This paper deals with the design and operational results of an ultrasonic inspection system specifically designed to detect, in a reliable and repetitive way, the cracks that may develop in train wheels around the brake disk mounting drills. The inspection system described throughout this work, designed to inspect train wheels for cracks developed around the brake-mounting drills, is currently being used by ALSTOM in its maintenance facilities in Barcelona, Spain, for the regular inspection of commuter train wheels, and has been certified by RENFE, the Spanish railroad services operator, as the approved standard for train wheel inspection. It must be noted that this is not a laboratory method, but a complete industrial inspection system that provides efficient and reliable crack detection covering the complete drill area without taking apart the wheel from the train, something impossible to achieve with a conventional system. The static, automated version of the system, cuts down wheel inspection time to only 2 hours per train.
