Summary

The Datong-Qinhuangdao heavy haul railway located in the north of China carries the largest freight traffic in the world. Nearly one thousand guard rails for turnouts need to be replaced due to the poor wear resistance of the existing heat treated rails. In this paper, laboratory research and industrial trials of high strength alloy guard rails have been carried out to solve the problems in manufacturing and the use of guard rails in China. A comparison of alloy guard rails and the heat treated rails provides data on the difference in hardness. Two years of field tests on the Datong-Qinhuangdao heavy haul railway show that, the service life of the high strength alloy guard rail is about three to four times that of existing ones. The workload of the permanent owners and the costs in maintenance and replacing would be significantly reduced.
