ABSTRACT: The Federal Railroad Administration, with supplemental support from the Association of American Railroads (AAR), Railway Progress Institute, and Chemical Manufacturers Association, contracted with the Transportation Technology Center, Inc., a subsidiary of AAR (then organized as AAR, Transportation Technology Center), to conduct a full-scale damage tolerance analysis (DTA) validation test on a tank car using the Simuloader. This is one of five companion reports that detail North American tank car industry efforts since 1992 to assess the operating environment and apply DTA principles to tank car design. These efforts included an over-the-road operating environment survey, material spectrum variable testing, a full-scale fatigue crack growth test, fractographic analysis of the full-scale test vehicle, and DTA analytical model validation and application guidance. This document covers only the details of the 300,000-spectrum mile full-scale DTA validation test.
