Abstract
The opening of the European market for freight and passenger services has initiated the need for cross-border locomotives which fulfill the specific requirements of each country and comply with new European standards. The TRAXX locomotive platform addresses this new market with four locomotive types. Each type is configured with standard building blocks. The TRAXX platform covers both electric and diesel 4-axle locomotives. A high level of standardization allows manufacturing of all types in a single assembly line, thus also reducing manufacturing costs for small production lots. The key to the TRAXX platform is a high level of system integration. Important innovations are in the traction chain, carbody, air supply, in the development of automatic train protection (ATP) systems based on the future European standard ETCS (European Train Control System) and in system integration. Today, the TRAXX platform covers all major mainline traction needs in continental Europe with more than 1′200 locomotives so far sold. Further developments are needed to optimize the ATP systems for new and important cross-border freight corridors and to streamline the homologation procedures throughout Europe.

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.
