A National Transportation Safety Board Railroad Accident Report (1973) describes the accident which occurred in a shunting yard in East St. Louis, Illinois. Arriving cars are classified in the yard, then delivered to outbound carriers. On arrival, cars are inspected. They are then pushed up a mound, uncoupled, and allowed to roll down a descending grade onto one of the classification tracks. This process is called humping. Cars are directed and controlled by a computerized switching and speed-control system.

Local partial confinement or obstruction in a vapor cloud may easily act as an initiator for detonation, which may propagate into the cloud as well. So far, however, only one possible unconfined vapor cloud detonation has been reported in the literature it occurred at Port Hudson, Missouri (National Transportation Safety Board Report 1972 Burgess and Zabetakis 1973). In most cases the nonhomogeneous structure of a cloud freely dispersing in the atmosphere probably prevents a detonation from propagating.

The National Transportation Safety Board (NTSB) has found much evidence to indicate the probable cause of the January 6, 2005, collision and derailment of Norfolk Southern train 192 in Graniteville, South Carolina, was the failure of the crew of Norfolk Southern train P22 to return the main line switch to the normal position after the crew completed work at an industry track. Contributing to the severity of the accident was the puncture of the ninth car in the train, a tank car containing chlorine, which resulted in the release of poison gas.

It is common for crash investigators to undertake reconstruction of the aircraft wreckage, and this can be exceptionaUy useful in estabhshing the seat of an explosion, if that is what in fact took place. The National Transportation Safety Board in the United States and the United Kingdom Air Accident Investigation Branch have both done some exceptionaUy fine work of this type.
