Control and maintenance device for spacing between rail vehicles - uses transmitters and receivers in vehicles and lines of specified attenuation are laid along tracks

摘要

The device maintains the distance in a branching area. The vehicles are provided with circuits transmitting signals of a specified amplitude, and receivers with a specified sensitivity. They are coupled with lines with specified attenuation installed along the track. At least two lines per track are provided, with one allocated to each vehicle transmitter and receiver, and the other only to a receiver in each vehicle. Connections are made at regular intervals between the outler line of a track and an inner line of the other track. The two-wire connections (41) are inductively coupled in series with the lines (9) allocated to the senders.
