Abstract:In a continuing effort to improve rail safety, reduce the number of injuries and fatalities to rail workers, and reduce the impact of train accidents on the environment, the Federal Railroad Administration (FRA), the Association of American Railroads, and the locomotive builders have worked cooperatively to review the performance and design of locomotive fuel tanks. The FRA undertook this project to further advance understanding of the performance of locomotive fuel tanks and to identify opportunities for further improvement to enhance their crashworthiness. A finite element model of a “generic” fuel tank was the basis for the analysis of three static crash scenarios and one dynamic loading case. Results of these analyses illustrate the power of this approach in determining the contribution of alternative design changes to fuel tank crashworthiness. The results also suggest several practical and cost-effective design improvements.
