[Description] This report summarizes the results of a detailed stress analysis and fatigue assessment of two stub sill tank car designs often used for the transport of hazardous materials. This particular class of railroad cars has come under scrutiny by the Federal Railroad Administration in recent years because of occasional stub sill tank car failures that have led to the release of hazardous materials. The United States and Canadian governments asked the tank car industry to inspect at least 1,100 tank cars, perform a theoretical analysis of the stub sill problem, and then evaluate the inspection results compared with theoretical calculations.
