive Speed
Limiter (LSL) system, to provide train control compatible with the NEC
cab signal system. While Conrail has a vested interest in improving
safety and reducing risk, the additional risks caused by higher speed
passenger operations are being introduced by other parties and should
not be borne by Conrail. Like other commentators, Conrail urged FRA to
structure the final order to provide relief from the cost burden,
arguing that ACSES will provide no quantifiable benefits beyond
Conrail's current LSL system.
Metro-North requested that its territory be excluded from the final
order, stating that it will not operate at high speeds since the
catenary and signal systems on the territory between New Rochelle and
New Haven are designed for a maximum of 100 mph.
The NTSB, on the other hand, strongly supported the proposed order,
since Positive Train Separation (PTS) is one of the Board's ``Most
Wanted'' safety measures. The Board recommended that FRA require
implementation of PTS for ``all trains where commuter and intercity
passenger railroads operate,'' including the South End.
Allocation of financial responsibility. FRA appreciates that
resolving the issue of which organizations bear the ultimate financial
responsibility for this safety system is not a simple or
straightforward matter. The Project with which this safety enhancement
is associated has been aggressively advocated by the Coalition of
Northeastern Governors for many years and supported by most members of
the northeast congressional delegations. While the Project has national
significance, a large share of the benefits will accrue to the region,
including potential avoidance of major costs associated with
improvement of aviation and highway facilities. As a result of careful
planning and aggressive advocacy, the region will enjoy many related
improvements to its transportation infrastructure, including the
opening of rail access for double
[[Page 39348]]
stack intermodal service to the site of the former U.S. Navy facilities
at Quonset Point and Davisville, Rhode Island, at a cost to the Federal
taxpayer estimated at $55 million.
Amtrak has recognized its stake in this Project by budgeting 100%
of wayside costs of ACSES, even though much of the territory involved
is actually owned by other public authorities. In addition, Amtrak will
bear the cost for equipping its own trains, high-speed and
conventional.
Since issuance of the notice of proposed order, Amtrak has
communicated with ConnDOT, MBTA, and P&W regarding the logistics of
this Project. Although FRA has not been privy to the details of these
conversations, copies of letters provided for the docket of this
rulemaking affirm that Amtrak has secured an option with its vendor for
a sufficient number of on-board equipment sets to the benefit of these
other railroads. Amtrak has offered to complete installation at a cost
of $40,000, split between approximately $27,000 for the equipment and
$13,000 for installation. Amtrak has also offered to assist these
railroads by supporting their ``efforts to find a source of funding.''
FRA is concerned that parties to the rulemaking may have hesitated
to make reasonable financial arrangements for this work with the
anticipation that FRA would spare them the necessity by allocating that
responsibility in this final order. From the point of view of staging
the work, FRA has confidence that Amtrak will ensure interim financing
to complete equipping of ConnDOT, MBTA, and P&W locomotives. Conrail
and its successors (NS and CSX) are major Class I railroads fully
capable of handling their own financing. The remaining issue is who
will bear the ultimate financial burden, and the considerations
pertaining to this question are far more complex than could be
developed within the scope of this proceeding.
It seems reasonable to expect that Conrail or its successors will
shoulder the cost of this safety improvement and equip as many
locomotives as may be appropriate for optimum power utilization over
its system. FRA has provided funding under a cooperative agreement with
Conrail, NS and CSX for development of an on-board platform capable of
providing interoperability among various train control systems,
including ACS, ATC, and ACSES. This innovation may help hold down the
cost of ACSES compliance.
FRA has carefully considered P&W's comments regarding its role in
this safety improvement. FRA appreciates P&W's willingness to cooperate
and its concerns regarding the timing of the necessary retrofits
(further addressed below), and accepts P&W's representation that at
least 22 locomotives will need to be equipped with ACSES and that
nighttime operation is not a viable option. However, FRA had not
identified from P&W's submission a basis for becoming more directly
involved in deciding the matter of financial responsibility.
P&W operates on the NEC largely as a result of an expedited
supplemental transaction effected under section 1155 of the Northeast
Rail Service Act of 1981 (NERSA) (45 U.S.C. 745). Pursuant to that
statute, and under an order of the Special Court established by the
Regional Rail Reorganization Act of 1973, Conrail was compelled to
surrender certain properties and service rights to a successor railroad
that would commit to providing at least 4 years of service on the
properties transferred. P&W aggressively pursued that opportunity, with
the full knowledge that public planning from the 1960's forward had
focused on dramatic passenger service improvements on the NEC between
New York and Boston. As recently as the past year, P&W has sought to
extend its service rights farther west into Connecticut based upon
P&W's claim that the proposed acquisition of Conrail by NS and CSX
constitutes a termination of Conrail's residual franchise and
activation of rights P&W enjoys under the Special Court's order. As
noted above, as an adjunct to the current improvement project, P&W will
be the beneficiary of construction of a third track on the NEC between
Davisville and ``Boston Switch'' that will provide the new doublestack
access that otherwise would not exist.
MBTA and ConnDOT are also realizing considerable benefits from the
improvement project. MBTA is already implementing plans to utilize
electric locomotives which will provide improved accelerations, reduced
trip times and reduced emission of polluting gases and particulates.
ConnDOT and MBTA benefit substantially from Amtrak's substantial
investments in the track structure associated with high-speed
operations.
All of the operators over the affected territory will enjoy
benefits from ACSES, such as the following:
(1) Reduction of risk related to collisions at junctions. This
feature may help avoid a collision with a high-speed or conventional
passenger train that could result in massive liability.
(2) Reduction of the risk of derailment on curves and secondary
collisions following such derailments. Although principally a benefit
to high-speed trains, this feature may benefit other passenger
operators that wish to take advantage of higher levels of unbalance to
achieve improved trip times (which, without ACSES, might be imprudent).
Even freight operators may benefit under conditions where cab signals
must be cut out due to en route malfunction.
(3) Reduction of risk related to incidents involving roadway
workers and their equipment. This benefit should accrue to all
operators very nearly in direct proportion to the number of trains they
operate.
(4) Improved scheduling and execution of roadway inspections and
maintenance associated with the ability to load temporary movement
restrictions into the on-board units of trains en route through data
radio facilities along the route. This benefit, which may be realized
over a period of several years, should help hold down costs and
increase efficiency for all operators. If the data radio network is
fully exploited, dispatching may also be enhanced through access to
real-time train location information.
FRA is aware of contrary arguments for allocation of financial
responsibility based upon the institution of high-speed service and the
timing of requirements for compliance. These arguments may be worthy of
consideration within the full context of the commercial relationships
involved, including existing arrangements for allocating costs of
operation over the affected NEC segments, contractual arrangements for
operation of commuter service, and any relationships established for
executing the obligations imposed by this order. Forums such as the
Surface Transportation Board, arbitration panels referenced in existing
agreements, and courts of appropriate jurisdiction may have a role in
determining the ultimate allocation of financial responsibility for
implementation of ACSES, should the parties fail to come to mutually
acceptable accommodations.
In summary, the arguments related to financial responsibility are
complex; and various forums are available to resolve them. It is
neither necessary nor appropriate for those determinations to be made
in this order, and FRA does not intend by this order to govern the
ultimate allocation of financial responsibility for equipping non-
Amtrak locomotives and cab cars. However, FRA does require that trains
be equipped within a fixed time frame as a condition of operating over
the subject territory. This approach is consistent with prior orders of
the Interstate
[[Page 39349]]
Commerce Commission and FRA actions pertaining to train control,
including prior train control orders for the NEC, which have generally
required that all trains operating in a designated territory be
equipped, without regard to ownership.
