Abstract:The Federal Railroad Administration (FRA) sponsors research on safety topics to address and to improve safety regulations and standards. This paper is part of a series of papers that describe the testing and analysis used to evaluate passenger locomotive fuel tank integrity. Fuel tank integrity federal regulations, as well as industry standards, currently exist in the form of a series of static load conditions. The static load conditions are a set of prescribed loads on all passenger fuel tanks, which set a minimum level of protection against impacts that might puncture the tank and cause the release of diesel fuel. If diesel fuel is ignited in an impact incident, collision or derailment, the crew and passengers may be at risk. In the current research program a series of dynamic impact tests and quasi-static tests were conducted that measure the forces required to deform a fuel tank and investigate the types of loading conditions experienced by fuel tanks.
