Simulation of a railway mainline junction using High level Petri nets

Railway transport is one of the most complex kind of transport. Solving railway infrastructure problems and conflict situations is very difficult task. This paper presents a simulation model of mainline railway junction using High level Petri nets. The aim of the paper is to detect the conflict situations in station and analyses impact of infrastructure elements malfunction on train delays. Model was tested on mainline station Mjölby in southeastern Sweden.
