MEASURING STICK : CLASS 1S AIM HIGHER ON CONSISTENCY, DEPENDABILITY CURVES
Bibliographic record
Abstract
Seeking to decrease the variability of shipping times, Class I railroad operating executives are trying to establish a customer focused service paradigm. The Canadian National Railway is using a schedule approach which sets a goal for each rail car and measures performance against goals. The Burlington Northern Santa Fe develops a trip plan for each carload called a Transportation Service Plan (TSP). Norfolk Southern Railway is implementing the Thoroughbred Operating Plan (TOP) to improve transit times through redesigning the operating plan and route traffic in blocks. CSX Transportation is trying to improve consistency through Industrial Switching Excellence (ISE), getting customers involved in car moving decisions. Union Pacific is seeking service reliability improvements by continuing their Network Design Integration (NDI). Kansas City Southern Railway is developing the Management Control System (MCS), a computerized operating platform enabling the railroad to knit together shipment schedules using customer matching data.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
