ABSTRACT:
Method and apparatus for central spacing control of track-operated vehicles, particularly railroad vehicles, along paths which are subdivided into individual track sections for the positioning of the vehicles, which sections are continuously monitored as to occupation, in dependence upon the instantaneous position of the vehicles, preferably utilizing stationary information systems, particularly for railroad systems with a dense train succession and track section lengths, and without continuous information channels between vehicles and a main office, in which each of the track sections is continuously monitored in the main office, with respect to occupation thereof by a vehicle or a series of coupled vehicles, to determine whether the path sections ahead of and/or behind the occupied distance, representing a predetermined minimum distance between successive vehicles or series of coupled vehicles, are free of vehicles, and providing an actuating signal, when a section indicated as occupied is within the path range defined by the minimum distance, operative to initiate a forced braking of the following vehicle or vehicles.