(4) ACSES and the Railroad Safety Advisory Committee
In 1996, FRA established the Railroad Safety Advisory Committee
(RSAC or the Committee) to implement a more consensual approach to
rulemaking. RSAC is comprised of 48 representatives from 27 member
organizations, including railroads, labor groups, equipment
manufacturers, state government groups, public associations, and two
associate non-voting representatives from Canada and Mexico. To address
specific tasks, RSAC formed working groups, comprised of knowledgeable
persons from the organizations represented on RSAC. Among the current
working groups is a group on positive train control (PTC), which was
tasked on September 30, 1997, and met for the first time in November.
This group is considering three tasks related to development of
performance standards for new train control systems, evaluation of
costs and benefits of PTC, and consideration of issues related to
implement.
Both APTA and Conrail commented that the proposed order contained
no input from the PTC working group. Since the final order would define
and implement PTC on the NEC-North End, both recommended that FRA not
issue the final order until the PTC working group has completed its
task. Conrail also commented that the proposed order would impose
similar costs for functions that duplicate PTC.
Although FRA and Amtrak have briefed the RSAC PTC Working Group on
ACSES and the proposed order in this proceeding, FRA has not tasked the
PTC Working Group with development of this order, which pertains to a
specific territory already equipped with ACS and ATC (in contrast to
most of remainder of the general rail system). ACSES is intended to
supplement the existing train control system on the NEC, completing
positive train control functions in a manner that is cost effective and
capable of execution within the time period necessary to support
enhanced service associated with electrification and the delivery of
new HSTs.
Though not required to do so, FRA utilized the Northeast Corridor
Safety Committee to develop issues related to ACSES at a meeting in
September of 1994, and Amtrak has proceeded since that time to bring
ACSES to a high state of maturity. The ACSES system is specifically
designed to support dense passenger operations at up to 150 mph. Its
architecture provides a particularly suitable approach for NEC and
related operations (as illustrated by New Jersey Transit's use of a
similar approach to rapidly implement a positive stop system on its own
lines).
ACSES uses components and strategies already extensively employed
in European train control and other applications. ACSES will be applied
to equipment that--with the exception of a small number of freight
locomotives on the NEC at any given time--is largely dedicated to NEC
operations.
By contrast, the RSAC PTC Working Group is considering the
potential for train control systems that would be applied principally
in non-electrified territory, over most of which freight operations
predominate and shared power arrangements permit locomotives to range
extensively. For most of the National rail system, there is presently
no ACS/ATC infrastructure on the wayside, and many locomotives are not
equipped with responsive apparatus. PTC systems for most of the general
rail system will likely utilize a much different architecture that the
combination of ACS, ATC and ACSES provided in this and related orders.
In concert with a train control project sponsored by the State of
Illinois and the FRA, the Association of American Railroads'
Transportation Technology Center Inc. is just now commencing work on
criteria for interoperability of such systems that is expected to
extend past the actual cut-in date for ACSES. The extent to which PTC
systems designed for general applications may be capable of supporting
train speeds above 110 or 125 miles per hour is not currently known,
and widespread deployment of these systems will not be possible until
test and demonstration projects now underway reach fruition.
In short, awaiting the results of the RSAC PTC Working Group would
defer important safety enhancements for territory where the chosen
strategy is ready to implement and particularly appropriate. The PTC
Working Group was formed to accelerate movement toward implementation
of PTC safety functions, not to impede it. FRA looks forward to
institution of high-speed service on the NEC-North End late next year,
and implementation of ACSES is necessary to ensure the safety of that
service within the context of dense passenger and freight operations.
(5) Nighttime operations
P&W commented that it would not be feasible to limit its train
operations to night time, the window within which the order proposed to
permit non-equipped trains to run on the NEC, since nighttime switching
service would result in a dramatic increase in costs, cause operational
disruptions for P&W customers, disrupt neighborhoods, and raise serious
safety issues. Conrail commented that while the order was unclear as to
whether Conrail would be permitted to operate non-equipped trains using
time separation from high speed passenger schedules, mandatory time
separation is not an acceptable business solution since Conrail already
operates during lightly scheduled passenger periods for efficiency.
Although the proposed order properly anticipates potential increases in
operation by Conrail or its successors, Conrail commented that
operations would be adversely impacted if time separations are mandated
for trains not equipped with ACSES.
As discussed above, after considering the comments, FRA is not
allowing a window within which non-equipped trains could operate during
early morning hours when high-speed trains are not on the territory.
Any exceptions will be handled through waivers or spot amendments to
the order.
Technical Issues
(1) Flanking Protection
BLE-ATTD asked for an interpretation of the term ``flanking
protection,'' and a description of how such protection would work. BLE-
ATTD also requested clarification as to how flanking protection would
work on the NEC-South End, on whether electric lock derails would be
used instead of flanking protection in two-track areas, and on who
would enter information into the mobile communication package.
Flanking protection is inherent in interlockings where there are
parallel tracks. On a four track railroad, for example, with high speed
middle tracks, lower speed outer tracks, and crossovers across all four
tracks, a train could not overrun a signal on an adjacent track and
encroach onto the path of a high speed train if the signal was lined up
for the high speed track straight down one of the middle tracks.
Flanking protection is not a new concept designed to work with ACSES
since it is already in place at interlockings where there is a parallel
route to the track being protected in the event of a signal overrun.
[[Page 39350]]
(2) Interoperability With Existing Systems
Several commentators were concerned about the impact of the new
ACSES system on current signal systems. Conrail questioned whether its
existing 4-aspect system would be compatible with the new 9-aspect
system, and whether ACSES would interfere with an ongoing Conrail/CSX/
NS project to develop an on-board platform to support multiple system
configurations. LIRR also questioned how ACSES would interfere with
existing ATC systems, and how the proposed order would impact those
railroads sharing track with Amtrak at speeds over 100 mph. APTA wanted
to review Amtrak's equipment specifications because of concerns about
the reliability and maintainability of untested equipment. APTA also
questioned ACSES' impact on existing ATC systems and commuter rail
outside the NEC. ConnDOT questioned the benefits of the proposed
system, and SEPTA expressed concern about how ACSES would affect
operations outside of the areas where wayside equipment is installed.
In Amtrak's proposed system, the brake and propulsion interface
between the ACSES and the locomotive would be similar to that utilized
in conventional cab signal/ATC systems. The interface would be separate
and distinct from the interface used by the cab signal/ATC system. The
failure of either the cab signal/ATC system or the ACSES would not
prevent the remaining functioning system from performing its intended
operation and displaying the proper on-board aspect. Both the signal
speed and the civil speed would be displayed with the lower of the two
speeds to be enforced.
FRA questioned the need or prudence of displaying both speeds and
requested comment on the appropriate means of displaying system
information to the locomotive engineer. Amtrak submitted the only
response on this issue. In a January 16, 1998 letter, Amtrak clarified
that the 9-Aspect Cab Signal/ATC system and the ACSES system are
independent systems that share a common display. The 9-ACS/ATC system
will continuously display the ``signal'' speed, dependent upon routes
opening up in front of the approaching train, and supported by eight
simple codes supplied continuously to the train through the rails. The
ACSES system, on the other hand, will enforce the track (civil) maximum
authorized speeds, supported by more complex codes received at
intermittent intervals from transponders located along the track
structure. The ``signal'' speed is actually part of the cab signal
aspect (e.g., ``CLEAR 150,'' ``CLEAR 125,'' ``CAB SPEED 80''), with
discrete aspects displayed in accordance with Part 236. The ``track''
speed will be carefully coordinated with the cab signal aspect, and
highlighted to clearly indicate which speed (always the lower) governs.
