Built by the American Locomotive Company in Schenectady, New York, this 4-4-0 Camelback or Mother Hubbard locomotive had its engineer's cab centered above the boiler because the wide firebox needed to burn hard northeastern anthracite coal left no room for a normal cab, while a separate shelter at the rear was provided for the fireman. It was built to haul passenger trains such as the Phoebe Snow and was exhibited at the New York World's Fair in 1939-40. It is 59 feet 2 inches long, has 69-inch driving wheels, 20 x 26-inch cylinders, boiler pressure of 185 pounds, and weighs 159,200 pounds in working order. It came to the museum in 1953 and was cosmetically restored in 1999-2002. The Lackawanna used the imaginary Phoebe Snow beginning in 1900 to promote its image as a clean railroad, showing an elegant woman stepping from a train in summer with her white linen dress still clean, and its advertising poems praised anthracite coal for keeping her dress white.
