what is a railroad joint?
Rail joint, in rail terminology, also called fishplate, splice bar or joint bar, is used for connecting two rail tracks together.The name is derived from fish, a wooden bar with a curved profile used to strengthen a ship's mast.The top and bottom edges are tapered inwards so the device wedges itself between the top and bottom of the rail when it is bolted into place. In rail transport modelling, a fishplate is often a small copper or nickel silver plate that slips onto both rails to provide the functions of maintaining alignment and electrical continuity. It reduces the influence of wheels to rail links section, and ensure the stability of the train running. Rail joint can be divided into three types, such as rail joints for light rail, fishplates for heavy rail and rail joints for crane rail.

Each standard rail joint of other types (bulge, compromise, insulated, glued insulated) are also available!
Compromise Rail Joint
Compromise joint bar is used for connecting two different rail sections, it can connect them exactly and make the whole track flat and smooth. The compromise rail joints we produce use high strength steel and made by advanced precise machine, it has precise specification and fit the rails exactly. A compromise is composed of two bars: gauge side joint bar and outside joint bar.
How to choose suitable compromise rail joint?
If you want to order right compromise rail joint, the specification of both rail sections and the following dimensions of rail joint you need must be clear.
A - The end of the rail to center-line of first hole.
B - Center-line of first hole, to center-line of second.
C - Center-line of second hole, to center-line of third hole (where 6-hole bars are used).
D - Diameter of bolt hole (or bolt size).
E - Elevation of bolt hole (center-line of bolt hole above base) on non-standard rail.
Joggled Rail Joint
Bulge rail joint, also called bulge rail joint, has a bulge section in the middle of the joint bar, and it can fasten the steel rails tightly. Bulge rail joint is usually used in broken welded rails or temporary repair of cracked welded rail joint with an emergency clamp. It can suit for various rail sections and enable quick and temporary repair, guaranteeing the continuous movement in rail track.
Insulated Rail Joint
Insulated rail joint are usually used for electrical resistance in railway track. It contains insulation materials wrapped or bolted around contacting surface the rail track which can control signaling and broken rail identification systems. The end post of Insulated rail joint can be classified into two types: inserted end post and glued end post.
Insulated rail joint component：
Two rail sections
One end post
Two rail joints
Six (or four) bolts, nuts & washers
Electrical insulation material sheets
