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.
Railway fish plates Applications:
Railway fish plates are widely used in heavy rail, light rail and crane rails, for different standards of steel rails, railway fish plates varies. We can produce more than 30 types of railway fish plates according to different standards:
Railway fish plates for light rail: 8kg, 9kg, 12kg, 15kg, 18kg, 22kg, 24kg and 30kg
Railway fish plates for heavy rail: 38kg, 43kg, 50kg and 60kg
Railway fish plates for crane rail: QU70, QU80, QU100 and QU120
Types railway fish plates:
In rail track system, railway fish plates are important components to joint two steel rails together. In a real world application, there are three commonly used types of railway fish plates:
1. Bolted joints
2. Compromise joints
3. Insulated joints
For railway fish plate, the bolted joints are usually used to join steel rails together before they are welded. As to joining two steel rails with differing sections, the compromise joints are mostly used. And the insulated rail joints are always used as the bonded or non-bonded joints.
Although the performances of these three types of rail joints are not the same, they still have many similar
features:
Bolts and bars are all used and a discontinuity is created on the running surface of the rail track
The discontinuity can accelerate track degradation around the rail joints while trains are running