The lower speed will always be enforced. Thus, merging the two digital
``speed'' displays into one ``window'' would seriously complicate and
undermine the stand-alone capability of each system if the other should
fail, and would compromise the viability of the redundancy or ``back-
up'' capability envisioned for the total system.
(3) 60 mph Turnouts
Amtrak had proposed, as an interim measure, to install #26.5
straight-frog turnouts at those crossovers where there is insufficient
space to install the #32.7 turnouts needed for diverging moves at 80
mph. Since these #26.5 straight-frog turnouts could be used only for
diverging moves at 60 mph, ACSES passive transponder sets approaching
such locations would enforce a 60 mph civil speed restriction for all
routes through the interlocking where the # 26.5 turnout is located.
The 60 mph speed restriction would also be backed up by a site specific
instruction and an appropriate reflectorized sign on the distant
signal.
NTSB, however, remained concerned about how this system would work
when a train's on-board ACSES system was cut out, since the train would
then be unable to read the speed restrictions transmitted by the
temporary transponders. In a June 4, 1998 conversation with FRA
(memorialized in the docket), Amtrak stated that implementation of this
proposed interim system was unlikely. While long-range planning may
eventually require the installation of some 60 mph turnouts on the NEC,
none are currently planned for the territory between New Haven and
Boston. If such installations become necessary in the future, Amtrak
intends to restrict passenger train speeds at these locations to 45
mph, or request a site specific waiver for each location.
Section-by-Section Analysis
The section-by-section analysis below discusses the modifications
made from the proposed order in response to comments or technical
considerations. Each section of the final order is printed in small
type and followed by its analysis. The final order is reprinted in its
entirety at the end of this preamble discussion.
Effective Date
As discussed above, this order becomes effective on the date
proposed, October 1, 1999. FRA will defer the implementation date if
necessary and keep open the docket of this proceeding to receive any
petitions for adjustment of the compliance date.
Scope and Applicability
This order supplements existing regulations at 49 CFR Part 236
and existing orders for automatic train control on track controlled
by the National Railroad Passenger Corporation (Amtrak) on the
Northeast Corridor (NEC) between Washington, D. C., and Boston,
Massachusetts. This order applies in territory where Amtrak has
installed wayside elements of the Advanced Civil Speed Enforcement
System (ACSES), permitting high-speed operations under the
conditions set forth below.
All railroads operating on high-speed tracks in such equipped
territory between Boston, Massachusetts and New Haven, Connecticut
(NEC-North End), or on tracks providing access to such high-speed
tracks, shall be subject to this order, including the following
entities operating or contracting for the operation of rail
service--
Amtrak;
Connecticut Department of Transportation;
Consolidated Rail Corporation and its successors;
Massachusetts Bay Transportation Authority; and
Providence and Worcester Railroad Company.
The requirement that all trains be equipped with operative on-
board ACSES applies as specified in paragraph (2) from milepost 73.2
at New Haven, Connecticut, to South Station, Boston, Massachusetts,
but applies only to high-speed trains operating on NEC high-speed
tracks between Washington, D.C., and New York, New York (NEC-South
End), as set forth in paragraph 9(b).
Explanation and Analysis. Amtrak has undertaken the planning and
installation of the ACSES as part of its capital program for intercity
service on the NEC, consistent with legislation providing for improved
rail service in the region. This order requires all carriers operating
in ACSES territory to equip their controlling locomotives with
operative on-board equipment, consisting of a transponder scanner, an
on-board computer, a display unit for the locomotive engineer, and
appropriate interface with the cab signal/train control apparatus. The
final order clarifies that trains other than HSTs must be equipped on
the NEC-North End but not on the NEC-South End.
Over time, the ACSES system may be completed and used by all
operators throughout the NEC for routes where speeds exceed 110 mph on
any segment, enhancing safety throughout the NEC.
[[Page 39351]]
For example, New Jersey Transit Rail Operations (NJT) intends to equip
its controlling locomotives with an Advanced Speed Enforcement System
(ASES), deriving safety advantages both on the NEC and on certain of
its lines where the ASES system can be used as an intermittent train
stop system. As Amtrak, NEC-North End operators and NJT demonstrate the
benefits and reliability of the system, progress toward universal
upgrading of the NEC signal and train control system will be fostered.
At a later date, FRA may propose to amend this order to require more
extensive use of this new safety technology, as determined by increases
in traffic and types of equipment used on the NEC.
Definitions. Unless otherwise provided terms used in this order
have the same definitions contained in Part 236. For purposes of
this order--
ACSES means a transponder based system that operates independent
of the cab signal system, and provides enforcement of permanent
speed restrictions, temporary speed restrictions, and stop signals
at interlockings.
High-speed train means a train operating in excess of 125 miles
per hour (mph) on the NEC-South End, and 110 mph on the NEC-North
End.
High-speed track means (1) a track on the main line of the NEC-
South End, where the authorized train speed for any class of train
exceeds 125 mph, or (2) a track on the main line of the NEC-North
End where the maximum authorized train speed for any class of train
is in excess of 110 mph.
Immediately adjacent track means a track within 30 feet of a
high-speed track when measured from track center to track center.
Signal and train control system means the automatic cab signal/
automatic train control system (cab signal/ATC) in effect on the NEC
at the date of issuance of this order, as supplemented by ACSES,
together with such modifications as Amtrak shall make consistent
with this order.
Explanation and analysis. In its comments, BLE-ATTD suggested that
FRA define the terms ``civil speed enforcement system'' (ACSES), ``off-
peak operating times,'' and ``repair facilities.'' As explained above,
the term ``off-peak operating times'' is no longer relevant since FRA
does not adopt its proposed window for nighttime operations. Similarly,
FRA believes it unnecessary to define ``repair facilities'' considering
the limited scope of this order. FRA has added a definition for
``ACSES'' that is derived from Amtrak's performance specifications.
The proposed order had suggested requiring ACSES on tracks
immediately adjacent to (within 30 feet of) high-speed tracks. In this
order, FRA extends the requirements for ACSES to trains operating on
immediately adjacent tracks where the maximum authorized speed exceeds
20 mph, since such tracks are located within the effective operating
envelope of high-speed tracks where derailments could endanger high-
speed operations.
Operations are already highly dense on the NEC-North End, with
projected increases in both freight and passenger traffic. Track
curvature on the NEC-North End also exceeds the average curvature on
the NEC-South End, resulting in greater potential concern for
compliance with civil speed restrictions. Accordingly, FRA
distinguishes between the two operations for purposes of determining
applicability of the new performance requirements.
Performance standards. Effective October 1, 1999, the following
performance standards and special requirements shall apply:
1. Except as provided in paragraph 9(b), the signal and train
control system shall enforce both permanent and temporary civil
speed restrictions (e.g., track curvature, bridges, and slow orders)
on all high-speed tracks and immediately adjacent tracks where the
maximum authorized speed exceeds 20 mph. Permanent restrictions
shall be loaded into the onboard computer by direct data transfer
from a verified database. Temporary restrictions shall be loaded
into the onboard computer by direct data transfer from the computer-
aided dispatching system. (For not to exceed 12 months following
cut-in of the system, use of temporary transponders programmed with
appropriate speed restrictions will be deemed to satisfy this
paragraph. Thereafter, use of temporary transponders alone shall be
acceptable only in the case of an emergency restriction for which
transfer of the restriction into the onboard computers of all
affected trains is not practicable.)
