Abstract
This article charts the history of the Pierre-Rapid City (PRC) railroad line, a line first developed in 1906 by the Chicago & North Western (C&NW). From the beginning, the 164-mile route was a difficult one: it crossed waterways and their tributaries 78 times. Weather was a hazard, the soil was often damp, the wooden trestles rotted. In 1983 C&NW filed to abandon the PRC, but Senator Larry Pressler of South Dakota fought against it and won, then negotiated a sale of the line. Dakota, Minnesota & Eastern (DM&E) bought it for $26 million, although it too had problems with the soil and rails that would not support the heavier trains. In October of 2008, Canadian Pacific (CP) purchased the line for $1.48 million. The article concludes by noting that plans by CP to pursue an extension on the Powder River Basin will depend on the Obama administration’s focus on tighter regulations of carbon emissions and the impact this may have on the coal market.

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.
