    摘要： A system, method, and apparatus for detecting and reporting track defects while a train is in motion on railway tracks includes at least one defect sensor configured to sense an acceleration of at least a portion of the train; and at least one computer-readable medium. The at least one computer-readable medium comprises program instructions that, when executed by at least one processor, cause the at least one processor to: detect, while the train is in motion on the railway tracks, at least one track defect in the railway tracks based at least partially on the acceleration of the at least a portion of the train; and generate track defect data based at least partially on a location of the train when the at least one track defect is detected.

    摘要： A system and methods with which changes in microstructure properties such as grain size, grain elongation, texture, and porosity of materials can be determined and monitored over time to assess conditions such as stress and defects. An example system includes a number of ultrasonic transducers configured to transmit ultrasonic waves towards a target region on a specimen, a voltage source configured to excite the first and second ultrasonic transducers, and a processor configured to determine one or more properties of the specimen.

    摘要： Geo-defect repair modeling is provided. A method includes logically dividing a railroad network according to spatial and temporal dimensions with respect to historical data collected. The spatial dimensions include line segments of a specified length and the temporal dimensions include inspection run data for inspections performed for each of the line segments over a period of time. The method also includes creating a track deterioration model from the historical data, identifying geo-defects occurring at each inspection run from the track deterioration model, calculating a track deterioration condition from the track deterioration model by analyzing quantified changes in the geo-defects measured at each inspection run, and calculating a derailment risk based on track conditions determined from the inspection run data and the track deterioration condition. The method further includes determining a repair decision for each of the geo-defects based on the derailment risk and costs associated with previous comparable repairs.

    摘要： A rail cant measurement tool and associated methods enable users to measure rail cant. The measurement tool comprises a reference assembly, and a cant angle measurement assembly. The reference assembly comprises a track plane reference bar.The cant angle measurement assembly comprises a web-engaging arm assembly, a spring-biased lock-release mechanism, a rail cant indicator, and a rail cant linear adjustment mechanism. The web-engaging arm assembly comprises pivot arms and web rollers. The pivot arms each comprise upper arm ends and lower arm ends. The upper arm ends are attached to the lock-release mechanism. The reference bar engages opposed rails and the cant angle measurement assembly engages a select rail of the opposed rails. The rail cant indicator indicates rail cant information as determined from the track reference plane and the running surface of the select rail.
