Abstract

The most common types of rail defects on modern railway lines occur due to the rolling contact fatigue of rail steel. One of the methods to slow down the development of these rail defects is the application of new steel grades with increased hardness in curves of the larger radii and other characteristic track sections. Serbian standard SRPS EN 13674-1:2017 - Railway applications - Track - Rails - Part 1: Vignole rails 46 kg/m and above - comprises nine types of perlite rail steel with hardness from 200 to 440 HBW. Infrastructure Managers were increasingly applying rail steel hardnesses ≥ 350 HBW in order to extend the life cycle of the rails in the track. The paper presents UIC recommendations regarding the application of rail steel quality based on the results of the latest research and practical experience.
