ELECTRIFICATION HAS IMPACT ON SIGNALING

Electrification with its parallel power lines can interfere with signal systems. The effects of earth voltage gradients can cause foreign current to flow in track circuits. Electrostatic and electromagnetic induction due to inductive coupling exists between the power lines, track circuits and open wire C&S lines. Accidental contact between phase wires of the power line and some part of the signal system cause interference to the latter.
