RCF IRREGULARITIES ON THE RAIL HEAD – GUIDELINES FOR MAINTENANCE

Abstract

The focus of the paper is on defining clear guidelines for the identification, monitoring, and management of these phenomena with the goal of extending the service life of both railway infrastructure and rolling stock, while also improving the overall efficiency of the maintenance system. The management of rail defects is approached as an integral part of both track superstructure and substructure maintenance systems. Modern non-destructive testing methods are recommended for rail inspection, including ultrasonic and eddy current techniques, which allow for the detection of internal and surface flaws without damaging the material. Control of defect development involves the use of grinding, rail head reprofiling, lubrication on curved track sections, and timely rail replacement in cases where the risk of fracture becomes critical. Special attention is given to dangerous combinations of multiple fatigue-related defects, which can significantly increase the risk of sudden failure. The paper contributes to the advancement of predictive and preventive maintenance strategies in modern railway systems.
