Abstract
Da-Qin line is the first coal transportation dedication line in China with total length of 653 km . Its annual volume in 2010 achieved 400 million tonnes. The train can be operated at hauling tonnage of 10,000 tons and 20,000 tonnes, 2.5 days per cycle. It runs at the highest operation density in the world. However wheel wear became a problem after the coal car axle load was increased. Therefore a special study was conducted on wheel wear for the C80B stainless steel coal gondola car with ZK6 bogie based on special operation conditions of Da-Qin line. Wheel and track wear were measured on site and interaction between wheel and track were simulated. Test data were analyzed and compared against wear wheel for heavy axle load freight cars in other foreign countries. An assessment was made on wheel wear for freight coal cars after increase of axle load, recommendations made for reducing wheel wear and recommendations for further studies provided.
