Rolling marks
The rolling mark is a 5 mm thick, raised marking, which is 35 mm high and used in the rail web approximately every 2.25 m to 2.50 m. The various rail grades are indicated by a dash symbol in the area of the rolling mark. The rolling mark also includes the work mark of the manufacturer, the rolling year and the rail form (complete marking of the rail type).
1 = manufacturer (for example THYSSEN DUISBURG "TSTG", Voestalpine Austria "DO")
2 = type of steel (for example R 260)
3 = year of manufacturing (for example 2002 → 02)
4 = rail marking and the approximate weight
5 = rail profile (for example UIC 60, S 54, S 49, R 65)
