Railway Fastening Fish Plate

Railway Fastening Fish Plate

Railway fish plate, also called rail joint or splice bar, is a metal bar connected to the ends of two railroad rails to join them together. By experience, high quality railway fish plates can effectively reduce the influence of wheels to the jointing sections of the steel rail and increase the steadiness and continuity of the train when passing through the jointing sections. As an important part of rail components, railway fish plates are widely used both in light rail and heavy rail to guarantee the safety of railroad transportation.
