Abstract Lateral displacement is one of the most important case parameters in research of wheel/rail interrelation. The variation of lateral displacement affects extremely the geometry and mechanics parameters in contact zone. The paper deals with effects of lateral displacement on elasto-plastic stress field in rail head. The research shows, lateral replacement influences greatly the yield zone and the distribution of stress status in rail head.
