CONTRIBUTION TO THE THEORETICAL EXAMINATION AND EXPERIMENTAL TESTING OF RAILS

EIN BEITRAG ZUR THEORETISCHEN UNTERSUCHUNG UND EXPERIMENTALLEN PRUEFUNG VON EISENBAHNSCHIENEN

The forces acting on rails under different conditions of service stress were calculated. Calculations were compared with results of fatigue tests on S49 and UIC60 rails. The variables investigated for their specific effects included locomotives vs freight cars and fast succession of trains. Fracture formation and propagation are discussed. It is concluded that high axle loads require a large rail section, and small wheel diameters also require a high tensile rail steel. The UIC60 rail of steel with 900 N/mm2 minimum tensile strength meets the two requirements and offers ample reserves.
