ABSTRACT: The Transportation Technology Center, Inc. conducted impact tests on three locomotive fuel tanks as part of the Federal Railroad Administration’s locomotive fuel tank crashworthiness improvement program. Three fuel tanks, two from EMD F40PH locomotives and one from an EMD F40 locomotive, served as test specimens. A 14,075-pound impact cart equipped with a 12-inch by 12-inch impactor struck the tanks; fuel tanks 232 (F40PH) and 202 (F40) were impacted at their geometrical centers at 4.2 mph and 6.2 mph, respectively. Fuel tank 234 (F40PH) was offset from the center in the horizontal direction and impacted between the baffles at 11.2 mph. No fuel tanks ruptured. Results of the tests were eventually used for validation and refinements of finite element models developed by the John A. Volpe National Transportation Systems Center.
