Types of Rail Joints

May. 10, 2021

The rail joint bars described, also called railway fish plate or rail fish plate. As an important accessory used in railway construction, the rail joint is mainly used to connect rails between railways. It plays the role of a fixed rail during train operation, thus maintaining the continuity and integrity of the track. With the increase in railway speed and carrying capacity, as well as the popularity of high-speed railways, the performance requirements for rail joints are becoming higher and higher. At the same time, there are various types of rail joints, such as insulated rail joints and eclectic connecting rods.

Rail Joints Bars

What is an insulated rail joint?

Normally, rail joints are made of metal. Insulated rail joints are made entirely of insulating materials. Insulated rail joints are a new type of rail material made of high-strength composite material. It is corrosion-resistant, rust-proof, UV resistant, non-conductive, and non-magnetic. It is a thermosetting material that cannot be treated twice and is therefore not afraid of theft.

 

Insulated rail connectors connect the ends of the rails. The rails should not be significantly bent and twisted after rolling. For local bending and twisting of light and heavy rails and the amount of their correction, the inclination of the rail ends shall not exceed the standard. The surface of the rails shall be clean and smooth, without defects such as cracks, crusts, or scratches; there shall be no signs of shrinkage or inclusions on the end face. The degree and a geometric number of defects allowed on the entire surface of light and heavy rails shall not exceed the standard.


Types of rail joints

Slip rail joints are widely used to join two sliding rails together and to ensure the safe passage of trains on the track. Depending on the position of the rail sleeper, rail joints can be divided into three types: support joints, overhanging joints, and bridge joints.

Support joints

Rail joints in railway tracks where the rail sleepers are located directly under the rail end. On the one hand, by supporting the rail joint, wear and tear on the rail can be reduced. On the other hand, even if the support may slightly raise the height of the tail end, this support joint makes it difficult for the joint to move.

Cantilever joints

Railway joints are located between two railway sleepers and where a part of the railway cantilever is at the joint. Due to the cantilevering effect alone, the joint becomes loose due to the hammering effect of the transmitted trainload. Suspension joints are widely used in railway systems all over the world, especially in India.

Bridge joints

Railway joints are similar to suspension joints. In contrast to suspension joints, a bridge joint is connected on either side by a metal flat plate or a corrugated plate called a bridge plate. This type of joint is not commonly used on Indian Railways.


Rail joints and fasteners

A rail joint can also be referred to as one of the rail fasteners. When using rail joints, a number of other fixings are essential, such as fish bolts, rail nuts, and washers. In addition to bolts and nuts, the
