Rail welding and manual grinding as an integral part of track maintenance and new construction Joint-welding of rail in tracks and turnouts In order to produce a seamless, continuous track, rails are welded in track, turnouts and crossings using different welding methods in the course of new construction measures or rail and turnout renewals.
Rail grinding will cause poor surface integrity when the critical grinding temperature is exceeded. To improve the grinding quality and explore the feasibility of grinding operations in rainy days, this study first investigated the surface integrity during rail grinding under wet conditions, including surface roughness, grinding burn, phase transition, residual stress, etc.

Rail Grinding and its impact on the wear of Wheels and Rails 3 2 The wheel/rail contact As the outer rail in a curve is situated higher in a curve due to canting, it is called the "high rail". The inner rail is lower than the outer rail and is therefore called the "low rail".
Rail grinding is one effective technique of railroad track repair and maintenance. By using rail grinders, rail defect material is removed and the rail profile is restored. Thus the service life of railroad track is extended. Rail defects. When talking about rail grinding, the rail defects are needed to be introduced first.
