  • Patent number: 11254336
    Abstract: A rail flaw detector is configured for locating flaws in rails of a railroad track and for use with a vehicle travelling on the railroad track. The detector includes at least one signal applicator configured for applying ultrasonic signals to the rail and for receiving return signals; a mechanical subsystem connected to the applicator and to the vehicle and configured for maintaining the at least one signal applicator in operational position on the track. A human-machine interface is connected to the at least one signal applicator, is configured to control the detector and to monitor sensed rail condition. In one embodiment, the human-machine interface includes a schematic display of the rail being monitored and at least one touch screen control for controlling the mechanical subsystem and the at least one signal applicator.
    Type: Grant

  • Patent number: 9981671
    Abstract: A railway inspection system for monitoring defects of a rail, including an inspection vehicle configured for traversing the rail, a sensor disposed on the vehicle configured for obtaining rail condition data, a memory disposed on the vehicle and storing previous rail condition data from a previous traversal of the rail, a display device disposed on the vehicle, a processor disposed on the vehicle and a non-transitory computer-readable medium disposed on the vehicle and containing instructions, which when executed by the processor, cause performance of the following steps in real-time as the vehicle traverses the rail, namely obtaining current rail condition data from the sensor, displaying on the display device representative images of the current rail condition data, retrieving the previous rail condition data from the memory, and displaying on the display device representative images of the previous rail condition data.
