Abstract
Between 1990 and 2003, four new urban rail lines, totalling 723 miles, were inaugurated by MTA in Los Angeles (LA), California, USA. A fifth light rail line is under construction. Part of the existing freight railway network in the greater LA area was upgraded to commuter rail standards, becoming the Metrolink network. Metrolink was inspired by Go Transit in Toronto, CalTrain in San Francisco, TriRail in Miami and the 1996 Trinity Railway Express connecting Dallas with Fort Worth. Metrolink started in 1992 with a network of three lines radiating from Union Station. These are the Ventura County Line, the San Bernardino Line and the Santa Clarita Line. Most have been extended since 1992. Earthquakes in 1994 resulted in a growth in passengers and increased political support for commuter rail and increased subsidies, allowing new stations to be added and the Orange County Line to be upgraded to Metrolink standards. In 1995, Riverside Line was added and in 1996, the inland Empire-Orange County Line was added. In 2009, the Perris Valley Line will be added to the network. The present fleet comprises 38 locomotives and 143 double-deck carriages built by Bombardier. An order for 87 double-deck, push-pull coaches has been approved.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
