Abstract
This article describes key findings of Best Practices in Rail Grinding, produced by the National Rail Council of Canada and the American Railway Engineering and Maintenance of Way Association. It recommends that railroads move to regularly scheduled grinding, get a consensus on how much to grind and make grinding a scheduled maintenance activity, not merely dependent on whether there is a budget for it. The article describes testing of software that would allow railroads to use performance measures and other parameters to guide grinding decisions. Railroads are also automating data collection to maintain accurate grinding records. They are also investing in development of optimal rail profiles and grinding schedules. Another tool being tested is designed to monitor wheel/rail contact conditions, identify rail fatigue and develop a way to order just in time grinding.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
