Abstract: Rail signalling solutions designed by Thales integrate conventional signalling technology with advanced systems based on the European Train Control System (ETCS) standard. The degree of integration is classified according to the different levels defined in this standard. Level 1 is still based on light signals, but Eurobalises increasingly replace national intermittent train protection systems. Thales has provided equipment for several national level 1 projects. In level 2 a continuous train supervision is achieved. The Radio Block Centre (RBC) developed by Thales is responsible for the centralised protection of train movements for lines that are operated with level 2 equipment. It receives a train’s position from its onboard unit and the trackside signalling information from the interlocking system. With this information and with the properties of the underlying track map it generates the movement authority for the train. In various European projects the interoperability of the Thales RBC with signalling equipment of other manufacturers has been proven