Explanation and analysis. As discussed above, the existing signal
system does not enforce temporary speed restrictions, such as slow
orders over defective track or protections for roadway workers. Amtrak
had proposed to use temporarily placed transponders, and entry of
restrictions into the on-board computer by milepost, to protect train
movements and workers and equipment on or adjacent to live high-speed
tracks. BLE-ATTD commented that this proposed use of temporary
transponders would be insufficient to enforce temporary speed
restrictions, and recommended as a failsafe that FRA also require the
train dispatcher to enter these restrictions into the on-board computer
by milepost.
FRA agrees with BLE-ATTD that temporary transponders should not be
routinely used to enforce temporary speed restrictions. Rather, the
dispatcher will automatically load temporary restrictions into the on-
board computer, through the computer-aided dispatching system and a
data radio network, to avoid the possibility of data entry errors by
the train crew. Amtrak may use temporary transponders as an alternative
routinely for the first 12 months after implementation of this order,
and only on an emergency basis thereafter. Data entry by train crews is
not an acceptable alternative.
FRA also clarifies that permanent restrictions will also be loaded
by direct data transfer from a verified database. FRA is not specifying
a method for verifying the database, but expects that Amtrak will
utilize appropriate reviews and field verifications to ensure a high
level of accuracy.
Nothing in this order excuses compliance with current Amtrak
requirements for creating and issuing appropriate authorities or for
providing protection for roadway workers. Amtrak has represented to FRA
that these protections will remain, supplemented by the additional
layer of safety provided by the ACSES. FRA will reopen consideration of
this order should Amtrak undertake any substantial revision of current
procedures that may have the effect of diminishing safety on the NEC.
2. Except as provided in paragraph 9(b), all trains operating on
high-speed track, immediately adjacent track where the maximum
authorized speed exceeds 20 mph, or track providing access to high-
speed track shall be equipped to respond to the continuous cab
signal/speed control system and ACSES.
Explanation and analysis. The benefits of equipping conventional
speed trains that operate on immediately adjacent tracks providing
access to high-speed tracks may derive primarily from enforcement of
positive stop features. If a train is prevented from inappropriately
proceeding through a junction and onto a high-speed track, the safety
of the subject train and the safety of the oncoming high-speed train
are equally assured. FRA believes that most equipped trains will make
use of high-speed tracks. (See the discussion in paragraph 9(b) below.)
As discussed above, FRA does not adopt its proposed nighttime
operations window and accordingly removes the proposed language from
this section.
3. No conflicting aspects or indications shall be displayed in
the locomotive cab.
Explanation and analysis. As explained above, FRA believes that
Amtrak's dual display (details of which are contained in the program
description placed in the docket of this proposed order) is appropriate
for a hybrid system such as this. The order
[[Page 39352]]
requires consistent information to be displayed to the locomotive
engineer. Amtrak plans to implement this principle, while providing
information from both the cab signal/ATC system and ACSES, by
displaying both of the resulting maximum speeds, with the lower speed
to be identified and enforced.
4. The system must enforce the most restrictive speed at any
location associated with either the civil/temporary restriction or
cab signal aspect.
Explanation and analysis. As discussed above, the most restrictive
of the limitations indicated by the cab signal/ATC or ACSES system will
be enforced.
5. At interlocking home signals and control points on high-speed
tracks or protecting switches providing access to high-speed tracks,
the signal and train control system shall enforce a positive stop
short of the signal or fouling point when the signal displays an
absolute stop. The system shall function such that the train will be
brought to a complete stop and cannot be moved again until the first
of the following events shall occur: (1) the signal displays a more
permissive aspect; or (2) in the event of a system malfunction, or
system penalty, the train comes to a complete stop, the engineer
receives verbal authority to proceed from the dispatcher, and the
engineer activates an override or reset device that is located where
it cannot be activated from the engineer's accustomed position in
the cab. The train may then only travel at restricted speed until a
valid speed command is received by the on-board train equipment. For
not to exceed 12 months following cut-in of ACSES, release of the
positive stop feature, under conditions where the signal displays an
aspect more favorable than stop, but not less favorable than
restricting, may be accomplished by use of the reset device;
thereafter, this function shall be accomplished automatically so
that it is not necessary for the engineer to leave his or her
accustomed position in the cab.
Explanation and analysis. As originally conceived by Amtrak, ACSES
would enforce a positive stop through an active transponder near the
distant signal which would recognize that the home signal is capable of
displaying an absolute stop, and enforce a positive stop even if the
home signal actually displayed a restricting indication. FRA requested
that Amtrak redesign this feature to better coordinate with the wayside
signals. Amtrak agreed to accelerate the development of the ACSES data
radio feature to reduce the need to operate the ``stop override''
button to only those instances where a system failure requires the
train to be moved. The Mobile Communication Package (MCP), a data radio
feature located at the interlocking, will broadcast a track specific,
direction specific, and location specific message to the approaching
train which automatically releases the stop-override feature without
the engineer having to operate the ``stop override'' button when the
home signal displays ``stop and proceed.'' This message will only be
transmitted and only be effective when the train is between the distant
signal and the home signal of the interlocking. If the signal displays
``restricting,'' the MCP data radio will broadcast a similar message to
the approaching train relieving the train from actually having to stop.
Over the past year, Amtrak has consistently advised FRA that MCP data
radios may not be installed at all interlockings for some time
following cut-in of the system. Amtrak has not been able to specify
when this element of the system would be completed. To resolve this
concern, FRA has added language to the order requiring that this
element of the system be completed not less than 12 months following
cut-in.
6. Failure modes of the system will allow for train movements at
reduced speeds, as follows:
a. Failure of Cab Signal/ATC System: In the event of failure of
the cab signal/ATC system on board a train, the cab signal/ATC
system will be cut out; however, ACSES shall remain operative and
enforce the 79 mph speed limit. If intermediate wayside signals are
provided, the train will continue to operate at speeds not exceeding
79 mph subject to indications of the wayside signal system. In
territory without fixed automatic block signals, the train will
receive information approaching the home signal, through the MCP
radio, with the information actually derived from the ``flashing
lunar signal with the letter ``C'' displayed at the home signal.''
When failure occurs after a train has entered such a block, the
train will proceed at restricted speed to the next interlocking and
may not pass the home signal, regardless of the aspect displayed,
until the flashing lunar ``Clear to Next Interlocking'' signal is
displayed. The train may then pass the signal and proceed at a speed
not to exceed 79 mph. This speed limit shall be enforced by ACSES.
Explanation and analysis. As proposed, the cab signal/ATC portion
of the system will be cut out under operating rules meeting 49 CFR
Sec. 236.567 requirements. When the cab signal/ATC portion of the
system fails and/or is cut out, ACSES will still be in operation, with
the central processing unit (CPU) receiving a message from the cab
signal/ATC CPU through a vital link that the cab signal/ATC is cut in
and not failed. If ACSES does not receive this message, a speed of 79
mph will be locked in and the display will be dark, other than the 79
mph displayed in the civil speed portion, which will be enforced. ACSES
will continue to enforce temporary and permanent speed restrictions and
positive stop at home signal locations.
b. ACSES failure. If the on-board ACSES fails en route, it must
be cut out in a similar manner to the cab signal/ATC system. The
engineer will be required to notify the dispatcher that ACSES has
been cut out. When given permission to proceed, the train must not
exceed 125 mph (NEC-South End) or 110 mph (NEC-North End). All
trains with cut out ACSES will operate at conventional train speeds.
