Abstract (en)
[origin: EP0340597A2] During shunting, it occasionally occurs that a points-circuit zone is prematurely reported as free below an unusually long vehicle by the associated track free report device. Special measures then have to be taken in order to prevent the points turning below this unusually long vehicle. For this purpose, the invention provides for the free report signal of the track free report device (GFAW) only to be evaluated as a free report of the associated track section if it has been ensured that all the axles of a vehicle (FZ) or a group of vehicles travelling over the section have previously travelled into the section. For the first section in the driving direction of a track system, this is determined by an indicator (EL) which detects the completion of the passing of the vehicle or of the group of vehicles. The indicator signal (EFWA) which occurs earlier in time is connected to the free report signal (GFWA &uarr& ) of the track free report device to form a vehicle end code (FEZA) which indicates that the vehicle or the group of vehicles has left the first track section. This vehicle end code (FEZA) is connected, as the vehicle or group of vehicles advances further, to the free report signal (GFZA &uarr& ) of the track free report device of the following track section to form a new vehicle end code (FEWB) for this section which indicates that the second section is completely cleared. This process continues as the vehicle or group of vehicles advances from section to section. <IMAGE>
