Steel rail is very important for both trains and high-speed rail. If there is a problem with the steel rails, at a small scale, it will affect the overall operation of the train. If at a larger scale, the train may deviate from the track or even have other major problems. In order to avoid this situation, railway companies also attach great importance to the maintenance of rails. Under normal circumstances, patrolling railways will have special personnel.
If some sections of the steel rail are inspected and the rail is unstable, the staff will carry out reinforcement. If the rails are really broken, the only way is to replace the parts. There are a large number of parts in the maintenance warehouse of the railway company, and these parts are all section by section, and it does not require much manpower to replace the steel rail track. There are special automatic track replacement vehicles for maintenance. Because of the strong logistical support, even if there are problems with the steel rail, they can be solved in a short time. It will not affect the operation and traffic of the train.
Of course, the above situation can only be used when the problem is relatively simple and the handling is relatively smooth. Sometimes when workers inspect the steel rail, they will find that some parts cannot be replaced in time. Then they can only deal with it by welding. The workers will perform aluminothermic welding on the faulty parts of the rails. This method is not very difficult, and the welded rails also have high firmness. This method is also a method commonly used in the vast railways.
