Understanding Why, When and How Rail Grinding is Performed

• WHY GRIND – Wheel/Rail Contact – Wheel/Rail Surface Defects – Broken Wheel Mark on Rail • HOW AND WHEN – Philosophy of Grinding – Development of Templates – Surface Crack Measurement – Grinding Plan Development – Grinding Quality Control – Educating Different Departments 2Rail grinding philosophy has evolved in the last few decades to reflect the changing needs of modern railroads and to take advantage of new technologies New maintenance considerations have been developed to deal with increased train weights, higher tonnage, new types of rail Railroad Maintenance: Rail GrindingMay 27, 2017 Rail grinding is the most effective way to maintain steel rail Known from the railway track working principle, railway actually provides a continuous and elastic foundation for train operation As the main part of railway track system, steel rail directly attach wheel bear a lot load from trainHow Much Do You Know About Rail Grinding? AGICO RailRail grinding is 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 experience corrugation and overall wearRailgrinder WikipediaFeb 14, 2014 3  Rail Grinding is an important track maintenance tool  Rail Grinding is the removal of metal from the surface of the rail head  Through the action of a rotating grinding wheel  Mechanism used in rail grinding is cutting of metal associated with formation of metal chips (and not metal deformation)Rail Grinding Machine:A Basic approach SlideShare
