Add an exact scale contoured and profiled fuel tank to your model. Can be used with walkway/frame modules (sold separately) or another existing locomotive product to upgrade non-scale components. Fuel tank is made from high quality, injection molded polystyrene and includes photo-etched end and top plates to give an exact rendering of the prototype. A contoured fit weight is also included. The top plate can be chosen to match specific fuel filler locations. If used with the walkway/frame modules, the fuel tank is properly aligned by a male/female connection and is slung a scale 1-1/2" from the bottom edge of the frame.
