FATIGUE STRENGTH TESTS ON RAILS
Fatigue strength data on rails have seldom been published. Japanese National Railways, in connection with the adoption of long rails (0.5, 1.0, 1.5 or 2.0 km) and speed-up of train operation, is vigorously pushing fatigue strength investigations as well as qualitative study of rails. Soundness of the welded rail is hard to evaluate through a mere external inspection; therefore, nondestructive testing methods such as ultrasonic, magnetic detection and mechanical methods such as static bending, repeated drop weight should be coupled with it. Present demand is to secure a sound welded rail in the field through fatigue strength comparison between the base metal of rail and the welded joint.
