ABSTRACT: Under Federal Railroad Administration (FRA) Contract No. DTFR 53-93-C-00001, Task Order Number 115, the Transportation Technology Center, Inc. (TTCI), a subsidiary of the Association of American Railroads (AAR), conducted a multi-phase research project focusing on the field assessment of damage to tank cars that have been involved in accidents. Phase I of the project focused on evaluating the technical foundations for the current tank car damage assessment guidelines developed by the AAR in the 1980's. A formal technical literature search conducted by Stanford Research Institute (SRI) identified which guidelines could be validated and which required additional modeling and validation in the project's Phase II effort. The Phase II effort of this research project was intended to accomplish the following: Assess the validity of the existing guidelines using laboratory experiments and computer modeling; Estimate their margin of safety; Develop an analysis method for generating a damage assessment handbook. This report uses the results of the Phase I and Phase II results to generate new guidelines.
