Аннотация

Rail joints are use for the purpose of joining the two rails. Due to large number of drawbacks and for safety purpose the number of joint in mainline track has been minimized by the widespread use of continuously welded rail (CWR) .For automated block signaling it is required to have sections of track electrically insulated from each other, disallowing the rail to be continuously welded as is done where possible ,this joint is called as insulated rail joint(IRJ).The IRJ is however substantially weaker than the rail and so is subjected to large stresses, causing failure. This paper is part of study into various stresses develop in various components of IRJ and future scope in it so that performance of assembly can be improve.
