Abstract (en)

[origin: EP0890495A1] The method involves measuring the entry speed of each vehicle axle entering the section (1) of track using a speed sensor. The entry speed is used with the braking characteristic of the one or more rail brakes (5) to derive a start and end time point (t0-t4) for the period during which the axle occupies part (11,13,15) of the track section. An auxiliary signal is generated at the start time point and is reset at the end time point for each vehicle axle's occupation of the section of track. The control signal (st) is generated if there is no auxiliary signal.
