[Federal Register Volume 62, Number 39 (Thursday, February 27, 1997)] [Notices] [Pages 9014-9015] From the Federal Register Online via the Government Publishing Office [www.gpo.gov] [FR Doc No: 97-4939] ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Railroad Administration Notice of Safety Bulletin AGENCY: Federal Railroad Administration (FRA), Department of Transportation (DOT). ACTION: Notice of safety bulletin. ----------------------------------------------------------------------- SUMMARY: The FRA is issuing Safety Bulletin 97-2 addressing a recommended safety practice to stop trains on heavy descending grades of 2 percent or greater by initiating an emergency application of the train's air brakes whenever the train speed exceeds the maximum authorized speed by five miles per hour or more. FOR FURTHER INFORMATION CONTACT: Doug Taylor, Staff Director, Operating Practices Division, Office of Safety Assurance and Compliance, FRA, 400 Seventh Street, S.W., Washington, D.C. 20590 (telephone 202-632-3346). SUPPLEMENTARY INFORMATION: Background Preliminary investigatory findings following the January 12, 1997, derailment of a run-away Union Pacific Railroad Company (UP) freight train on a 2.2 percent descending grade at Hayden, California, indicate that when the train reached a speed of 11 miles per hour above its maximum authorized speed, the engineer initiated an emergency application of the train's air brakes. Following the emergency brake application, the train continued to accelerate out of control and derailed at the entrance switch to a controlled siding. FRA has studied this accident and compared it with another run-away freight train derailment that occurred on the Cajon Subdivision of the Burlington Northern Santa Fe Railway (BNSF) four miles west of Summit, California, on February 1, 1996. Following that derailment, the BNSF implemented a ``five mile per hour rule.'' The railroad's rule requires that if a freight train exceeds the maximum authorized speed by five miles per hour while descending the grade on the Cajon Pass between Summit and Baseline, the train must be stopped by using an emergency application of the train's air brake system. The UP initiated a similar rule at 24 locations on their system following the January 12, 1997, Hayden, California, derailment. While FRA does not approve of train operations at any speed above the maximum allowable speed established by Federal regulations or by railroad rule, FRA does support the initiatives taken by both the BNSF and UP to address the situation described here. FRA continues to believe that properly maintained equipment and proper instruction on train handling techniques, that adequately cover normal and emergency operating procedures on heavy grades, would prevent nearly all situations in which a train would be exceeding the allowable speed. However, if a simple, easy to implement practice could help prevent run-away trains, whatever the cause of the excessive train speed, that practice should be encouraged. The suggested practice provides an additional measure of safety since it reduces the uncertainty inherent in ``judgement calls'' as to when to initiate emergency action when descending a heavy grade. The recommendation, based on UP's and BNSF's ``five mile per hour rule'' reduces the possibility that train speed will increase to a point where escalating energy levels prohibit stopping the train's momentum even with the retarding force generated by an emergency train brake application. Recommendation In recognition of the difficulty or impossibility of stopping a train on a heavy grade once a critical train speed is attained, FRA strongly recommends that railroads take the following safety precautions: 1. On descending grades of 2 percent or more, a train must be stopped, using an emergency application of the train's air brakes, if the train's speed reaches 5 miles per hour more than the train's maximum authorized speed. 2. After the train has stopped: a. a sufficient number of hand brakes must be applied to secure the train; b. once secured, the train must be inspected and no further train movement will be made until authorized by a designated railroad employee. 3. The railroad must conduct an immediate investigation into the cause of the incident and initiate appropriate corrective action. 4. Event recorder data must be routinely inspected to ensure full understanding and compliance with this rule. [[Page 9015]] Issued in Washington, D.C. on February 24, 1997. Bruce M.
