More DetailsAverage grinding performance depends on the type and size of rail defects to be eliminated, the quality of grinding wheels and on the hardness of the rails. As a reference value for clean running surface grinding, in case of max. 0.2 mm corrugation wear depth and normal R220 (MSZ EN 13674) quality rails it is possible to achieve 0.2 mm grinding depth in one run and appr. 250 track meter/hour.

More Detailsii Abstract Grinding of rails is a technique widely used within the railway industry to balance the degradation of the condition of the rail with the required performance of the rail. The principal focus of this research is the impact of wear and rolling contact fatigue (RCF)
More DetailsRail grinding continues to be one of the most effective techniques for extending rail life, improving wheel/rail contact behavior, and reducing the overall cost of track maintenance. While the ability to more effectively implement improved rail grinding programs continues to expand, the understanding of the grinding mechanism itself has not kept pace with the improved implementation.
More Details· Since actually grinding the rail would require much more logic in terms of input, I probably won''t be posting it here unless I have tons of free time, Which honestly, I kind of do… Note: I have tested the script for simple rail generation, but I have not tested any portion of the branch solution script, since I didn''t make a GrindRail function for it.
