What if the rail shoulder is worn

First, grinding repair
For a small amount of shallow rail shoulder wear, it can be repaired by grinding. In this method, the surface of the worn rail shoulder is polished mechanically or manually to remove the wear layer and restore the smoothness and contour of the track. After grinding, the service life of the rail shoulder can be extended and the operating conditions of the train can be improved.

Second, welding repair
If the shoulder wear is serious, it may need to be repaired by welding. Welding repair can completely restore the shape and size of the rail shoulder, improve the strength and stability of the track. Welding repair requires professional technicians and equipment to ensure welding quality and safety. During the welding process, it is necessary to control the welding temperature and welding speed to avoid secondary damage to the track.

Three, replace the rail shoulder
If the shoulder wear has reached the point where it cannot be repaired, or the repair cost is too high, you can consider replacing the shoulder. To replace the rail shoulder, you need to remove the old rail shoulder first, and then install the new rail shoulder. During the replacement process, it is necessary to ensure that the material, specifications and performance of the new rail shoulder meet the design requirements and work closely with the other parts of the track. Replacing the rail shoulder can restore the integrity and stability of the track and improve the safety and comfort of the train.

Four, glue repair
In recent years, glue repair, as an innovative solution, has also been applied to the maintenance of railway tracks. For the repair of rail shoulder wear, special glue with very high adhesion and wear resistance can be used. This glue can penetrate into the tiny gaps in the shoulder of the rail, binding loose sand, gravel and other impurities to the surface of the track, forming a solid protective layer. When using glue to repair, you need to clean the surface of the rail shoulder first, remove impurities and oil, and then evenly apply the glue and wait for it to cure. The glue repair method is simple and easy, the cost is relatively low, and the maintenance time can be greatly shortened.
