Abstract
A coupling for connecting model cars of a model train includes an integrated resilient contact supported by a first coupling member disposed against a mating electrical connector of a second coupling member. The first and second coupling members are configured to bear mechanical tension and compression, while permitting vertical movement of one coupling relative to the other. The resilient contact and mating contact are configured to maintain an electrical connection during relative vertical movement of the coupling members. Using the coupling, separate cars of a model train may be placed in electrical communication with one another without requiring a separate electrical connector. A wireless connection may also be made through the coupling.
