Interface impact sound-free steel rail

Provided is an interface impact sound-free steel rail which comprises a steel rail body, an inclined end surface joint I is welded at one end of the steel rail body; an inclined end surface joint II is welded at the other end of the steel rail body; bodies of the inclined end surface joint I and the inclined end surface joint II are inverted T-shaped steel; the width of a vertical plate of the inverted-T-shaped steel is the same as that of a rail head of the steel rail body, a bottom plate of the inverted-T-shaped steel is the same as the rail bottom of the steel rail body, and the end face ofthe inclined end surface connector I is parallel to the end face of the inclined end surface connector II and perpendicular to the plane where the rail bottom of the steel rail body is located. Compared with the prior art, the guide rail laid by the invention has the advantages that when a train wheel rolls on the previous steel rail, the train wheel rolls up and down the previous steel rail, sothat the seamless-connecti
