It's All About Height: Tunnel and Trackwork Along NS' Heartland Corridor Will Allow a Direct Route Between Chicago and Norfolk, Va., for Auto Racks and Double-Stack Freight Cars
Bibliographic record
Abstract
This article discusses the opening of the Norfolk Southern (NS) railway's Heartland corridor for auto racks and double-stack freight cars, a project that will effectively shorten the trip from Hampton Roads to Chicago by 200 miles or about one day. Also, as the corridor can now be used for double stacks, the output for the line will be doubled upon its opening. This increased business will be a boon to local regions served on the journey. This is mainly due to the increasingly difficult time operators are having making single-stack trains operate cost effectively. Construction will begin for the corridor in the second quarter of 2007 and is hoped to be completed by 2009. A number of clearance-related issues will be solved for tunnels including further excavation by square notching, lowering the tracks, or raising the ceiling.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
