European railways established the Euro-Norm EN 13231 "Railway applications — Track — Acceptance of works" in 2006. Part 3 of this standard, which was developed by the European Committee for Standardization (CEN), deals with the "Acceptance of rail grinding, milling and planing work in track."
Grinding Practices Earlier generation rail grinders were fitted with fixed grinding motors that required many grinding passes to remove short-pitch and short-wave corrugations, and improve rail surface conditions. Today, modern rail grinding equipment can achieve the desired rail profile and surface condition in a single pass.
Grinding shaves off the top surface of the rail, removing the cracks before they have a chance to propagate down into the web and thus preventing rail breaks. A study by the European Commission suggests that RCF management is a costly …
