Abstract
To support the decarbonization of inter-city transport and reduce the risk of marginalized populations being excluded from long-distance travel, intra-city transit systems should provide equitable access to inter-city rail network nodes. This study evaluates transit-based accessibility to inter-city rail stations in seven Canadian cities along the Québec City–Windsor corridor through an equity lens. Specifically, we evaluate accessibility inequalities using Gini coefficients and three accessibility ratios based on income, race, and age. While Gini coefficients reveal no clear link between city size and inequality, the three socioeconomic status-based accessibility ratios indicate that marginalized population groups face significant inequalities in the two largest cities: Toronto and Montréal. In these two cities, low-income individuals, visible minorities, and older citizens experience inequitable accessibility, with longer transit travel times to inter-city rail stations. These findings highlight the uneven distribution of transit access to inter-city rail services in larger cities, potentially deepening social exclusion for vulnerable population groups and hindering the transition to sustainable inter-city travel. By examining intra-city transit access to inter-city rail through a social equity lens, this study offers valuable insights into the social equity of intermodal connectivity in Canada and provides a framework for similar assessments in other geographic contexts.

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