Explanation and analysis. Amtrak's comments to the proposed order
recommended modifications in the proposed failure modes because the
phrase ``* * * unless a flashing lunar signal with the letter ``N''
reflected Amtrak's previous plan, which would present the ``clear to
next interlocking'' information to the train at the distant signal
through an active transponder at the location. Under Amtrak's current
plan, with the implementation of MCP radio at the interlocking, the
train will receive the information as it approaches the home signal,
with the information derived from the ``flashing lunar signal with the
letter ``C'' displayed at the home signal.''
FRA received no other comments on this proposed design standard,
which requires trains to fall back to existing maximum speeds when the
ACSES must be cut out on a train. However, this approach cannot provide
positive stop capability or compensate for higher curving speeds that
may be allowed using tilt HSTs. All trains with a cut out ACSES will
operate at conventional train speeds whether they are tilt train
equipment or conventional equipment. The vital link between CPUs
mentioned in 6(a) above will inform the signal CPU that the civil speed
CPU is cut out or has failed. The signal speed enforcement system will
enforce a default speed limit when ACSES has failed and/or is cut out,
with a maximum speed of 110 mph on the NEC-North End and 125 mph on the
NEC-South End if ACSES is cut out. This places a premium on compliance
with operating rules developed specifically for this purpose (copies of
which are available in the docket).
c. Cab signals/ATC & ACSES failure. If the cab signal/ATC system
and ACSES both fail en route, the systems shall be cut out and the
train shall proceed as provided in 49 CFR Sec. 236.567.
Explanation and analysis. FRA received no comment on its proposal
to follow the procedures and restrictions in Sec. 236.567 whenever the
signal and train control system fails and/or is cut out en route.
Accordingly, this section applies as follows whenever the signal and
train control system fails and/or is cut out en route:
Where an automatic train stop, train control, or cab signal device
fails and/
[[Page 39353]]
or is cut out enroute, train may proceed at restricted speed or if an
automatic block signal system is in operation according to signal
indication but not to exceed medium speed, to the next available point
of communication where report must be made to a designated officer.
Where no automatic block signal system is in use train shall be
permitted to proceed at restricted speed or where automatic block
signal system is in operation according to signal indication but not to
exceed medium speed to a point where absolute block can be established.
Where an absolute block is established in advance of the train on which
the device is inoperative train may proceed at not to exceed 79 miles
per hour.
These procedures, which are used with present train control systems
on the NEC and throughout the nation, have proven to be a reliable and
safe method of operating whenever the signal and train control system
fails and/or is cut out.
d. Wayside signal system failure. If the wayside signal system
fails, train operation will be at restricted speed to a point where
absolute block can be established in advance of the train. Where
absolute block is established in advance of the train, the train may
proceed at speeds not to exceed 79 mph.
Explanation and analysis. FRA received no comment on its proposal
to allow the carrier's operating rules to effect these requirements. If
a wayside signal system failure occurs, ACSES will continue to
function, by enforcing the 79 mph speed, civil and temporary speed
restrictions, and positive stops, but an absolute block and proceed not
to exceed 79 mph must still be established.
e. Missing transponder. If a transponder is not detected where
the equipment expected to find the next transponder, the train must
not exceed 125 mph (NEC-South End) or 110 mph (NEC-North End) until
the next valid transponder is encountered. The 125/110 mph speed
restriction will be enforced by the system and ``--'' will be
displayed to indicate that the civil speed is unknown. The audible
alarm for civil speeds will sound and must be acknowledged. Speed
restrictions previously entered into the system, whether temporary
or permanent, will be displayed at the proper time and continue to
be enforced. If the missing transponder is a positive stop
enforcement transponder at the distant signal to an interlocking,
then the system will treat the missing transponder as if it were
present and a stop will be required. Since the previous transponder
will have transmitted the distance to the stop location, the stop
shall be enforced unless a cab signal is received that indicates the
interlocking signal is displaying an aspect more favorable than
``Stop,'' ``Stop & Proceed,'' and ``Restricting.'' The 125/110 mph
speed restriction will also be enforced regardless of whether the
cab signal aspect is being received.
Explanation and analysis. As proposed, permanent transponders will
be programmed with information that includes distance to the next
transponder. Wheel rotations will be logged to determine train position
between transponders. If a transponder is missing (or is not
successfully read), speeds will be slowed to 125 or 110 mph, depending
upon the territory involved, until the next valid transponder is
detected.
7. When it becomes necessary to cut out the cab signal/ATC
system, ACSES, or both, these systems shall be considered
inoperative until the engine has been repaired, tested and found to
be functioning properly. Repairs shall be made before dispatching
the unit on any subsequent trip.
Explanation and analysis. FRA received no comment on this section,
which is adopted as proposed.
8. Other requirements applicable to the system are as follows:
a. Aspects in the cab shall have only one indication and one
name, and will be shown in such a way as to be understood by the
engine crew. These aspects shall be shown by lights and/or
illuminated letters or numbers.
b. Entrances to the main line can be protected by electrically
locked derails if the speed limit is 15 mph or less. A transponder
set shall cut in ACSES prior to movement through the derail and onto
the main line. If the speed limit is greater than 15 mph, a positive
stop will be required. At entrances from a signaled track, ACSES
shall be cut in prior to the distant signal and a positive stop
enforced at the home signal.
Explanation and analysis. FRA received no comment on these
sections, which are adopted as proposed.
c. An on-board event recorder shall record, in addition to the
required functions of Sec. 229.5(g) [of FRA's Railroad Locomotive
Safety Standards (49 CFR Part 229)], the time at which each
transponder is encountered, the information associated with that
transponder, and each use of the positive stop override. These
functions may be incorporated within the on-board computer, or as a
stand alone device, but shall continue to record speeds and related
cab signal/ATC data, even if ACSES has failed and/or is cut out. The
event recorder shall meet all requirements of Sec. 229.135.
Explanation and analysis. The NTSB supported requiring the on-board
event recorder to record the time each transponder is encountered, any
associated information, and each use of the positive stop override. At
a minimum, the event recorder specifications submitted by Amtrak
require the recorder to log with time stamps the following data: speed,
distance traveled, location by milepost in miles and tenths, track
number, brake pipe pressure (for penalty applications), on/off status
of ACSES, driver input to ACSES/system acknowledge on/off, transponder
messages received, and data from ACSES sent to the driver's display
unit and the diagnostic serial port of the driver's diagnostic panel.
9. The following maximum speeds apply on the NEC in territory
subject to this order:
a. In ACSES territory where all trains operating on high-speed
tracks, adjacent tracks where speeds exceed 20 mph, and tracks
providing access to high-speed tracks are equipped with cab signal/
ATC and ACSES, qualified and ACSES-equipped trainsets otherwise so
authorized may operate at maximum speeds not exceeding 150 mph. The
maximum speed over any highway-rail crossing shall not exceed 80
miles per hour where only conventional warning systems are in place.
Train speeds shall not exceed 95 mph over any highway-rail crossing
where arrangements approved by the Associate Administrator for
Safety incorporating four-quadrant gates and presence detection are
provided and tied into the signal system, such that a train will be
brought to a stop should the crossing be determined to be occupied
following descent of the gates. Amtrak shall submit for approval of
the Associate Administrator for Safety plans for site-specific
improvements with timetables for each of the 13 NEC crossings
remaining on the NEC-North End by January 1, 1999.
