American Flyer Locomotive 3745 GP-7 Twin Unit Diesel

This is a complete history, pictures, descriptions, and information on the American Flyer Locomotive 374 375 GP-7 Twin Unit Diesel. The 374 375 was a GP7 Diesel Model.  The engine had a worm drive motor and built-in air horn.  The Locomotive 3745 was made from 1953 to 1955. American Flyer had three basic types of diesel trucks.  Diesel naming convention moved away from the steam Whyte system and focused on Axels instead of wheels.  GP7 trucks with two powered axles, PA/PB trucks with simulated three powered axles (also used on the EP-5 Electric style locomotive) and the Baldwin diesel trucks had two powered axles. The F9 may have simply used the Baldwin trucks.  This would make the GP7 locomotives B-B type, the PA/PB and electric locomotives C-C type and the Baldwins, B-B type also. F9’s probably B-B as well.
