Application of simulation models in capacity constrained rail corridors

This paper focuses on the practical value of using and selecting rail simulation models to find real solutions to real problems in constrained traffic corridors. It discusses issues which simulation can address, where quantitative results cannot be derived by any other method. A second section highlights differences among rail simulation models and the suitability of each kind to different types of problems. The third section discusses some derived parametric line capacity relationships between physical plant characteristics and train operations.
