Abstract

fetched live from OpenAlex

Hamilton Street Railway, the city of Hamilton, Ontario’s public transportation system, has a long history. The system was first run by horse-drawn cars, but was electrified in 1892 — around the same time that innovation surrounding electricity transmission came to Hamilton. It consisted of various routes around the city, including the “Belt Line,” which connected the east and west ends of the city. The system, along with four interurban lines that went to Burlington, Beamsville, Dundas, and Brantford, were eventually purchased by the utility company, Dominion Power and Transmission. The street railway lasted until 1951, when it was no longer financially responsible to maintain. The author turned images of street cars that were used by Dominion Power and Transmission into trading cards that can be printed, cut out, shared, and traded, with the hope that they will spark excitement for public transportation! The cards can be used as a tool to learn about the history of public transportation in Hamilton, and invite investigation into its future.

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.
