| Two of the 1914 Baldwin Santa Fe's - 6009 (serial #41701) and 6030 - were converted to mighty ten-wheel switcher/pusher engines at the B&O company's shops in the mid-1920s. The modfications entailed much more than simply removing each truck. Indeed, the only dimensions that remained the same were the cylinder volume, driver diameter, and wheelbase. A new boiler shorter by 25% and pressed to a higher degree provided the steam from water heated in a smaller firebox. Axle loading increased, a useful change in heavy switcher. Specs - 58" drivers, 225 psi boiler pressure, 30x32" cylinders, engine weight of 349,500 lb, impressive tractive effort of 94,966 lb. This 8x10 photo might possibly be an original B&O builder's photo but not stamped with the B&O logo as most are. |
