Study of the Durability of Materials Used in Turnout Crossings

Studies of the durability of heavily loaded crossings in Latvian Railway provide information about the use of innovative materials and the impact of geometric improvements on their design. An empiric connection has been found on the basis of experimental results which enables making forecasts as to the service life of crossings. The experience thus acquired enables railway infrastructure to select crossings of the proper design more efficiently, thereby reducing life-cycle costs
