The conventional steady energy DC track circuit, the coded track, single- and double-element AC, the single-rail, double-rail and jointless track circuits are discussed in terms of their variables and the basic limitations of 0.06 ohm shunting sensitivity and broken-rail protection. Source voltage, track relays, ballast resistance and rail impedance are explained for each case.
