  • Publication number: 20250354896
    Abstract: A portable device for removable attachment to a rail has a thin upper surface contoured to conform with the head of a rail, and a simulated defect in the upper surface to exert a predetermined impact load on the wheel of a rail vehicle rolling over the device on a rail. An attachment mechanism removably secures the device to a rail with the upper surface of the device covered a selected portion of the rail head.

  • Patent number: 9162691
    Abstract: A method is provided for detecting broken rail, unintentionally misaligned turnouts, and track occupancy ahead of or behind a railway vehicle traveling on a railroad track. Shunts extend between the rails at intervals along the railroad track. Each shunt has electrical signal transmission characteristics differing from those of adjacent shunts. A test unit on the railway vehicle induces a test signal in a first rail to create a track circuit in which the test signal propagates along the first rail, through at least one of the shunts, returns to the railway vehicle along the second rail, and through the wheels and axle of the railway vehicle. The test signal has electrical properties selected to interact with at least one of the shunts. The received test signal on the second rail is analyzed to identify predetermined conditions concerning the status of the railroad track.
