Vertical split head defects-some insights into their development and growth
A detailed study has been conducted at the Rail Infrastructure Corporation covering a wide range of aspects associated with vertical split head defects in rails, including: why the defects occur in the older rail steels and what are the factors that cause the defects to initiate and grow, assessment of the location of the defects within the rail head, the influence of various track parameters, such as sleeper type, rail type, track geometry and rail location), the analysis of the defect characteristics using finite element modelling, the wheel/rail profile relationships, the determination of the relative importance of the various influencing factors and the steps taken to minimise the occurrence and the risk level associated with the defects. The work has led to major changes in the testing procedures and required responses associated with a potentially critical rail defect type.
