Patent number: 9994242Abstract: The present disclosure teaches inter-vehicle communications for avoiding rear collision of rail vehicles on a railroad. For example, a 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.Type: GrantFiled: October 2, 2015Date of Patent: June 12, 2018Assignee: HARSCO TECHNOLOGIES LLCInventor: Peter Michael Bartek

Patent number: 9902411Abstract: 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.Type: GrantFiled: October 2, 2015Date of Patent: February 27, 2018Assignee: HARSCO TECHNOLOGIES LLCInventors: Peter Michael Bartek, Michael Stephen Davis

Patent number: 9878729Abstract: 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.Type: GrantFiled: October 2, 2015Date of Patent: January 30, 2018Assignee: HARSCO TECHNOLOGIES LLCInventors: Peter Michael Bartek, Michael Stephen Davis

Patent number: 9850624Abstract: A device and method for the replacement of railroad ties is disclosed. The tie extends laterally under two rails and is attached to the rails via tie plates. An example rail changing machine includes a tie changing boom moveable to one side of the two rails. The tie changing boom including a gripping assembly for clamping the railroad tie. The tie changing boom is moveable between a proximate position and a distal position from the one side of the two rails to grip the tie and remove the tie from under the rails. A kicker is located on the opposite side of the rails from the tie changing boom and contacts one end of the tie to move the tie toward the tie changing boom. A pair of tie plate clamps to hold the tie plates in place when the kicker moves the tie.Type: GrantFiled: April 21, 2015Date of Patent: December 26, 2017Assignee: HARSCO TECHNOLOGIES LLCInventor: Robert R. Schrunk, III

Patent number: 9790644Abstract: A rail maintenance vehicle includes a frame, a workhead, an actuator, a pilot valve, and a throttling valve. The frame includes wheels that travel along rails. The actuator extends and retracts the workhead with respect to the frame. The pilot valve receives a fluid and controls the flow of the fluid to at least one output. The throttling valve adjusts a pressure of the fluid at an output relative to a pressure of the fluid at an input. The pilot valve and the throttle valve are coupled such that the fluid travels through the pilot valve and the throttling valve to cause the workhead to be extended or retracted.Type: GrantFiled: December 14, 2015Date of Patent: October 17, 2017Assignee: Harsco Technologies LLCInventor: Kevin Hansen
