A Method of Determining Rail Grinding Parameters Based On ...

Abstract. The factors affecting the economy efficiency of rail grinding and their interrelation are researched. Based on the management theory of life-cycle cost, the model of analyzing rail grinding parameters is established, the calculation method is determined, and minimizing the rail life-cycle cost is regarded as optimization objective for the optimal analysis of grinding factor.

Railgrinder - Wikipedia

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 grinding is a process that is done to stop the deformation due to use ...

The blending of theory and practice in modern rail grinding

Modern rail grinding practices have developed largely through a combination of field experience and intuitive speculation. Many theories related to crack initiation and growth have been proposed through the decades, and those concepts have been cleverly extended to the field of rail grinding to form the basis of the practice known as ‘preventive grinding’.
