Abstract

fetched live from OpenAlex

A new locomotive is about to be unveiled. Located on track 10, it is the first to be seen by the crowds as they pass through the south gate of Innotrans 2010. From the front, its shape is little different than its electric cousins currently laboring in Europe and North America. Walk around the massive corner post however, and you realize that things are not what they seem to be. At over 71 feet long and bristling with massive radiators and air grills, it becomes apparent that this locomotive is not your standard electric model. With the recognition of the pantograph and the diesel fuel ports, the intended purpose of this machine becomes clear. Looming over you is the new ALP-45 Dual Power (DP) Locomotive produced by Bombardier Transportation. Powered by the overhead catenary or by its twin diesel engines, the ALP-45DP will be the first of its kind in North America. Capable of producing 5360hp in electric mode, or 4200hp in diesel mode this locomotive will soon operate on the rail lines of NJ TRANSIT, as well as those of the Agence Metropolitaine de Transport (AMT) of Montreal. With a maximum weight of 72,000 lbs. per axle and a height no greater than 14’6”, the packaging of this locomotive has been a challenge. Three pilot locomotives have been recently completed and are about to begin testing. One locomotive will go to the Transportation Technology Center located in Pueblo, Colorado, while the other two will soon begin on-site testing at the authorities respective properties. This paper will explain the performance capabilities of the ALP-45DP as well as the technical challenges that were surmounted in order to bring this innovative locomotive to reality.

Full frame distilled prediction

Teacher imitation

Not 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.
