The Distributed Railway Signalling System (DRSS) is a new signalling system, in which all devices including trains, switch point and signals, as well as position checking, interact and exchange information based on some logic constraint relations. These devices operate independently to ensure train safety. Based on this idea, we have presented the concept of modelling these device actions with G-nets (an Object-oriented Petri Net tool) in Comprail 2006. In this paper, a simulation system that

The simulator is based on the concept of DRSS and includes mainly six classes and their functionality modules: station layout automatic generation, train operation, position checking, switch point and signal. In addition, the instance generation of all classes and timetable design are considered in the simulator. It is possible to verify and simulate almost all functions with this simulator, such as train protection, route process, interlocking logic verification and terminal device procedure, etc.
