Abstract
A device comprises a detector for detecting markers along the railway track processor for processing the signals supplied by the detector, in order to control the speed of a rail vehicle as a function of its position and instantaneous speed on a track section. The markers comprise, on each track section, markers (1) arranged at constant or random intervals at the entry of each section and markers (2) arranged to form a beacon for identifying the section in question and for initializing the device. The signal processor comprises a memory (9) in which a vehicle progress program is stored in the form of codes associated with each marker arranged on the ground and each containing a data item relating to the type of ground marker which is to be detected, a data item relating to a set-point speed of the vehicle on a level with the marker, and a data item relating to the number of the track section covered.
