Jointless Track Circuits

Railway Track Circuit Configuration

Railway Track Circuit Configuration Double and Single Rail Track Circuit Configuration Railway Track Circuit Configuration :– Double rail track circuit arrangements have both rails fitted with IRJs to completely isolate a track circuit. Impedance bonds are used when a traction current return path is required. IRJs are not required with jointless track circuits and fewer […]
