The Baltimore & Ohio never bought a modern class of 0-8-0s, but converted a large number of class E-24 and E-27 Consolidations into 0-8-0 switchers by removing the lead truck and installing a footboard pilot. This locomotive came from American Locomotive Company's Richmond works in 1903 as 2-8-0 No. 2271 of class E-24. The B&O converted it into 0-8-0 No. 1073 in 1928 and assigned it to class L-1a; in 1954 it was renumbered to 1518, and assumed its final number 817 in the B&O's late-steam renumbering. Here the engine poses at Cleveland in September 1956 in an image contributed by Edward Lorence from his collection; the photographer is not specified. These switchers had 57-inch drivers, 25x28-inch cylinders, and a boiler pressure of 210 p.s.i. They weighed 210,000 pounds and exerted 54,800 pounds of tractive effort.
