Abstract
This article suggests that the market for freight cars will continue to be brisk in 2006 if the first quarter of the year is any indication. Last year’s new-car acquisitions totaled more than 68,000, the largest since 1999 and an increase of 46.4 percent over 2004’s total. During the first quarter of 2006, rail-car deliveries totaled 18,542. If that pace continues, there could be more than 74,000 cars delivered this year. The reasons for the run on rail cars include a relatively good U.S. economy, growth in the intermodal, coal and merchandise segments of the market, and more truck-to-rail diversions. Ethanol production has also led to a surge in orders. Included in the Fleet Stats ’06 are the following statistics: 1) selected car fleet data; 2) railroad car owners; 3) private car owners; 4) changes in the U.S. freight car fleet; 5) U.S. freight cars by type and age; and, 6) Class I locomotives.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
