Welded crossings are now introduced on IR recently.. These crossings are built up by welding suitably machined rail pieces and in some cases enclosing a piece of high strength wear resistant steel bar between the running rails. The latter type, manufacture according to the patented process of M/s. Henry Boot of U.K., is planned for trial on Indian Railways. These crossings with less of loose parts and made out of tougher steel, are expected to give much longer service life in track.
