Canadian Pacific 2-10-2 Locomotives in Canada
Class Details by Steve Llanso of Sweat House Media
Class S2 (Locobase 4532)
Data from 1947 Canadian Pacific Locomotive Diagram book supplied in May 2005 by Allen Stanley from his extensive Rail Data Exchange. See also [
] on these Santa Fes. (Thanks to Chris Hohl for his 2 April 2013 email pointing me to this article and for noting the tender variations.)
These Santa Fes were built by the railroad, as were many other designs. Most of their service was spent pushing from the rear or helping from the front. As a result their tenders were either the 8,000 gallon/14 ton version shown in the specs or a smaller one holding 6,000 Imperial gallons (22,710 litres) of water and 12 tons of coal.
Although only this one version of the 2-10-2 wheel arrangement served on the CP, the class lasted until 1952-1954.
