AbstractIn 1998, BNSF started transitioning their rail from a corrective state of wear and surface fatigue back to the favored preventive state. The National Research Council of Canada developed a unique rail-grinding strategy called Preventive-Gradual to effect the transition. This strategy was shown to extend rail life through reduced wear. The rail was restored to a superior surface condition, grinder productivity increased, and cost per finished mile decreased. Techniques for managing preventive grinding programs are reviewed, and methods to optimize the preventive-gradual strategy through rail profile design, grinding pattern refinement, and determination of the optimal wear rate are presented.
