Canadian National Railway (CN) Class E-7 steam locomotives were of 2-6-0 wheel arrangement in the Whyte notation, or 1′C in UIC classification. These locomotives were built for the Grand Trunk Railway (GT) from 1898 through 1908. Some of the class had been built as compound locomotives with 200 psi (1.4 MPa) boilers feeding 22.5-inch (570 mm) and 35-by-26-inch (890 mm × 660 mm) cylinders; but all save one had been rebuilt as simple single-expansion locomotives beginning in 1911. GT began adding superheaters to these locomotives in 1913. CN simplified the last compound and continued the superheating conversions, but some locomotives never received superheaters. Most of the class were scrapped in the 1930s; but number 713 worked on the Berlin Subdivision branch to Lewiston, Maine, until replaced by diesel locomotives in 1957, and was preserved in the Canadian Railway Museum.
