This paper describes an investigation into how the mechanical properties of worn rails removed from a track system change in relation to the traffic density and the weight carried. The study also includes investigations aimed at restoring the desired characteristics of the rail heads by successive heat treatments. Impact tests were used to evaluate the effects of volume tempering of worn rails and attempts were made to establish the relationship between the operational mode and the rail head profile on impact and fatigue strengths. Suggestions are given for reducing the risk of rail damage due to various defects, including a recommendation for periodic grinding of the heads.
