Compromise Joint Bar ( Compromise Fishplate)

Compromise joint bar is a type of non-standard fish plate consisting of two separate bars- an outside joint bar and an inside joint bar, these bars are designed to smoothly match the gauge-head face of two rails. Each compromise joint bar will provide proper alignment of rails on gauge line and top of head and prevent excessive wear at the joint.

Compromise Fish Plates(Bridge-shaped Rail fish plate), with screw holes in the middle, upper and lower sides along the horizontal axis of the screw holes are provided with upper working surfaces that are in contact with the lower part of the rail head, and a lower part that is in contact with the upper part of the rail bottom. In the working face, the rear part of the upper working face extends upward to form a transition section higher than the rail surface, and the transition section forms a bridge arch shape with a middle height and low ends along the length direction of the fishplate. The bridge-shaped rail joint bar has a simple structure, which can reduce the impact of wheels on the rail joint, increase the continuity of the longitudinal deformation of the rail at the joint, and improve the smoothness of the train when passing through.
In order to ensure the overall safety of railway turnouts, it is composed of the safety of each component. Therefore, although the fishplate is small, it plays a large role in railway turnouts. For the normal operation of railway turnouts, it is necessary to inspect and maintenance on the railway rail fish plates.
