(Case No. 6977) ABSTRACT OF THE DISCLOSURE Insulated joint failure detectors are placed at each controlled signal location in the railroad interlocking to detect the condition of the insulated joints and also the passage of each truck of a train moving in either direction past that signal. Contacts individually responsive to detector operation serially control the lockout of cab signal transmitter to inhibit the transmission of cab signal commands within the interlocking if an insulated joint fails or an unauthorized train overruns a controlled signal. These detector contacts are individually bypassed by parallel circuit paths, controlled either by the corresponding home signal relay or cab signal control relays properly energized along an established route, in order to prevent lockout when the train is authorized to pass that signal location.