Explanation and analysis. As discussed above, FRA extends the
requirements for ACSES to trains operating on immediately adjacent
tracks where the maximum authorized speed exceeds 20 mph. Speeds are
permitted to 95 mph, rather than 80 mph as proposed, provided 4-
quadrant gates with presence detection are provided and tied into the
train control system. FRA may consider amendment of this order to allow
alternative secure arrangements at one or more private crossings
following submission of a required crossover safety plan. This section
is otherwise adopted as proposed.
b. In ACSES territory on the NEC-South End, where access to any
high-speed track is prevented by switches locked in the normal
position and a parallel route to the high-speed track is provided at
crossovers from adjacent tracks, and where no junctions providing
direct access exist, qualified and ACSES-equipped trainsets
otherwise so authorized may operate to a maximum speed not exceeding
135 mph on such track; and provisions of this order requiring other
tracks and trains to be equipped with the ACSES do not apply.
Explanation and analysis. FRA received no comment on this section,
which is adopted as proposed. Currently maximum speeds for trains on
the general rail system are limited to 110 mph. Under a waiver, Amtrak
operates
[[Page 39354]]
Metroliner service on the NEC-South End at speeds up to 125 mph. This
order allows Amtrak to increase its speeds on the NEC-South End to 135
mph by installing the ACSES transponders on the wayside and by
equipping new high-speed trainsets with on-board scanners and
computers. Other users of Amtrak's NEC-South End high-speed tracks are
not required to be equipped for the present, but will benefit from the
higher level of safety associated with Amtrak operations. On the NEC-
North End, maximum speeds currently top out at 110 mph, with no waiver
for high-speed service. This order authorizes operation of qualified
trainsets at up to 150 mph in territory where Amtrak has installed
ACSES on the wayside, provided Amtrak and other users are equipped.
The phrase ``otherwise authorized,'' as applied to trains, refers
to equipment qualified for higher speeds under the track/vehicle
interaction limits adopted in the recent revisions to the Track Safety
Standards. Metroliner equipment is currently authorized to operate up
to 125 mph. FRA anticipates that the new American Flyer trainsets will
be qualified to operate up to 150 mph. Other equipment presently
operating on the NEC may also qualify to operate at higher than
conventional speeds under the revised Track Safety Standards.
10. Schedule and acceptance requirements.
a. This order is effective August 21, 1998.
b. Not later than 45 days following publication of this order,
Amtrak shall deliver to the Associate Administrator for Safety, FRA,
a final program and timetable for completion of pre-qualification
tests, submission of final production specifications, availability
of on-board equipment from Amtrak's vendor, staging of installation
of on-board equipment for which Amtrak takes responsibility, and
testing of all wayside and on-board equipment prior to cut-in.
c. Contingent upon FRA's acceptance of the final program and
timetable, and FRA's acceptance of the results of pre-qualification
and pre-service tests, compliance with requirements of this order
for use of ACSES on the NEC-North End is required on and after
October 1, 1999.
d. Amtrak may commence operations under paragraph 9(b) of this
order utilizing equipment qualified under 49 CFR Part 213, as
revised, following FRA's approval of the elements of the final
program, timetable and test results pertinent to the subject
territory and operations.
Explanation and analysis. Several commentators noted concerns
regarding the ability of Amtrak, its vendor and other railroads to
stage installation and testing of ACSES within the remaining time
available. FRA shares this concern, but believes sufficient time
remains prior to scheduled initiation of electrified operations and
high-speed service to address these needs if Amtrak and its vendor move
briskly, but deliberately, to complete final specifications and tests.
FRA also has noted the need to ensure the quality of pre-service
testing of this new system. Although the various elements of the ACSES
system have been routinely used in train control applications
internationally, integration of the system remains a challenge.
Although Amtrak has extensive experience and an excellent record in
implementing train control technology, oversight is appropriate to
verify that safety remains the first priority in this undertaking.
Accordingly, FRA has included a requirement for submission of a
program and timetable for staging the implementation of this system in
a manner that does not impair the ability of other railroads to provide
quality passenger and freight service. FRA will expect that this
timetable reflect consultation with other parties, as necessary and
appropriate, and describe how adverse impacts on other parties will be
prevented. FRA will cooperate with this process by providing one or
more program monitors, who will oversee pre-qualification and pre-
service testing of all aspects of the system, advising the Associate
Administrator for Safety regarding the readiness of the system as
measured against the requirements of this order.
FRA will continue to evaluate the ability of the parties subject to
this order to meet the technical requirements specified without
disruption of normal rail service and may amend the order as necessary
to avoid any such disruptions.
Environmental Impact
FRA has evaluated this final order of particular applicability
under its procedures for ensuring full consideration of the potential
environmental impacts of FRA actions, as required by the National
Environmental Policy Act (42 U.S.C. 4321, et seq.) and related
directives. This order meets the criteria for classification as a non-
major action for environmental purposes.
Regulatory Flexibility Act
The Regulatory Flexibility Act of 1980 (5 U.S.C. 601 et seq.) was
enacted by Congress to ensure that small entities are not unnecessarily
and disproportionately burdened by Government regulations. Only one
small entity is affected by this order, P&W. Their annual revenues are
about $22,000,000, and this order will cost them about $1,100,000 in
total discounted costs over twenty years. The twenty-year cost is thus
about 5% of one year's revenue. This is a substantial impact on that
one entity. This order is, however, only one part of a much larger
infrastructure improvement, and much of the benefit of that improvement
accrues to P&W, including the opening of rail access for double stack
intermodal service to the site of the former U.S. Navy facilities at
Quonset Point and Davisville, Rhode Island, at a cost to the Federal
taxpayer estimated at $55 million. Also, as an adjunct to the current
improvement project, P&W will be the beneficiary of construction of a
third track on the NEC between Davisville and ``Boston Switch'' that
will provide the new doublestack access that otherwise would not exist.
P&W is the only freight railroad operating over those tracks. While the
one-time cost of ACSES is a significant fraction of one year's revenue
for P&W, the other projects will add far more than that to P&W's net
worth, enabling them to compete effectively against other modes. They
do not at present face rail competition.
As noted above, P&W operates on the NEC largely as a result of an
expedited supplemental transaction effected under section 1155 of the
Northeast Rail Service Act of 1981 (NERSA) (45 U.S.C. 745). Pursuant to
that statute, and under an order of the Special Court established by
the Regional Rail Reorganization Act of 1973, Conrail was compelled to
surrender certain properties and service rights to a successor railroad
that would commit to providing at least 4 years of service on the
properties transferred. P&W aggressively pursued that opportunity, with
the full knowledge that public planning from the 1960's forward had
focused on dramatic passenger service improvements on the NEC between
New York and Boston. As recently as the past year, P&W has sought to
extend its service rights farther west into Connecticut based upon
P&W's claim that the proposed acquisition of Conrail by NS and CSX
constitutes a termination of Conrail's residual franchise and
activation of rights P&W enjoys under the Special Court's order.
FRA has sought to identify means to mitigate the impact of this
order on P&W. The proposed order would have permitted operations of
unequipped trains during nighttime hours when high-speed trains were
not running. P&W commented that it would not be feasible to limit its
train operations to night time, the window within which the order
proposed to permit non-equipped trains to run on the NEC,
[[Page 39355]]
since nighttime switching service would result in a dramatic increase
in costs, cause operational disruptions for P&W customers, disrupt
neighborhoods, and raise serious safety issues. P&W has thus explained
that the means suggested in the proposed order would not be helpful,
but has not suggested any alternate means of mitigating the impacts
that are compatible with early realization of reasonable returns from
public investments in improved rail service in the region. As a result
of those investments, P&W will be provided access to a third main track
over a key route, and with improved clearances, at a cost to the
Federal Government almost 50 times greater than the cost to P&W of
installing ACSES on its equipment. Further, it is clear that P&W (like
all operators on the subject territory) will realize substantial
benefits from ACSES. Under these circumstances, FRA is unable to
determine that P&W is unduly disadvantaged by the mandate of this
order.
