A system () and method is provided that facilitates controlling signaling devices along railroad tracks in electrified territory. The system may include a first track circuit transmitter () connectable to a first end () of a first block () of a railroad track (). A first processor () may be configured to determine a first signaling aspect () corresponding to a visible light signal outputted by a first signaling device () and cause the first track circuit transmitter to transmit a first code () corresponding to the first signaling aspect via a first AC carrier signal () through rails () of the first block of the railroad track. The system may also include a first track circuit receiver () connectable to a second end () of the first block of the railroad track, which is configured to receive the first AC carrier signal through the rails of the first block of the railroad track and demodulate the first code from the first AC carrier signal. A second processor () may be configured to determine a second signaling aspect () based at least in part on the first code that was demodulated and cause a second signaling device () to output a visible signal corresponding to the second signaling aspect.
