Abstract
On-street running in mixed traffic has been identified as the least desirable right-of-way for light rail and tram systems. While most cities in the developed world have withdrawn streetcar systems, substantial networks have been retained in Melbourne, Australia, and Toronto, Canada. Although some commentators have seen the retention of these systems as visionary, there are substantial challenges to be faced in addressing conflicts between streetcars and rising road traffic. Poor running speeds, unreliability, safety, and difficulties in providing universal access are significant issues for modern streetcar systems. Experiences are described in regard to planning and operating the Melbourne and Toronto streetcar systems. The types of challenges being faced in providing services are contrasted. Programs to address the challenge of creating modern high-quality transit systems out of streetcars are compared. Finally, success strategies in modernizing streetcar systems are identified.

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
