Shattering Conclusions: Checking for Wheel Defects on the Fly at TTCI

This article describes a new technology that is undergoing testing for inspecting defects in railcar wheels—while the cars are moving. The new method, known as the Automated Cracked Wheel Detection (ACWD) system, uses specially designed ultrasonic probes and detection algorithms to spot shattered rim cracks and tread cracks in wheels along one side of the train as it moves at four to five miles per hour. The article describes the types of cars that have been tested, and the results of visual versus the new method in finding cracks or other flaws.
