Railway Fish Plate

Railway fish plate is also known as rail joint bar, splice bar. As a rail fastener, railway fish plate is used to connect two ends of rail. The railway fish plate is easier than the rail welding, so it is widely applied rail connection. Generally, railway fish plate is used with fish bolt, the middle part of fish plate has bolt hole, An upper working surface contacting the lower part of the rail head along the upper and lower sides of the horizontal axis of the screw hole, and a lower working surface contacting the upper part of the rail bottom, the rear part of the upper working surface extending upward to form a transition section higher than the rail surface，The transition section forms a middle arch with a low intermediate arched shape along the length of the railway fishplate. The railway fish plate has a simple structure, which can reduce the impact of the wheel on the rail joint, increase the continuity of the longitudinal deformation of the rail at the joint, and improve the smoothness of the train.
