Understanding Why, When and How Rail Grinding is Performed

Profile Grinding Goals • Top of rail should never have a radius less than 8” – Reduced running band can result in high stresses and rail surface fatigue (spalling) – Running band should be between 1 1/4 and 1‐3/4 inch on all rails • Reduce plastic deformation and metal surface fatigue
