Abstract

The track section to be monitored is connected with an AC source across connection terminals, which taps the still existing AC voltage at the end of the length (IGK) of the track section. This is used for the indication of the clear or occupied condition of the track. For the production of a dynamic signal at the end of the track section, a circuit arrangement is provided, parallel to the connection terminals (8,9) for the voltage tapping, for periodic modulation of the amplitude of the AC voltage. The frequency of modulation is small in comparison to this AC voltage. An indicating unit responds to the alteration of the amplitude of the AC voltage.
