Abstract
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 other 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 method includes transmitting a shutdown signal to the master node; sending in response to the shutdown signal a shutdown message from the master node to the at least one other node after a predetermined amount of time; and shutting down power to the intelligent subsystem unit in response to receiving the shutdown message at the at least one other node.
