ABSTRACT: This report summarizes Test 3, a crippling load test on Budd Pioneer Car 244, conducted on June 28, 2011. Before the crippling load test, Transportation Technology Center, Inc., conducted two 800,000-pound (lb) quasi-static tests on Car 244 in accordance with Code of Federal Regulations 49 CFR 239.203. The tests, which are summarized in this report, applied compressive end loads along the line of draft to ensure that Car 244 was suitable for the crippling load test. Car 244 was previously modified to include a crash energy management (CEM) system, and it was subjected to several impact tests. For the crippling load test, the CEM system was removed. Loads were applied at the four CEM pockets on one end of the car and reacted at the CEM pockets on the other end. Crippling first occurred on the roof at approximately 1,070,000 lb, and complete car crippling occurred at approximately 1,200,000 lb. Crippling occurred on the side sills, center sill, side walls, and roof near the loading end. The total car length after the test was reduced by approximately 3 inches. The instrumentation for this test measured car strains, displacements, and compressive forces.
