Title: Device for track-free signalling, train location and velocity measurement.
IPC: B61L25/02
Filed: 1983-09-30
Abstract: The invention relates to a device for train location and track-free signalling in the field of an electronic actuator, the actuating groups of which contain microcomputers and are connected to one another via geographic data lines arranged according to the route of the track.
