Scrap rail is actually the floorboard of scrap rail and old rail. Scrap rail can not be reused, but can only be recycled as heavy scrap steel in iron and steel enterprises. Old rails can be made of steel, most of which are of fixed length. The general purpose is that the railway department can replace the rail first according to the wear degree of the rail and can reuse it. Enterprises that use old rails are generally enterprises that need to lay rails in tunnels, such as coal mines, and install gantry cranes and crown blocks. They also need old rails, which can save a lot of costs compared with new rails, and the use effect can be said to be the same.

In one case, scrap rails can be used as cheap rails for disposable lines, or they can be used as slide rails. Many warehouses in large heavy industrial enterprises use scrap rails as sliding rails. Because their prices are not high, their shapes are also very suitable for making summer sleeping mats, their buttocks are big, they are familiar with each other, there is a certain height difference from the ground, and their shapes are flat. After they are put on, they will not worry about the goods falling down like logs.

There is also a case of remanufacturing, because there are still some hidden dangers when the worn waste rails are reused in the production line, and they can be reprocessed into useful steel equipment to respond to the recycling of national resources.
