This GP7 or GP9 on display at the B&O Museum in
Baltimore, MD wears the Chessie System scheme which
united the three combined roads C&O, B&O, and WM.
The short hood of this unit does not wear the Chessie
Cat logo which indicates this is the rear and is
consistent with early B&O operation. Units transfered
from the C&O wore the logo on the short hood.
