- W2199979676 abstract "Rail grinding has been a standard maintenance activity for many decades. Originally applied to remove corrugation it has been developed further. Today shaping specific transverse profile of the railhead is a routine operation. Particular profiles allow to provide optimal contact conditions between wheels and rails. Thus, the contact stresses on the rail surface are minimized and cyclical rail grinding is widely applied to control rolling contact fatigue such as head checking and squats. At the beginning only rails in open track have been ground. With growing experiences and the positive results, obtained knowledge and expertise pushed further and special machines have been built. They are designed in a way to grind the complete active rail head zone also in the critical areas namely check rails, switch blades and frogs. Technical and economical benefits can be obtained by the means of reducing dynamic forces, contact stresses and vibrations. European railways are increasingly practising rail grinding in switches, which makes nowadays part of a modern track maintenance strategy, as it allows to better exploit existing track components and reduce maintenance costs due to longer component life and less intensive repair and replacement work. The paper summarizes the currant rail grinding practice, its applications and benefits and highlights the particularities of the use of the grinding technique in switches. By-works and operational aspects are described in detail." @default.
