  • Patent number: 11433931
    Abstract: A system and method for monitoring a track and/or rail employs one or more distance measuring imagers mounted to a railcar and directed to image the track and/or rails wherein the images are geo-tagged with location data. Geo-tagged distance measurements are processed to determine at least track gauge and/or at least rail fastener integrity. The system and method may also determine other track and/or rail integrity issues including, e.g., rail profile, rail alignment, center point dip, cross level, rail cant, wheel wear, wheel integrity, rail wear, rail defects, and/or rail temperature. The system and method may also determine when inspection and/or maintenance of the track is indicated, and provide selected records of where and/or when such inspection and/or maintenance is indicated.

  • Publication number: 20220073113
    Abstract: A system and method for detecting and measuring rail and/or track defects may comprise: an array of time-of-flight distance measuring sensors measuring distance to the rail head; wherein the distance measuring sensors are synchronized and the dimensional data therefrom is geo-tagged. A memory stores geo-tagged distance measurement data. Distance measurement data is processed to determine the dimensional data of the rail head including at least the width and the height thereof, for detecting rail wear and rail defects. Rail wear, surface defects, rail structural defects, rail fractures and cracks, and/or a gap in a rail, can be measured and detected.
