Abstract: A system for connecting and disconnecting rail vehicle system for storing, transporting, and delivering bulk electric energy using railroads is described. The system includes. The system includes at least one rail vehicle system. The rail vehicle system includes a locomotive and a group of rail cars. The group of rails cars includes several rail cars with energy storage, power electronics and communication system. The rail car further includes a pantograph. The system also includes a plurality of electrical feeders. The electrical feeders are substantially dedicated for providing power transfer to and from the respective groups of rail cars. The system further includes at least one position controls system.

Abstract: A system for use with a locomotive or an off-highway vehicle (OHV) processor controlling an auxiliary device. A driver selectively energizes the auxiliary device. A driver switch for selectively activates the driver. A driver controller area network (CAN) microcontroller controls the driver switch. A panel switch selectively supplies power to the driver CAN microcontroller and the driver switch. A power distribution system connects the driver CAN microcontroller and the driver switch to the panel switch. A panel CAN microcontroller responsive to the processor controls the panel switch.

Abstract: The invention refers to a circuit for the busy indication of track sections (1, 2, 3, 4) electrically isolated from each other of a model railway system digitally controlled by a control center (Z). After a controlled digital receiver (E) of an engine determines its own address code with the help of a decoding device, it provides a busy signal via a signal generator (8) to the assigned busy indicator (BM3). To simplify the circuit considerably and to be able to do without the the RF-signal generators so far used in the engine and corresponding RF-receivers of the busy indicator, the signal generator of each engine (A, B) comprises a d.c. source providing a busy signal of a given polarity corresponding to the engine direction on the track as the busy signal to the busy indicator (BM3).
