Railway fish plate, it is also called rail joint or joint bar. As one of the rail components, rail joint's function is different from other rail components. Rail joint is a flat metal plate usually used to connect adjacent two rails by a number of rail bolts or railroad spikes. Traditionally, railway fish plate is drilled with some holes on the ends of the sections to be connected. There are some holes in the end of railway track, which are used to be lined up with the holes in the railway fish plate and jointed with rail bolt. In general, railway fish plates are made of steel, but plastics and composites are alternative raw materials for rail joint.
