Understanding Why, When and How Rail Grinding is Performed

• Key role of grinding is to control and remove rail surface defects – Grinding templates and patterns to address class of defects • NOT ALL DEFECTS HAVE TO BE COMPLETELY REMOVED • Important to know when to stop grinding – Do not want to grind away all of the work hardened rail head – Grinding on a regular cycle allows for long term defect control
