FIELD: railway signaling and communication.
SUBSTANCE: proposed track circuit contains two lines and matching devices connected with said lines and also track generator, track receiver, transmitter, impulse track and track relays, pulse pickup, time delay unit, time delay relay, diodes and resistors. Action of device fro checking condition of track lines is based on comparing voltage at their inlet ends.
EFFECT: improved reliability of checking and accuracy of tracing of displacement of standard shunt and shunt of larger resistance at two fold longitudinal asymmetry of insulation resistance on adjacent track sections.
