Abstract

fetched live from OpenAlex

This annual passenger rail review provides facts and figures on 34 rail transit agencies. It begins with a section on transit trends, including charts and tables showing a variety of statistics, such as rail expenses by mode, 10 largest transit agencies ranked by unlinked passenger trip, rail route mileage and status of future projects, rail routes under construction, and average weekday unlinked passenger trips by mode. This is followed by a directory arranged alphabetically by state, and includes one entry for Canada. For each agency listed, information is given regarding when service began, route miles, rolling stock, annual ridership, annual operating and capital costs, and number of stations. An overview of current activities is also included.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
