FIELD: transport. ^ SUBSTANCE: invention relates to railway signaling, centralisation and interlocking equipment, particularly, to traffic spacing control at station limits. Interlocking comprises track circuit including two high-power supplies, transmitter relay with resistant limiter terminal, two matching transformers, impulse track relay and track lines. Besides, it comprises two low-power power supplies, four band filters, three limiter resistors, two track repeaters with terminals, two linear positive relays with terminals, two linear negative relays with terminals, second transmitting relay with terminals, second impulse track relay with terminals, and two code track transmitters, and capacitor in low-power source circuit. ^ EFFECT: reduced current spreading in rail circuit and power consumption. ^ 1 dwg |
