Abstract
A system includes a track system having a first rail and a second rail, a track activity detection circuit electrically connected to each of the first rail and the second rail, a track shunt circuit electrically connected to the first rail and the second rail, wherein the track shunt circuit is configured to selectively electrically connect the first rail and the second rail through a shunt. A method includes receiving an instruction to apply a shunt between a first rail and a second rail of a track system, and electrically connecting the first rail to the second rail through a controllable track shunt circuit.
