Abstract

The object of the invention is a device for protecting track relays (9), controlled by two voltages V₁ and VL having a phase difference of 90°, utilized in so-called "single-track" track cir­ cuits.
According to the invention, the supply voltage Vc applied to the track circuit and the local voltage VL applied to the track relay (9) are supplied through polarity change switches CC and CL.
