Mogul (2-6-0) No. 1870 of the Wabash Railroad poses for an anonymous photographer at an unknown location, probably in southern Ontario. This engine was a member of class F-7, built by ALCo's Richmond Works and the Baldwin Locomotive Works between 1901 and 1904. No. 1807's Stephenson valve gear and squared slide valve chamber are earmarks of locomotives of her era, and the entire class was retired between 1931 and 1947. These engines had 64-inch drivers and 19x28-inch cylinders, and carried 200 p.s.i. of boiler pressure. They produced 26,849 pounds of tractive effort. Tom Rock of Rock on Trains supplied this image.
