Nowadays, trains are an important means for traveling. The speed of trains has been increasing. For example, in Germany, a third generation high-speed train currently in service runs at 330km/h in normal operation. In China, with rapid economic growth in recent years, train speed is increasing time after time. For the Beijing-Shanghai high-speed railroad which is currently under construction, the design speed is up to 300km/h. As the train is going faster, more concern is given to the safe operation of trains and higher performance and quality are required for parts used in train. This paper provides a new electromagnetic acoustic technique for testing of in-service railroad wheels and discusses its technical features, advantages and future application versus conventional testing techniques. As the train speed increases, better safety of train is required. Frequent monitoring of in-service railroad wheels is very important to avoid potential accidents. It is said that there are several tens of train repair plants and several hundreds of depots in China. To use automatic EMA technique for testing of in-service wheel treads, especially for automatic testing as the train runs into the garage, will greatly help to early identify and correct wheels of poor quality and avoid potential accidents.
