Abstract
The Quebec City–Windsor corridor is the busiest and most important trade and transportation corridor in Canada. The transportation sector is the second-largest contributor to greenhouse gas emissions in the country. Governments around the world, including Canada's, are considering increasing mode share by rail as a way of reducing transportation emissions. To understand whether freight mode shift is a realistic means of reducing transportation emissions, an analytical model is needed that can predict the effect of government policy on mode split. This paper presents the findings of the first such model developed for the Quebec City–Windsor Corridor. The model itself is a stated preference carrier choice model of shippers in this busy route. The model was developed by using the results of a stated preference survey undertaken in fall 2005. The survey was designed explicitly to evaluate shipper preferences for the carriage of intercity consignments, particularly their preferences for carriers that contract the services of rail companies to carry these shipments via rail. The results of the study (a) show that shippers are mistrustful of using rail to move their consignments and (b) suggest that increasing rail's share of freight transport faces tremendous challenges.

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 it
