The life of rail in tunnel is very short compared with that out of the tunnel itself.A serious problem hereby is that acidic gas from steam locomotives creates a corrosive condition which attacks rail and develops cracks in rail joint areas.To solve problems of rail joint failure due to corrosion, a fatigue test was conducted by dripping on the specimen some corrosive liquidsneutral tap water or tap water+H2SO4 (pH 3.5 and 2.2). The results show that the endurance limit decreases rapidly with decreasing value of pH.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
