A system for electrically connecting two locomotives coupled in a consist and each having a pair of live electrical receptacles thereon located one at each end on opposite sides of the longitudinal vertical center plane includes an elongated jumper cable having connector heads at each end is permanently mounted on one end of the locomotive by an elongated flexible support having one end attached intermediate the connector heads. A pair of dummy receptacles are mounted one on each side of the locomotive in position to each have one of the connector heads of the permanently mounted jumper cable connected thereto so that, when not in use, the jumper cable extends generally across the end of the locomotive and has one end supported on each side portion thereof and its intermediate portion supported between the two dummy receptacles. To use the jumper cable to provide electrical connection between two coupled locomotives, the connector heads are disconnected from the dummy receptacles and one is connected to the permanently installed electrical receptacle on the locomotive on which the jumper cable is permanently mounted and the other connected to the permanently installed electrical receptacle on the adjacent end of the next locomotive. Alternatively, electrical connection can be provided between the locomotives by an independent, nonattached jumper cable, leaving the permanently attached jumper cable connected to the dummy receptacles.
