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 thatdoi:10.2495/cr100081 fatcat:o7h6ki3qm5dmdkm5pqrm7pb47i
