Abstract
An end of train device for an electrically controlled pneumatic brake system includes a radio transceiver, a brake pipe sensor, a brake pipe valve, a manual switch and a first controller controlling the radio transceiver and the valve. It also includes a wire transceiver for wire communication over a train line and a second controller connected to and controlling the wire transceiver. The first and second controllers are connected to each other and control the radio transceiver to be active when the wire transceiver is active. Two batteries are provided with an improved power management circuit to individually charge the batteries.
