  • Patent number: 5139198
    Abstract: Tracks for electric model railways have a track body provided with ties and metal rails secured to its upper surface. The electrical and mechanical connections between adjacent track bodies occur in two end-face connection zones. In order to obtain improved electrical and mechanical connections, a recess is formed in the track body at the connection zones of each track. The recess is open toward a bottom and toward a connection plane, and is not visible from above. A separate connecting element has two identical heads symmetric about a central axis. The heads are snapped into the recesses of two adjoining tracks to provide a secure and invisible connection.
