TANK WAGONS THAT SURVIVE DERAILMENT

The conclusion of a U.S. Department of Transportation study to reduce the hazards of tank car transportation is cited. A primary hazard of tank cars undamaged during derailment is explosion caused by extreme heat from burning cars in the accident. The pressure relief valves now in service are incapable of discharging the contents sufficiently fast to prevent explosion. A secondary pressure-relief device of substantial capacity such as a rupture disc is recommended for all but highly toxic materials.
