In recent years, train-based signalling systems have drawn the infrastructure managers’ attention, in the attempt to improve the line capacity and to optimize traffic. The development of a Moving Block (MVB) signalling system may offer a solution to achieve these objectives. MVB signalling relies on the definition of an occupied region which moves together with the train, which is continuously updated based on the information exchanged between the vehicle and the Radio-Block-Centre (RBC). Thus, it may safely operate an increased level of traffic on railway networks. Despite its potential benefits, there is still no real implementation of this system, which would require on-site testing operations, considering several scenarios. In the attempt to enhance the overall procedure moving towards the target of “zero on-site testing”, in this work a simulation tool for MVB signalling is proposed. The simulator is developed in Matlab-Simulink environment and presents a modular and expandible architecture. It includes a behavioural model of the driver and allows for the injection of disturbances to the train motion, enabling to test unusual operational scenarios, without any risk.
