Indian Railways is considered as the lifeline of the nation. It fulfills vital transport necessity and large number of people travel daily on its network. The safety of the traffic is to be given paramount importance on a railway system. Lots of advancements have taken place in track infrastructure and better track maintenance practices have been evolved to improve the reliability of the system. The noteworthy among these are the conversion of free rails into long welded rails, use of pre-stressed concrete sleepers, mechanization of track maintenance, improvements in the rail manufacturing technology, improvements in the rolling stocks etc. The track structure today is sturdier and the track parameters are better maintained. This has certainly reduced the risk of accidents due to rail wheel interaction. However, discontinuity caused due to rail/ weld breakage is an area of concern for track maintenance engineers. The present paper discuss the detailed study about NDT in railway industry.
