Continous Welded Rail Application in Indian
Continuous Welded Rail (CWR) technology has been extensively adopted by Indian Railways, with dedicated rail welding factories located in key areas such as Mumbai, Meerut, and Secunderabad. The following are the overview of its application.
- Rail Welding Factories
Indian Railways operates several rail welding factories equipped with specialized machinery for butt welding steel rails into continuous lengths of up to 100 meters. These factories ensure efficient production of CWR sections to meet the demands of railway infrastructure projects.
- Reduced Noise
Welding steel rails into continuous lengths helps reduce noise generated by train operations. The elimination of gaps between rail sections ensures smoother track surfaces, contributing to a quieter travel experience for passengers and residents along railway lines.
- Fishplate Joints
Despite the use of CWR, fishplate joints are still incorporated into the track infrastructure. These joints, typically installed every 100 meters, allow for lateral expansion of the rails during hot weather conditions. They accommodate thermal expansion and contraction, ensuring track stability and safety.
