Abstract: The present invention relates to a device for detecting defects in a rail, including at least one collection of sensors which are able to generate an electrical signal indicative of a distance (dn,i) separating the sensors and the rail, and at least one rail vehicle able to move along the rail; the collection of sensors being assembled to the rail vehicle; the rail vehicle being configured to rest on the rail in such a way that said sensors are positioned facing and some distance away from said rail. The device includes a friction pad comprising a lower surface able to slide along the rail, the friction pad further comprising at least one cavity formed in the lower surface, the at least one collection of sensors being housed in the cavity.
