Abstract
Fuel savings can create huge economies for railroads, which are increasingly aggressive as diesel prices continue to rise. For every dollar added to a barrel of fuel, it costs a railroad the size of Canadian Pacific $10 million off the bottom line. Railroad mechanical, transportation and financial planners are taking steps to cut fuel use. They include stop/start devices on locomotives, enforcing stricter operating rules, and locking in lower, fixed fuel prices. Burlington Northern recently instituted a cross-departmental fuel conservation team to discuss, critique and share ideas on fuel conservation practices and use. They expect to achieve a 2% increase in efficiency. For every penny per gallon it saves on fuel, the railroad saves $13 million annually. This article describes shutdown/startup systems used to cut fuel used during idling. Another approach is to analyze operating practices for more efficient fuel use. Also, replacing locomotive fleets with newer, more efficient models can cut costs. Hedging fuel can lock in supplies at predictable prices, enabling better planning.

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
