The windblown sand erosion wear and damage behaviors of the rail materials in windblown sand environment were investigated using a windblown sand erosion wear test machine, and the erosion wear and damage mechanisms of the rail in windblown sand environment were clarified. The rolling wear and damage behaviors of the rail in windblown sand environment were studied using a wheel-rail rolling wear and contact fatigue testing machine equipped with the device of the windblown sand environment simulation, and the rolling wear and damage mechanisms of the rail in windblown sand environment were...
