Abstract: An electrically insulating mechanical joint checker for mechanical joints connecting rails of following track segments of a railway line, each track segment forming part of a track circuit. The track segment includes electric signal transmitting units and receiving units for transmitting and receiving train presence detection signals within the track segment and/or relating communication signals between the train and the track segment. The train presence detection signals and communication signals include a further joint detection signal, generated and transmitted by the transmitting units and received by the receiving units belonging to the same track segment, the joint detection signal relating to the track segment being different at least in respect to the one relating to the adjacent track segments. The invention relates also to a method to detect a failure or breakage of a mechanical joint inside a track segment.

Abstract: 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.
