B&OCT 2 > B&O 199 > B&O 8422

Built as Baltimore & Ohio Chicago Terminal 2 in November, 1936. It was renumbered B&O 199 in August, 1942. It was rebuilt as an SWm at the B&O Glenwood Shops at Pittsburgh, Pennsylvania, in June, 1955, with a new EMD V12 567B prime mover. The hood was significantly raised and the new prime mover was placed on a new engine bed above the old Winton bed. It was renumbered B&O 8422 in the general renumbering of January-March, 1957, and traded in to EMD on December 1, 1970.

This locomotive is unique in that it is the only known Phase I SW, and lacks “falsies” at the step wells below the frame. This was added to every other EMD welded frame switcher until April, 1949. The steps on this unit bolt directly to the frame and are not welded in any way.

Closeup of Phase I B&OCT 2 step well. Note the bolted on step well and lack of welded on "falsies" as shown on all later Phase II step wells, exemplified by the following close up of a Rock Island unit.

Step well of Rock Island 505. Note the different shape of the step well curves near the truck, and the welded on falsie under the side frame. The front of the step well is smoothly welded and ground to a smooth finish, but B&OCT 2 was simply bolted on.

AT&SF SC 2151 step well. Note the heavy cast frame, which has been planed down on the side, and the different shape as the sideframe dips down to the step well. Note also the sharp angled step well toward the truck, with no hint of graceful curves.

B&O assigned this unit to DE-3 class when built, and reassigned class DS-2 in 1940. It was yet again reclassed as DS-2e in 1943.
