Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University Volume 28, p. 229 and Volume 29, p.99. Works numbers were 26350 in August 1905, 28464 in June 1906, 32216 in November 1907.
The Ferrocarril de Nacozari served copper mines in Sonora state by taking the ore to the big smelter at Moctezuma. At Nacozari de Garcia, the road connected to the branch of the El Paso & Southwestern that ran north to the border town of Douglas, Ariz.
Note: the suffix "de Garcia" is a honorific, saluting Jesus Garcia Corona, the engineer who saved the town from a dynamite explosion on 7 November 1907. Garcia ran the blazing 6-car train 6 kilometres from town before it exploded, demolished the train, and killed him and 12 rail workers.
