The National Transportation Safety Board (NTSB) reported that the collision between an Amtrak train and three Conrail locomotives on 4 Jan. 1987 was caused by impairment of the engineer of the Conrail locomotives from marijuana and by the failure of and lack of safety devices. Evaluation of NTSB's report does not support marijuana impairment as a cause of the accident, but it does reveal many safety problems.
