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.
Claims21
A system comprising:
- a track activity detection circuit electrically connected to each of a first rail and a second rail of a track system;
- and
- at least one track shunt circuit connected to the first and second rails through the track activity detection circuit, wherein the at least one track shunt circuit is configured to selectively electrically connect the first rail and the second rail through a shunt.
A system comprising:
- a track activity detection circuit electrically connected to each of a first rail and a second rail of a track system;
- and
- a track shunt circuit connected to the first and second rails by the track activity detection circuit, the track shunt circuit comprising a shunt control system and a shunt device, wherein the shunt control system is configured, responsive to receiving a control signal from a remote location, to automatically control the shunt device for transitioning from a first operative state, in which the first rail is not electrically connected to the second rail through the shunt device, to a second operative state, in which the first rail is electrically connected to the second rail through the shunt device.
A system comprising:
- a track shunt circuit configured to be electrically connected to first and second rails of a track system through a track activity detection circuit, the track shunt circuit comprising a shunt control system and a shunt device, wherein the shunt control system is configured, responsive to receiving a control signal from a remote location and when the track shunt circuit is installed for electrical connection to the first and second rails, to automatically control the shunt device for transitioning from a first operative state, in which the first rail is not electrically connected to the second rail through the shunt device, to a second operative state, in which the first rail is electrically connected to the second rail through the shunt device.
