This article discusses the use of a Grinding Quality Index (GQI) for assessing the effectiveness of rail grinding. The GQI is essentially an indicator of the degree of difference between the actual rail profile and the desired rail profile. These profiles are a function of grinding approach and the location. By comparing these pre- and post-grind figures, the effectiveness of the rail grinding treatment can be determined. High-accuracy, laser-based measurement systems are used to determine rail profiles. These tools examine the “after” rail head profiles that are ground into the rail head and compare them with the desired profile. The article details how the GQI can also be used for grinding planning and prioritization. Recent experience using the GQI is also discussed
