At approximately 1:37 a.m. on January 18, 2002, Canadian Pacific Railway freight train 292-16 derailed 31 of its 112 cars about 12 mile west of the city limits of Minot, North Dakota. Five tank cars carrying anhydrous ammonia catastrophically ruptured, and a vapor plume covered the derailment site and surrounding area. One resident was fatally injured, 11 people sustained serious injuries, and 322 people, including the 2 train crewmembers, sustained minor injuries. Damages exceeded $2 million and more than $8 million has been spent for environmental remediation. The major safety issues identified in this accident are Canadian Pacific Railway's programs and practices for the inspection and maintenance of joint bars in its continuous welded rail; The Federal Railroad Administration's oversight of continuous welded rail maintenance programs; and tank car crashworthiness, specifically the adequacy of non-normalized steels to resist tank fracture propagation. The analysis also addresses the appropriateness of non-normalized steels to resist tank fracture propagation. The analysis also addresses the appropriateness of using shelter-in-place to protect the public from the release of hazardous material. As a result of its investigation of this accident, the Safety Board makes safety recommendations to the Federal Railroad Administration and the Canadian Pacific Railway. |
