Effect Of Rail Grinding On Rail Vibration & Groundborne

MODERN RAIL grinding techniques use carefully applied grinding patterns to profile the rail head and thus determine where and how wheel rail contact will occur Computer control has made possible this fine tuning of wheel rail contact geometry which reduces damage to the rail.Rail grinding has been an important component of the BNSF rail maintenance program for the last 40 years [1] The BN began grinding in the 1960’s to remove corrugation The rail surface is maintained to control contact stress and promote wheelset steering while retaining its work hardened layer to resist.