Most importantly, FRA believes that there is no alternative that
could meet the safety concerns which are FRA's primary mission without
imposing similar costs on P&W. The Regulatory Flexibility Act makes
clear that concerns about small entities are not to take precedence
over the government's responsibility for public safety. Further, it is
not the purpose of railroad safety regulations and orders to allocate
societal costs among parties with shared interests in transportation
improvements. Nevertheless, FRA states unequivocally that it does not
by issuance of this order intend to deprive P&W of any claim it may
have against Amtrak related to the assignment of responsibility for the
cost of these safety improvements.
Paperwork Reduction Act
Under the Paperwork Reduction Act of 1995 (PRA), Pub. L. No. 104-
13, Sec. 2,109 Stat. 163 (1995) (codified as revised at 44 U.S.C.
Secs. 3501-3520), and its implementing regulations, 5 CFR Part 1320,
the Office of Management and Budget (OMB) does not need to approve
information collection requirements that affect nine or fewer
respondents. FRA has determined that information collection
requirements in this order will affect fewer than nine railroads, and
that therefore OMB approval is not required.
Regulatory Impact
Executive Order 12866 and DOT Regulatory Policies and Procedures
This rule has been evaluated in accordance with existing policies
and procedures, and has been determined to be non-significant under
both Executive Order 12866 and DOT policies and procedures (44 FR
11034; February 26, 1979). FRA has prepared and placed in the docket a
regulatory analysis addressing the economic impact of the rule.
Document inspection and copying facilities are available at 1120
Vermont Avenue, 7th Floor, Washington, DC, 20590. Photocopies may also
be obtained by submitting a written request to the FRA Docket Clerk at
Office of Chief Counsel, Federal Railroad Administration, 400 Seventh
Street, SW, Washington, DC 20590.
Even though full implementation of ACSES would cost about $200
million, FRA is not ordering that here, nor does FRA plan to require it
at present. For the portion of ACSES ordered here, FRA estimates that
the direct safety benefits will exceed $44 million, discounted to
present value over a 20-year period, through prevention of collisions,
overspeed derailments, and incidents involving harm to roadway workers.
Additional benefits are expected to include avoidance of other public
investments in transportation infrastructure in the region. The
allocated cost for installation and maintenance of ACSES on the
segments affected by this order is expected to be $36 million for the
same period, yielding a net benefit to society of at least $8.5
million, exclusive of non-safety benefits. Of this amount, costs of
installation on the right-of-way and on equipment will be about $33
million, which is expected to be spread over three calendar years.
FRA has based its analysis on many assumptions, which yield a great
deal of uncertainty. The projected accident rates may be significantly
lower without ACSES, in which case the analysis would overstate
benefits. FRA believes it is equally likely that the analysis
underestimates the accident rate without ACSES, in which case the
analysis would understate benefits.
There are several reasons for the uncertainty. The track safety
standards have recently been modified, and will permit railroads to set
maximum speeds on curves according to a performance standard which will
likely permit higher maximum speeds on curves on the affected segments.
This will leave less of a margin for error should the engineer permit
the train to exceed the civil speed restriction for a curve on which
the maximum speed has been increased. At the same time the corridor
will be electrified. This will allow the use of electric locomotives
which are capable of more rapid acceleration, and therefore are capable
of violating civil speed restrictions more often, for longer durations
and by greater speeds. FRA realizes that traffic on the affected
segments will increase (as did A. D. Little, the firm that analyzed the
risks of high speed service for Amtrak), but the consequences of this
increase can only be estimated, and this estimate is itself based on
uncertain volume estimates.
The largest uncertainty, however, comes from the fact that the root
cause of the kinds of accidents which ACSES may prevent is human
failure. Human failure occurs somewhat randomly, and is very difficult
to predict. FRA is aware that the more opportunities for human failure
exist, the greater the likelihood of such failure, but there is no way
to say with certainty that so many human failures will occur within
such a period.
If one accident like the 1996 Silver Spring, Maryland accident (11
killed, 24 injured) is prevented, this rule will more than pay for
itself. That accident was a relatively low speed collision between an
Amtrak train and a commuter train, not on the affected segments. Higher
speed accidents could easily have costs many times the total cost of
the order (for example, the Chase, Maryland accident in 1987 which left
16 killed, 228 injured). Even accidents where a collision is not the
first event can be severe. In 1990, an Amtrak train derailed because of
overspeed on a curve in Boston, and struck a train on an adjacent track
(451 injured). In June 1998, a German high-speed train derailed and
struck a bridge, killing approximately 95 people. Although that train
was not derailed because of overspeed and did not have crash-energy
management systems (as far as we now know), it was travelling at 125
mph, a lower speed than trainsets will be capable of on this corridor,
and may be illustrative of what a high-speed derailment could cause.
FRA has already taken steps to see that high-speed trains on this
corridor will have crash-energy management systems, but avoiding
derailments and collisions with conventional passenger trains is
extremely desirable. While it is impossible to know whether this will
prevent something which may never happen, or multiple events,
preventing just one major accident in twenty years will make the system
pay for itself.
Accordingly, for the reasons stated in the preamble, FRA issues the
following Final Order:
Final Order of Particular Applicability
Authority: 49 U.S.C. 20103, 20107, 20501-20505 (1994); and 49
CFR 1.49(f), (g), and (m).
[[Page 39356]]
Scope and Applicability
This order supplements existing regulations at 49 CFR Part 236 and
existing orders for automatic train control on track controlled by the
National Railroad Passenger Corporation (Amtrak) on the Northeast
Corridor (NEC). This order applies in territory where Amtrak has
installed wayside elements of the Advanced Civil Speed Enforcement
System (ACSES), permitting high-speed operations under the conditions
set forth below.
All railroads operating on high-speed tracks in such equipped
territory between Boston, Massachusetts and New Haven, Connecticut
(NEC-North End), or on tracks providing access to such high-speed
tracks, shall be subject to this order, including the following
entities operating or contracting for the operation of rail service--
Amtrak;
Connecticut Department of Transportation;
Consolidated Rail Corporation and its successors;
Massachusetts Bay Transportation Authority; and
Providence and Worcester Railroad Company.
The requirement that all trains be equipped with operative on-board
ACSES applies as specified in paragraph (2) from milepost 73.2 at New
Haven, Connecticut, to South Station, Boston, Massachusetts, but
applies only to high-speed trains operating on high-speed tracks
between Washington, DC, and New York, New York (NEC-South End), as set
forth in paragraph 9(b).
Definitions
Unless otherwise provided terms used in this order have the same
definitions contained in Part 236. For purposes of this order--
ACSES means a transponder based system that operates independent of
the cab signal system, and provides enforcement of permanent speed
restrictions, temporary speed restrictions, and stop signals at
interlockings.
High-speed train means a train operating in excess of 125 miles per
hour (mph) on the NEC-South End, and 110 mph on the NEC-North End.
``High-speed track'' means (1) a track on the main line of the NEC-
South End, where the authorized train speed for any class of train
exceeds 125 mph, or (2) a track on the main line of the NEC-North End
where the maximum authorized train speed for any class of train is in
excess of 110 mph.
