Canadian Pacific 2-10-2 "Santa Fe" Type Locomotives

Class S2 (Locobase 4532)

Data from 1947 Canadian Pacific Locomotive Diagram book supplied in May 2005 by Allen Stanley from his extensive collection.

These Santa Fes were built by the railroad, as were many other designs. Although only this one version of the 2-10-2 wheel arrangement served on the CP, the class lasted until 1952-1954.
