ABSTRACT:
A railway track circuit surge suppression system for the protection of wayside equipment from transitory energy surges appearing in the rails. The system has a primary surge suppression stage typically near the rails and a secondary surge suppression stage typically near the equipment to be protected. The secondary stage comprises an apparatus having a pair of inductors arranged serially with the respective track line wires to oppose the flow of surging current. Thus, the much of the energy dissipates at the primary stage. Remaining energy is dissipated by a voltage clamp behind the inductors.