Immediately adjacent track means a track within 30 feet of a high-
speed track when measured from track center to track center.
Signal and train control system refers to the automatic cab signal/
automatic train control system (cab signal/ATC) in effect on the NEC at
the date of issuance of this order, as supplemented by ACSES, together
with such modifications as Amtrak shall make consistent with this
order.
Performance Standards
Effective October 1, 1999, the following performance standards and
special requirements shall apply:
1. Except as provided in paragraph 9(b), the signal and train
control system shall enforce both permanent and temporary civil speed
restrictions (e.g., track curvature, bridges, and slow orders) on all
high-speed tracks and immediately adjacent tracks. Permanent
restrictions shall be loaded into the onboard computer by direct data
transfer from a verified database. Temporary restrictions shall be
loaded into the onboard computer by direct data transfer from the
computer-aided dispatching system. (For not to exceed 12 months
following cut-in of the system, use of temporary transponders
programmed with appropriate speed restrictions will be deemed to
satisfy this paragraph. Thereafter, use of temporary transponders alone
shall be acceptable only in the case of an emergency restriction for
which transfer of the restriction into the onboard computers of all
affected trains is not practicable.)
2. Except as provided in paragraph 9(b), all trains operating on
high-speed track, immediately adjacent track where the maximum
authorized speed exceeds 20 mph, or track providing access to high-
speed track shall be equipped to respond to the continuous cab signal/
speed control system and ACSES.
3. No conflicting aspects or indications shall be displayed in the
locomotive cab.
4. The system must enforce the most restrictive speed at any
location associated with either the civil/temporary restriction or cab
signal aspect.
5. At interlocking home signals and control points on high-speed
tracks or protecting switches providing access to high-speed tracks,
the signal and train control system shall enforce a positive stop short
of the signal or fouling point when the signal displays an absolute
stop. The system shall function such that the train will be brought to
a complete stop and cannot be moved again until the first of the
following events shall occur: (1) the signal displays a more permissive
aspect; or (2) in the event of a system malfunction, or system penalty,
the train comes to a complete stop, the engineer receives verbal
authority to proceed from the dispatcher, and the engineer activates an
override or reset device that is located where it cannot be activated
from the engineer's accustomed position in the cab. The train may then
only travel at restricted speed until a valid speed command is received
by the on-board train equipment. For not to exceed 12 months following
cut-in of ACSES, release of the positive stop feature, under conditions
where the signal displays an aspect more favorable than stop, but not
less favorable than restricting, may be accomplished by use of the
reset device; thereafter, this function shall be accomplished
automatically so that it is not necessary for the engineer to leave his
or her accustomed position in the cab.
6. Failure modes of the system will allow for train movements at
reduced speeds, as follows:
a. Failure of Cab Signal/ATC System: In the event of failure of the
cab signal/ATC system on board a train, the cab signal/ATC system will
be cut out; however, ACSES shall remain operative and enforce the 79
mph speed limit. If intermediate wayside signals are provided, the
train will receive information approaching the home signal, through the
MCP radio, with the information actually derived from the ``flashing
lunar signal with the letter ``C'' displayed at the home signal.'' When
failure occurs after a train has entered such a block, the train will
proceed at restricted speed to the next interlocking and may not pass
the home signal, regardless of the aspect displayed, until the flashing
lunar ``Clear to Next Interlocking'' signal is displayed. The train may
then pass the signal and proceed at a speed not to exceed 79 mph. The
speed limit shall be enforced by ACSES.
b. ACSES failure. If the on-board ACSES fails en route, it must be
cut out in a similar manner to the cab signal/ATC system. The engineer
will be required to notify the dispatcher that ACSES has been cut out.
When given permission to proceed, the train must not exceed 125 mph
(NEC-South End) or 110 mph (NEC-North End). All trains with cut out
ACSES will operate at conventional train speeds.
c. Cab signals/ATC & ACSES failure. If the cab signal/ATC system
and ACSES both fail en route, the systems shall be cut out and the
train shall proceed as provided in 49 CFR Sec. 236.567.
d. Wayside signal system failure. If the wayside signal system
fails, train
[[Page 39357]]
operation will be at restricted speed to a point where absolute block
can be established in advance of the train. Where absolute block is
established in advance of the train, the train may proceed at speeds
not to exceed 79 mph.
e. Missing transponder. If a transponder is not detected where the
equipment expected to find the next transponder, the train must not
exceed 125 mph (NEC-South End) or 110 mph (NEC-North End) until the
next valid transponder is encountered. The 125/110 mph speed
restriction will be enforced by the system and ``--'' will be displayed
to indicate that the civil speed is unknown. The audible alarm for
civil speeds will sound and must be acknowledged. Speed restrictions
previously entered into the system, whether temporary or permanent,
will be displayed at the proper time and continue to be enforced. If
the missing transponder is a positive stop enforcement transponder at
the distant signal to an interlocking, then the system will treat the
missing transponder as if it were present and a stop will be required.
Since the previous transponder will have transmitted the distance to
the stop location, the stop shall be enforced unless a cab signal is
received that indicates the interlocking signal is displaying an aspect
more favorable than ``Stop,'' ``Stop & Proceed,'' and ``Restricting.''
The 125/110 mph speed restriction will also be enforced regardless of
whether the cab signal aspect is being received.
7. When it becomes necessary to cut out the cab signal/ATC system,
ACSES, or both, these systems shall be considered inoperative until the
engine has been repaired, tested and found to be functioning properly.
Repairs shall be made before dispatching the unit on any subsequent
trip.
8. Other requirements applicable to the system are as follows:
a. Aspects in the cab shall have only one indication and one name,
and will be shown in such a way as to be understood by the engine crew.
These aspects shall be shown by lights and/or illuminated letters or
numbers.
b. Entrances to the main line can be protected by electrically
locked derails if the speed limit is 15 mph or less. A transponder set
shall cut in ACSES prior to movement through the derail and onto the
main line. If the speed limit is greater than 15 mph, a positive stop
will be required. At entrances from a signaled track, ACSES shall be
cut in prior to the distant signal and a positive stop enforced at the
home signal.
c. An on-board event recorder shall record, in addition to the
required functions of Sec. 229.5(g) [of FRA's Railroad Locomotive
Safety Standards (49 CFR Part 229)], the time at which each transponder
is encountered, the information associated with that transponder, and
each use of the positive stop override. These functions may be
incorporated within the on-board computer, or as a stand alone device,
but shall continue to record speeds and related cab signal/ATC data,
even if ACSES has failed and/or is cut out. The event recorder shall
meet all requirements of Sec. 229.135.
9. The following maximum speeds apply on the NEC in territory
subject to this order:
a. In ACSES territory where all trains operating on high-speed
tracks, adjacent track where the maximum authorized speed exceeds 20
mph, and tracks providing access to high-speed tracks are equipped with
cab signal/ATC and ACSES, qualified and ACSES-equipped trainsets
otherwise so authorized may operate at maximum speeds not exceeding 150
mph. The maximum speed over any highway-rail crossing shall not exceed
80 mph where only conventional warning systems are in place. Train
speeds shall not exceed 95 mph over any highway-rail crossing where
arrangements approved by the Associate Administrator for Safety
incorporating four-quadrant gates and presence detection are provided
and tied into the signal system, such that a train will be brought to a
stop should the crossing be determined to be occupied following descent
of the gates. Amtrak shall submit for approval of the Associate
