Railway Fish Plate

railway fish plate

Rail Fish plate, also known as Rail Joint, joint bar, splice bar or angle bar. It’s to connect the end of two rails, and reduce the impact of wheels to the jointing sections of the rail tracks and increase the continuity and steadiness of the train when it pass through the jointing sections.

How does it work?

Rail fishplates are usually 600 mm (2 ft) long, used in pairs either side of the rail ends and bolted together (usually four, but sometimes six bolts per joint). The bolts may be oppositely-oriented so that in the event of a derailment and a wheel flange striking the joint, only some of the bolts will be sheared, reducing the likelihood of the rails misaligning with each other and exacerbating the seriousness of the derailment.
