CEN/TC 256 Railway applications
European Norm
45.080 Rails and railway components | 93.100 Construction of railways
This European Standard specifies requirements for grooved rails and associated construction rail profiles for grooved rail facilities with a linear mass of 42 kg/m and upwards for use in tram transport systems.
NOTE Grooved rails are also used for harbour and industrial tracks.
Six pearlitic steel grades are specified in a hardness range between 200 HBW and 390 HBW. The rails are either non-heat-treated or heat-treated and are made from non-alloyed (C-Mn) steel in both cases.
This standard specifies 18 specific grooved rail profiles and 7 specific construction rail profiles. The grooved rail profiles can also be used as construction elements in switches and crossings.
Two grooved rail classes are specified differing in requirements for profile tolerances.
