Data from Baldwin Locomotive Works Specification for Engines as digitized by the DeGolyer Library of Southern Methodist University, Volume 23, pp. 45 and 87. Works numbers were 17796 in May 1900, 17811 in June, and 18011 in August.
The ACR's trunk line runs Sault Sainte Marie almost due north to Hearst, Ontario. Having to abandon its dream of connecting Lake Superior with Hudson Bay (because it was there, at the very least ...), the ACR did reach Hearst in 1914. These Consolidations served the ACR until the mid-1920s.
In addition to the three shown here, which were delivered as simple-expansion engines, the fourth was built as a Vauclain compound; see Locobase 12422.
22 was sent to the scrapyard in May 1924, the other three were scrapped in 1926.

(Thanks to Wes Barris of steamlocomotive.com for his 28 June 2018 email reporting the missing metric equivalents to cylinder diameter and stroke.) Works number was 18033 in August 1900.
Identical to the three delivered with 21" x 30" cylinders (Locobase 14421), this engine was built as a Vauclain compound. As with all such compounds, a casting of one LP and HP cylinder, supplied through the single 12" (305 mm) piston valve, was placed on each side of the frame.
It was later converted to the simple-expansion configuration.
