Summary

A methodology for the assessment of material degradation and rolling contact fatigue of rail profiles in switches & crossings have been developed over the last 10 years and set into operation. The methodology incorporates testing on a test stand with modified input data and on a regular track section under operating conditions. The assessment of the material behaviour performed using a special test frog on the test stand using a frog of the type EH 60-500-1:12 installed in the track. Pearlitic steel grades with different material compositions, bainitic steel grades and a typical manganese (Mn 13) steel without an explosion hardened surface were compared to the standard steel grade R 350HT.
