1. A system for the detection of defects in rails, the system comprising a source of ultrasonic waves for emitting ultrasonic waves onto a rail, a detector for detecting ultrasonic waves reflected or otherwise scattered by the rail or defects therein and a mist generator arranged, in use, to expose one or both of the rail and source of ultrasonic waves to a mist of liquid, thus enabling the formation of an ultrasound-transmissive interface between the rail and the source of ultrasonic waves, the system comprising a mist accelerator for accelerating the droplets forming the mist towards the rail subsequent to generation of the mist.
