Rail joints, sometimes also called Fish plate, are an important component of rail track system to connect two rail tracks together. In common life, there are three different types of rail joints mostly used:
Drum kits joints
Compromise joints
Insulated joints
As a rail joint, the bolted joints are usually used to join rail tracks together before the are welded. As to joining two rails with differing sections, the compromise joints are mostly used. And the insulated joints are always used as the bonded or non-bonded joints. Although the perform of these three types of rail joints is different, 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 during the trains are running.
Today the world-wide famous insulated rail joints are Bonded insulated rail joints and Polyurethane insulated rail joints.
