This document 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.<\/p>\n
\nNOTE Grooved rails are also used for harbour and industrial tracks.<\/p>\n<\/blockquote>\n
Five 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.<\/p>\n
This document specifies 26 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.<\/p>\n
Two grooved rail classes are specified differing in requirements for profile tolerances.<\/p>\n
