FIELD: transport.
SUBSTANCE: invention relates to railway transport, particularly to rail circuits and can be used in, for example in hump centralisation system. Hump rail circuit comprises isolated rail line (3), power supply (1), adjusting resistors (6) and track relay (8), matching transformer (2), actuator (10) and control (9) relays, measuring (7), limiting (5) and loading (4) resistors. Loading resistor (4) is connected to one ends of isolated rail line (3). Secondary of matching transformer (2) is connected to other ends of said rail line (3). Primary of matching transformer (2) has one terminal connected to one terminal of power supply (4) and second terminal connected, via measuring (7), limiting (5) and loading (4) resistors, with second terminal of power supply (1). Contacts of track (8) and control (9) relays are connected with actuator relay (10) mounted on ES station.
EFFECT: higher reliability of rail circuit.
