Abstract
A method for assessing contamination of a rail, in particular for a railway vehicle, comprises the steps of imposing a first sliding value lower than a first threshold between the wheels of a first controlled axle and the rail, the first controlled axle being the head axle of the railway vehicle, imposing a second sliding value greater than a second threshold between the wheels of a second controlled axle and the rail, the second axle following the first axle and the second threshold being greater than the first threshold, and determining the trend of an adhesion curve between the wheels belonging to a plurality of controlled axles and the rail, based on a first adhesion value between the wheels of the first axle and the rail, and a second adhesion value between the wheels of the second axle and the rail.
