Simulation of freight train operations with departures ahead of schedule

Abstract

Many lines in Sweden have mixed traffic, with both passenger and freight trains. In contrast to passenger trains, freight trains can deviate significantly from their timetable. This study evaluates the effect of modelling freight trains running ahead as well as behind schedule. In previous Swedish studies freight trains have been modelled as being on time or delayed. RailSys is used to simulate a section of the Southern Main Line and a fictive double-track line. Simulation results are compared to data from real train operations. Results show that freight trains can be modelled in a more realistic way. This can improve simulation analysis of freight operations. © 2014 WIT Press.
