ABSTRACT: One of the objectives of the Truck Design Optimization Project (TDOP) Phase II is to define the performance of newer Type II freight car truck designs versus the standard, three-piece Type I truck. To accomplish this dynamic performance evaluation, TDOP Phase II will utilize field test data and analytical tools. The analytical tools, consisting primarily of freight car truck simulation models and their supporting computer programs, will be used to extend and interpret the field test results. The purpose of this report is to document the selection of candidate analytical tools from existing models and computer programs for validation and for use in TDOP Phase II. This report establishes the assessment criteria, surveys 59 existing analytical tools, evaluates in detail 16 of the more promising, and from these, selects a set of tools for validation and subsequent use on TDOP Phase II.
