1. A method for placing a multi-car train with a communication network in an energy saving layup mode, the communication network having a master node interconnected to at least one node via a train bus, the train having a head car for carrying the master node and at least one other car for carrying the at least one other node with an intelligent subsystem unit coupled to the train bus by the other node, the intelligent subsystem unit controlling auxiliary systems of the at least one other car, the head car including an operator console for controlling the train through the master node, the method comprising the steps of:

  • transmitting a shutdown signal from the operator console to the master node to disable operation of the train;

    sending in response to the shutdown signal an shutdown message from the master node to the at least one other node after a delay of a predetermined amount of time, the train being in a layup mode during the predetermined amount of time wherein the train is not operational but auxiliary systems controlled by the intelligent subsystem unit of the train are kept running; and

    subsequently shutting down power to the intelligent subsystem unit with the at least one other node in response to receiving the shutdown message at the at least one other node after the expiration of the predetermined amount of time.
