Simulation modelling is the efficient approach to analyse train traffic on a selected line or on a complex railway node. Simulation model uses an interaction between rail vehicles and infrastructure according to predefined procedures and timetable to compute parameters of train movement, track occupation, and capacity utilization. We propose a High-Level Petri Nets model that incorporates all interlocking and operating rules, infrastructure data, timetable and train delays data. In a Petri net environment, trains are tokens, track sections are places, and transitions are discrete events of train moving according to interlocking principles. Model has a hierarchy structure where each specific section is defined as a subsystem. Results from the simulation model are used to create reports on sections occupancy, train movement, for drawing of train's time-distance graphs, and for animation of train movement. Model is tested on the selected railway line for analyses of the denivelation of the junction in the Belgrade railway node. [ABSTRACT FROM AUTHOR]
