Abstract (en)

A method of inspecting the condition of a track used in a transport system comprises: fitting an inspection device to a transport vehicle of the transport system; and using the device to inspect the track. Aspects of the invention relate to determining track condition, in particular, but not exclusively, to crack detection in a rail (210) used by a train locomotive (200). By fitting the device to a normal transport vehicle, no dedicated engineering vehicle is required, thus leading to lower cost and greater convenience. <IMAGE>
