A power supply vital monitor for track circuits for railway systems includes a track segment that is separated from adjacent segments by electric joints. Each track segment includes a signal transmitting unit and receiving units for transmitting and receiving train presence detection signals and/or transmitting or receiving communication signals between the train and the track segment. The transmitting unit and receiving units are connected to a common power supply line. To avoid an erroneous clearing of an occupied status caused by spurious signals on the power supply line affecting reception of the train detection signals, each receiving unit includes a first and a second channel, which connect the receiver with the corresponding track circuit and with a power supply sensor connected to the power supply line. Switches enable and disable connections of the receivers to the corresponding track circuit and to the corresponding power supply sensor.
