A mesoscopic simulation modelling methodology for analyzing and evaluating freight train operations in a rail network

This paper includes a mesoscopic simulation modelling methodology developed for analysing and evaluating freight train operations in a rail network. The product of this methodology is a simulation rail network model implemented using an event-based simulation computer package called SIMUL 8. For simulation modelling purposes a decomposition approach is used. This approach allows us to separate the rail network under study into its components such as rail lines, rail yards, rail stations, rail terminals and junctions. The components of the rail network are thought of as interconnected queuing systems that interact and influence one another, so that the global impact of freight train operations in a rail network is captured.The products presented in this paper are of interest to rail freight tactical management, where global benefits are pursued.
