Abstract
The present disclosure generally relates to shunt devices for providing multi-fold protection for track workers. For example, a failsafe shunt device may have a pair of end components magnetically couple to two running rails and a central unit connected to the pair of end components via electrical wires. The failsafe shunt device may communicate with an operations control center (OCC) to indicate a presence of the shunt device. Related methods of using disclosed shunt devices and associated systems are also described.
