Improved Switch Expansion Joint

To overcome the defects caused by bend in Switch Expansion Joint the design has been modified to Improved Switch Expansion Joint. Rail movement joints are required when tracks are laid across engineering structures such as bridges and viaducts. These structures are exposed to changes in lengths due to ambient influences like traffic load, temperature and wind. These influences sometimes lead to angular rotations of the end spans in the abutment. Rail movement joints are installed to bridge such length variations and - if required - to accommodate angular rotations of the end spans.
