Summary

This paper shows the development of an ultrasonic testing method to inspect for rail transverse cracks in the presence of horizontal cracking. First, we tested arrangements for the position of probes on the railhead to detect this type of rail flaw. We developed a new method to inspect from the underside of the railhead with conventional ultrasonic method. But this method cannot be conducted without stopping or automatically. So we applied phased array method to the previous developed method. This method consists of two phased array probes beneath both side of the rail crown. Ultrasonic waves are transmitted from the transducer on one side to the transverse crack, in a V-shaped route, on to the receiver on the other side. This can detect transverse cracks without being disturbed by horizontal cracks.
