An electrically insulating mechanical joint checker for mechanical joints (21, 22) connecting rails of following track segments (11, 12) of a railway line, each track segment forming part of a track circuit. The track segment (11,12) comprises electric signal transmitting units (3) and receiving units (4) for transmitting and receiving train presence detection signals within said track segment and/or relating communication signals between the train (7) and the track segment. The said train presence detection signals and said communication signals comprise a further joint detection signal, generated and transmitted by the transmitting units (3) and received by the receiving units (4) belonging to the same track segment (11), being the joint detection signal relating to the track segment (11) different at least in respect to the one relating to the adjacent track segments (12). The invention relates also to a method to detect a failure or breakage of a mechanical joint inside a track segment (11).
