Abstract This report documents a study performed to identify and analyze twenty-two of the important computer-based models of railroad operations. The models are divided into three categories: network simulations, yard simulations, and network optimizations. The simulations are used to assess the impact of certain operating policies and planning procedures. The network simulations examine system-wide effects, while the yard simulations focus on the operations performed within a single yard. Network optimizations typically are used to calculate optimal distribution for a rail system's empty freight cars based on the railroad's car distribution rules and goals. The description of each model includes its history, design approach, fundamental logic, unusual features, hardware and software specifications, and its extent of application. In the case of a model's implementation on a rail system, attempts were made to obtain test results and evaluations. This served as a basis for reviewing each model.
