A method of detecting damage in a rail (14, 16) includes the step of running a vehicle on the rail, detecting the sound produced by the rail (14, 16) as a result of the vehicle running on the rail and analysing the detected sound to provide an indication of any damage to the rail. Alternatively or additionally, the light reflected by the rail (including laser light directed at the rail) and/or the temperature of the rail may be detected. The method is particularly aimed at detecting complete breaks in rails. The method may be carried out while the train is operating a normal commercial service, thus minimising disruption and providing continuous analysis of the condition of the rail network.
