Abstract: An improved electrical jumper system, for a locomotive consist for hauling trains, is provided by an installation that converts an existing single-headed receptacle, for receiving one end of a non-permanent jumper cable, into a multiple-headed permanent system that alternatively may be used either to receive a cable head from another locomotive unit, as was the previous purpose of the existing receptacle, or to provide a permanently installed jumper cable that assures presence of equipment at all times to properly electrically connect the units of the consist.
