Rail joint is applied to light rail, heavy rail, and crane rail. There are holes in the middle of the fish plate for the rail bolt to screw. The top and bottom of the fish plate are made into slopes corresponding to the slope of the lower part of the railhead and the top part of the rail bottom. Thanks to the design which helps the joint bars wedge the rails, the rail joints can be bolted to the rail very tightly.

4 types of rail fishplates
Fishplate also known as rail joint bar has 4 major types: Standard Fishplate, Joggled Fishplate, Special Fishplate,
Combination/Compromised fishplate.
Standard Fishplate
The normal fish plate is the most common type, which is widely used in various kinds of rails. It is ordinarily made of medium carbon steel and high carbon steel. And there are two types of normal fish plate, four holes normal fish plates and six holes normal fish plates.
Joggled fishplate is used while rail joint maintainence or emergency repairs, it has unique shape to leave space for welding steel rails with defective. Mostly applicated in seamless steel rails, it is a necessary part in keeping rail joints safety when there is hidden danger.
Special Fishplate
The track portion to be detected has to be electrically isolated from adjoining rails so as to block the track circuit current, within its boundaries by providing Insulated rail joints or Block joints at each end of track circuit. In general Insulated rail joints or Block joints are required at the boundaries of the track circuit and at point & crossings where the polarity of track circuit is to be changed.
There are 3 types of insulated rail joints or block joints that are presently in use as given below:
- Insulated rail joint class "A"-these Insulation joints are made of special type of wood and used in yards where speed of train is slow.
- Insulated rail joint class "B"-these Insulation rail joints are made up of Nylon 66. These are also called Nylon insulated rail joint.
- Insulated rail joint class "C"-these are also called as glued insulated rail joints. Glued insulated rail joints. These are mostly used in main line for high speed trains. The glued joints are being increasingly provided on railways to avoid failures of insulation joints particularly in long welded rails. There are two types of glued joints: G3 (L) type - six bolts, G3 (S) type - four bolts.
Compromised Fishplate
Combination fishplate, also named compromised fishplate, is used to connect two different rail sections. The design is to cover the rail section at either end adequately up to the point in the centre where the rail section changes. Another design feature is the elimination of the expansion gap to give them more strength. The varying depths of the combination fishplates can be used in the rail sections, for example, 52 kg/90 R, 90 R/75 R, 75 R/60 R, etc., which provides a common top table for the two rail sections they join.
