Abstract: The present disclosure generally relates to work block encroachment warning systems for providing protection for rail workers working in a mobile or fixed work block. For example, a vehicle (V)-aware unit installed on a moving rail vehicle and a work block limit encroachment unit mounted on a railroad may wirelessly communicate with each other to determine a distance between them. When a vehicle is moving toward an occupied work block, the distance may be used to identify potential hazards.

Abstract: Inter-vehicle communications for avoiding rear collision of rail vehicles on a railroad that includes, for example, a collision avoidance system. The collision avoidance system may comprise an end-of-train device and a V-aware unit located on different vehicles. The two devices may be configured to wirelessly communicate with each other, and then detect each other's presence by estimating a distance between them. Warnings may be issued to respective operators against a collision hazard when the distance drops to or below a pre-determined threshold.

Abstract: A rail worker protection system having a first device configured to generate and send an identification code, a second device configured to transmit a request to the first device and to transmit a signal to one or more remote devices, and the remote device able to issue alarms to rail workers upon reception of the signal from the second device.

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.
