Abstract Railroads constitute an important mode of transport for both freight and passengers. In the United States, for example, railroads are responsible for 35.6% of total intercity freight transport and enjoy approximately 30% of total revenues of all carriers. However; due to severe competition from other modes, the rail industry is eager to improve its operational efficiency and rationalize its planning decisions further. The role of analytical models in supporting managerial decision-making thus assumes renewed importance. This reports on the existing literature models for rail transportation with two goals in mind: (a) to collect and categorize rail modelling efforts, and (b) to position the rail-related literature in the context of other transportation models and provide an introduction to this field for nonspecialists. Optimization, queueing, and simulation models are all treated with particular emphasis on optimization. The role of each class of models is discussed in relation to its function and its position within the total planning activity of a railroad. A concluding section outlines the major modelling obstacles and promising areas for future development.
