| Summary: | been consolidated resulting in the elimination of redundant damage. In this study, a model for optimizing a grinding defects is proposed. The model includes a statistical defects, one potential cause of train derailment. The experienced a significant increase in heavy axle loads acting grinding. Current rail grinding practices involve removal of increase in the rate of occurrence of rail head fatigue involve grinding as a means to mitigate internal fatigue on railroad rails. In addition, railroad operations have Over the last two decades, the railroad industry has primary form of maintenance employed by the individual rail head fatigue analysis, and optimization of a grinding rail. railroads to combat the formation of fatigue defects is rail representation of wheel loads, a rail head stress analysis, a routes and increased train traffic on the remaining routes. schedule via mathematical programming. Results from using schedule which will prevent the formation of internal fatigue such a way as to double the useful service life of railroad surface defects and reshaping worn rail, but they do not These changes in railroad industry practice have caused an this model indicate that rail grinding might be performed in |
