Simulation Model of Belgrade Suburban Passenger Trains Service Using OpenTrack

Abstract – In this paper, simulation models, created in the OpenTrack simulation tool, were used to compare the proposed timetable with a variant in which all trains from and Lazarevac would be extended to Belgrade Center. This paper aims to analyze the effects of the increasing number of trains on part of Belgrade railway junction from Resnik to Belgrade Center. The results have shown that the section from Dedinje junction to Resnik has more than enough capacity for the increased number of trains. Also, the simulation results show us that when the number of trains increases by 40%, BG trains can operate without or with acceptable delays. Keywords – railway, simulation, BG voz, OpenTrack.
