A comprehensive and generic risk assessment model has been developed for evaluating the risk to the public from the transportation of hazardous materials (Hazmat) on rail over specified routes. The model considers the various operational and Hazmat property parameters. The model developed was utilized to evaluate the risks posed in transporting LPG, chlorine and sulfuric acid on two (alternative) routes between the same origin-destination pair. Historical main line and yard accident data together with the current volumes of transportation of the specified Hazmats were considered. The results are presented in the form of risk profiles. Safety measures, such as head shields and shelf couplers, seem to reduce, substantially, the annual frequency of high casualties but seem to have less impact on the low casualty end of the risk profile. A similar positive effect in risk reduction is seen from emergency response action following an accident. Sensitivity of the risk profiles to various other parameters were also investigated.
