Abstract:

In an electronic track relay, electronic relay circuitry receives an input track signal coded at a pre-determined code rate, and regenerates the input track signal at the pre-determined code rate after a predetermined time delay. A driving circuit is coupled to the electronic relay circuitry for receiving the delayed track signal therefrom and conducting, at the predetermined code rate, at least a power source to at least one of various components in a railroad signaling system. A latching circuit is configured for latching the driving circuit into one among a plurality of configurations respectively corresponding to a plurality of different signaling location types, depending on a signaling location type of the railroad signaling system in which the electronic track relay is installed.
