A laterally movable ultrasound transducer, comprising the sensor of a rail fault detection device, is automatically centered on the rail as the detection device moves along the rail. The sensor includes a pair of ultrasound receiving transducers positioned to either side of a transducer which generates and receives ultrasonic energy. Signals provided by the receiving transducers are compared and any difference therebetween employed to control the lateral position of the sensor with respect to the rail.
