An electrical bus 5 extends from a control unit 1 and, in use, runs the length of the train between the front and rear vehicles (2a,b). An RFID tag (3a,b) is mounted on each of the vehicles and is operatively connected to the bus so that each tag may communicate with the control unit. The control unit determines the integrity of the train by interrogating the tags, which each encode a unique identifier to identify the vehicle to which it is mounted. This determination may be done repeatedly. The connection 9 of the bus between vehicles may be integrated with mechanical couplings 10 of the vehicles so that the bus is electrically terminated upon decoupling of the vehicles. The tags may contain read-only or rewritable data, and may be encased by hermetically sealed enclosures. A second bus and tag system may be used concurrently (Fig. 1) to provide redundancy.
