audio frequency track circuits (AFTC) [8]. High-frequency track circuits (HFCT) eliminate the need for insulated joints in the running rails [9]. Because insulated joints are expensive to install and to maintain, eliminating them leads to a significant cost reduction. Eliminating insulated joints also allows the track circuit to operate with ...
