The ultrasonic rail inspection car's flaw detection system detects internal rail flaws as the car runs along the rail and with the distance measurement system option can provide accurate detection of flaw position.
In addition to flaw detection, additional system options include sectional wear measurement utilizing the newest in image processing technology and rail corrugation measurement using lasers.
The ultrasonic rail inspection car has established an enviable record of shipments to the Japan Railways companies including the Shinkansen as well as every major private railway company.


  • Capable of high-speed ultrasonic rail inspection (40km/h).
  • Manual calibration of position based on kilometer post references for distance information. In addition, accuracy can be enhanced using the "DataDepot" System (option) which detects position data automatically.
  • Flaw data is presented in "B" scope color display in real time. Also display recognition provides results of defect type, classification and position data. Store and playback functions are also provided which enable evaluation and discrimination of natural defects and artificial "defects" such as bolt holes, etc., which results in increased reliability of test data. "A" scope display in real time is also available.
