These locomotives are decorated for the Baltimore & Ohio railroad in dark blue with a yellow stripe and lettering. A large, yellow "B & O" graces the sides of these locomotives. Each model comes fully assembled with wire handrails, etched metal grilles, cab interiors (on the FP7), and Kadee® couplers. The smooth drive is available either as DCC ready with the 8-pin NMRA compatible plug, or with the QSI sound system installed that will work on DC or DCC.
