ABSTRACT:
A system for testing a plurality of subsystems in a multi-car train over a train-wide communications network includes at least one master station and a plurality of slave stations interconnected by the train-wide communications network, each station collecting status and diagnostic information from associated slave subsystems and providing the information upon request. A portable test unit is provided for testing the subsystems by requesting status and diagnostics information about at least one of the plurality of slave subsystems over the communications network. A diagnostic interface is provided in the at least one master station for interfacing the portable test unit to the master station to facilitate transmission of data between the portable test unit and the train-wide communications network.
