The invention provides a novel railway rail joint, which aims at the problems that the prior railway rail joints in China are high in friction and noise, affects train speed, and the like because of plane-to-plane connection. The invention provides the novel railway rail joint, which changes partial rail head (1) of an I-shaped rail in contact with wheels from a plane into two tenon shape joints with one side convex and the other side concave, namely an 'N' shape, and does not change a middle rail web (2) or a bottom (3). When the rail is laid, any two joints are aligned, and a steel plate (5) is placed in the two joints and fixed by screws (4). The joint can also be changed into a miter joints at an angle of 30 to 60 degrees. The railway rail joint can reduce the friction between train wheels and the rail joint, and has the advantages of raising the running speed of trains, reducing train noise and the like.
