How to reduce the damage of new rail
Aug 07, 2017

The effective reduction of rail damage includes reducing the abrasion of curved rails, and improving the main measures is to improve the design of bogie of locomotive and vehicle so as to improve the interaction condition between wheel and rail and reduce the friction between them.

As a stopgap measure, special alloy rails with high abrasion resistance can be applied on the side of curved rails or on small radius curves. The effective method to prevent the damage of new rail is to control the cooling of the steel material, to avoid the small crack caused by hydrogen escaping inside the rail, and to eliminate the fatigue source of the nuclear wound fundamentally.

Despite all kinds of preventive measures, the new rail can not be completely avoided, in order to ensure the safety of traffic, we must carry out regular rail inspection, in order to eliminate hidden dangers and avoid major accidents.
