(1) The steel rail after rolling should be straight without significant bending or twisting. The local bending and torsion of light and heavy rails, as well as the amount of correction deformation, and the inclination of rail end faces, shall not exceed the standard.
(2) The surface of steel rail should be clean and smooth, free of defects such as cracks, scars, and scratches. There shall be no shrinkage marks and interlayers on the end surface. The allowable defects on the overall surface of the light and heavy rail and the extent of their geometric quantities shall not exceed the standard.
During the operation of the railway, we must pay attention to the need for frequent inspection and maintenance of the railway fastener. All the problems must be within the specified range, and once the situation exceeds the specified conditions, the operation should be stopped immediately and maintenance should be carried out as soon as possible.
