Wheel – rail friction is a basic phenomenon that enables railway transport running. That friction is accompanied by a wear, that determines wheels durability and reliability. Wear influences strongly the railway transport safety. Wear of railway wheels depends on their working conditions and also on their material. In this paper results of laboratory tests that simulated tribological pair wheel flange – rail side have been presented. The results enabled to determine the influence of selected working conditions i.e. load, sliding distance and velocity, and also material parameters such as chemical composition and hardness on the wear of simulated pair.
