RAILROAD ACCIDENT REPORT: DERAILMENT OF AMTRAK TRAIN NO. 8, THE EMPIRE BUILDER, ON BURLINGTON NORTHERN TRACK, LOHMAN, MONTANA, MARCH 28, 1979

About 5:50 p.m. on March 28, 1979, Amtrak train No. 8, The Empire Builder, operating on Burlington Northern track, derailed nine cars at Lohman, Montana. Forty-eight persons were injured in the derailment, and the property damage was estimated to be $333,500. The National Transportation Safety Board determines that the probable cause of this accident was the cracking from overheating of the right rear wheel on the trailing truck of baggage car 1248. The cracked wheel moved inward off the axle seat and decreased the wheel-to-wheel gage. Contributing to the accident was the inadequate maintenance and inspection of the car, which allowed it to continue in service in violation of minimum safety standards. As a result of its investigation of this accident, the Safety Board made two recommendations to the Burlington Northern concerning equipment inspection procedures and one joint recommendation to the Burlington Northern and Amtrak to insure that inspection and maintenance schedules are maintained, and to be certain they are done efficiently.
