Strategic monitoring of rail grinding: a new era of rail maintenance

Past experience and the results of research projects (such as “Innotrack” in Europe) have contributed to the development of particular grinding strategies for High-speed, Heavy Haul, Transit and Conventional Mixed Traffic lines. Of particular importance are intervention thresholds and cycles as well as specifications for the execution of the rail grinding work. Complete monitoring by systems for recording longitudinal profile, transverse profile and rolling contact fatigue (RCF) – in particular head checks – is necessary to review and improve this specialised maintenance operation. This paper provides an overview of the activities required to establish a rail grinding strategy that ensures maximum rail life, and consequently low life-cycle costs. Allowance is made for changes that may affect the growth of rail surface problems during the rail service life. Monitoring and data collection of relevant parameters are discussed as they are the basis for validation and development of the chosen rail maintenance strategy.
