Abstract
After the horrific and deadly train explosion at Lac-Mégantic, Que. in the summer of 2013, there are serious questions being raised publicly about the safety of Canada’s rail-transport system. Unfortunately, Canada’s public rail-safety data are currently in no shape to provide the answers to those questions. When Canadians ask, as many have in recent months, whether the rail-transport system is “safe,” they surely want to know whether the accident record is low — compared to other countries and to other forms of transport — and whether it has been improving or getting worse over time. Yet, the statistics that might provide the answers are worryingly inaccessible, sometimes conflicting, and in certain cases not available at all. The inability to publicly monitor airline safety statistics would be considered unacceptable. Yet trains transporting volatile goods across Canada arguably expose entire communities, as in Lac-Mégantic, to potentially catastrophic dangers. How is it, then, that the Transportation Safety Board, Transport Canada and Statistics Canada do not even publicly report something as basic as the number of train trips made every year in Canada? Nor do their statistics distinguish between incidents and accidents involving passenger trains and those involving freight trains. And how is it that the total number of accidents in some years is reported differently by these various monitoring organizations? If Canadians are, as it appears, destined to see increasing volumes of goods, specifically dangerous goods, transported by rail, it is that much more important that the federal government significantly improve the reporting of rail-safety data. It is not only vital that our railroads are safe; it is just as vital for the public to have information showing exactly how safe they are.

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; a candidate call from one teacher head, not a consensus.
