The tribological characterisation of rail steels has been carried out using rolling-sliding testing device with cylindrical samples with functional geometries. The test can be considered in accordance with the similar one prescribed by the GOST normative. Two steel grade, R260 and K76 Φ have been used for the laboratory characterisation. Wear curves have been carried out and elaborated depending on the in service conditions and wear amounts of the rail. The test is suitable for the comparative wear analysis of rail steels. The experimental results were compared with the curves from scientific and technological literature and with values measured from in service rails to be validated.
