Canadian National class S 2-8-2

Add article description

Canadian National Railway (CN) Class S locomotives were a Class of 2-8-2 wheel arrangement in the Whyte notation, or 1′D1′ in UIC classification. These locomotives were designed for 16° operating curvature. The first examples of this very successful class were built for the Grand Trunk Railway in 1913. Major purchases of the class continued through 1924. Sub-classes S-3 and S-4 employed higher pressure boilers with smaller diameter cylinders to achieve similar tractive effort with higher efficiency. The class remained in freight service until the final replacement of steam with diesel-electric locomotives. 53 were renumbered between 4045 and 4097 in 1956.^[1]
