Types of Rail Joints

Rail joints are widely used to connect two rails together and ensure the trains passing through safety in orbit. According to the position of the sleeper, rail joints can be classified into three types: supported joints, suspended joints and bridge joints./

On the other hand, such supporting joint makes the joint move hard even though the support may have a slightly raise the height of the rail ends.
