Abstract
Electrical connections are provided between coupled railway cars by a connector which mates with the industry standard brake line air hose connector. Electrical contacts may be imbedded in the mating surfaces of two joined connectors, or on modules attached to the standard connector. The valve which admits air to the air hose connector after it is joined to another connector may also actuate a switch which completes electrical circuits when the air valve is opened. In cases where end to end reversal of a railway car would cause interchange of circuits, a compensating switch is provided.
