Railgrinder

A railgrinder (or rail grinder) is a maintenance of way vehicle or train used to restore the profile and remove irregularities from worn tracks to extend its life and to improve the ride of trains using the track. Rail grinders were developed to increase the lifespan of the tracks being serviced for rail corrugation. Rail grindingis a process that is done to stop the deformation due to use and friction on railroad tracks by removing deformations and corrosion. Railroad tracks that experience continual use are more likely to e

Understanding Why, When and How Rail Grinding is Performed

High-speed rail grinding and metal removal Railway Track

Jun 14, 2012 Since the depth of metal removal varies across the rail head as a function of the grinding motor concentration associated with a given grinding pattern, the location of maximum metal removal varies across the railhead. This is illustrated in Figure 2, where the maximum metal removal point occurs approximately 1.2 inches to the gauge-side of the

Target Profiles for Rail Grinding: A Never Ending Story

Jan 04, 2014 Rail maintenance work is a process of removing metal from the rail head at the right time and at the right place. At first, rail grinding was performed to remove surface irregularities and defects — a process that required significant metal removal. During this curative process, the transverse rail profile was of secondary importance.
