| titleOfInvention | Route interlocking control system |
| abstract | ROUTE INTERLOCKING CONTROL SYSTEM ABSTRACT OF THE DISCLOSURE A single relay serves to register route request selections for both traffic directions over each track route through a railroad interlocking layout. This single route request relay is jointly controlled by the route selection push buttons for both directions, the actuated push button being also repeated by a traffic direction relay. The route request relay pick up checks that no conflicting route request is active, and that the same or opposing route is not already established and locked. The route request and direction repeater relays are held by stick circuits to store the request until the route is locked. A single relay serves to provide the clear and lock function for all possible traffic routes originating at each entry point into the interlocking. Each clear and lock relay responds to the registry of a route request originating at that location but also checks, in accordance with the route switch positions, that the opposing approach lock relay is still picked up, that the involved track sections within the interlocking are unoccupied, and the absence of cab signal energy for an opposing train within the interlocking. The clear/lock relay selects and enables the clearing of the correct route entry signal, releases the route request storage, and locks the established route against any opposing route request. Cancellation of a route request or a locked route with cleared signal is provided, with separate actions as the approach track is or is not occupied. Cancellation of a locked route and cleared signal requires the usual time delay to assure that an approaching train stops short before a con-flicting move is authorized. |
