Title: Railway traffic braking monitoring system on sectioned track - uses signal transfer device along track and automatic selection of highest permitted speed as monitoring criterion
Inventor: ZIMMER RUDOLF ING GRAD
IPC: B61L3/12
Filed: 1977-03-04
Abstract: A railway traffic monitoring system for automatic or manually-operated signalling on track divided into sections has a light signal controlled by a track busy signalling device and a signal transfer device relaying "track free" or "track busy" information to passing trains. The signal transfer device is placed at a distance before the light corresp. to the highest permitted speed and the braking delay, and a board braking distance monitoring triggered by the signal forces braking when the actual speed is too high. Manual triggering required when the train has already passed the transfer device when the light changes colour can lead to wrong operation. This is eliminated by using transfer device along the track and automatic selection of the highest permitted speed as the monitoring system criterion.
