Railway applications - Track - Rail - Part 2: Switch and crossing rails used in conjunction with Vignole railway rails 46 kg/m and above
This document specifies switch and crossing rails that carry railway wheels. These are used in conjunction with Vignole railway rails. This document is not applicable for the check rails that do not carry railway wheels. Nine pearlitic steel grades are specified covering a hardness range of 200 HBW to 410 HBW and include non-heat treated non-alloy steels, non-heat treated alloy steels, heat treated non-alloy steels, heat treated low alloy steels and heat treated alloy steels. There are 33 rail profiles specified in this standard, but they may not all be available in all steel grades. Rails specified in EN 13674-1 can also be used as switch and crossing rails and if so used they will comply with the requirements of EN 13674-1.
