Trouble on the tracks : Grand Trunk Railway of New England tragedies : accidents that occurred on the Montreal to Portland line of Canadian National Railways
Bibliographic record
Abstract
In the 1850s, Grand Trunk Railway, later Canadian National, was one of New England's and Canada's most important and heavily travelled railway lines It linked Canadas metropolis, Montreal -- through Vermont and New Hampshire -- with the nearest ice-free port at Portland, Maine. Despite constant upgrading, accidents did occur, some of them catastrophic. With details about four dozen such tragedies, you will learn what happened when people, vehicles, or nature decided to duel with a fully-loaded train. Discover the circumstances when a cattle train hit a mudslide ...a passenger train toppled over the bank ...two locomotives met in heavy fog that made it impossible to see ...two trains, one fully-loaded with immigrants, came towards each other on ONE track! ...the West Paris Bridge collapsed ...two double-headed freight trains collided head-on ...train hit fuel tanker truck, with ensuing explosion and fire ...a derailment toppled a chlorine tank car off a bridge onto the highway below.

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.
