THE RAILS ON THE GERMAN FEDERATED RAILWAYS

DIE SCHIENEN DER DEUTSCHEN BUNDESBAHN

With the introduction in Germany of greater train loads and higher operating speeds, it was necessary to replace earlier rail, known as S49 with heavier rail, designated S54. Its usage is on main lines at operating speeds of 140 km/hr and tonnage in excess of 30,000 gross tons per day. Another rail, S64, is used where axle loads are in the range of 30 to 35 tons and in tunnels on German railways. Rail breakages are compared for the various rail. Qualities and properties of the steel are discussed and theoretical stress lines in the rail sections are depicted. The shape of the rail head on the newer designs was changed to provide improved contact with the profile of the wheel tread. Specific costs of rail replacements on the German Railways are given for the various rail designs.
