Installing traffic control on a railway network and radio encoder combines

The invention relates to a control device (42) comprising an automatic traffic supervision system trains and IXL interlocking systems (34) manage the engagement state of a plurality of lineside equipment (20 ) to allow movement of a first vehicle according to a first principle of the type "district to district." To allow movement of a second vehicle (46) according to a second principle of the residual distance type, device (42) comprises an interface system (52) comprising: - a communication network (54), - an encoder radio (56), and - base stations (58). The radio encoder (56) is used to emulate an environment for controlling the movement of the second vehicle (46) according to the second principle, when said second vehicle is traveling on a railway infrastructure implementing a traffic control according to the first principle.
