During service, the rail will be impacted by the vertical, horizontal, and longitudinal loads of the wheels, which will cause damage, cracks, and breaks at different parts of the rail head and inside the rail, as below.

If these injuries are not dealt with and effectively controlled in time, they will affect and limit the rail service performance and shorten its service life, which will bring high maintenance costs.

Grinding is an effective means to prevent and repair rail damage, which is mainly divided into three types: pre- grinding, preventive grinding, and repair grinding.

Figure 2 shows the service life of rail injuries regarding unground, reparative, and preventive grinding.
