American Model Toys - AMT F-7 Diesel Locomotives
These locomotives use a powerful 7-pole AC/DC Pittman motor, which is rated for operation up to 25 volts. Neoprene Traction Tread rubber tires are installed on all four drive wheels, thus making these locomotives excellent pullers. A matching B unit was designed, but never produced. Due to the injection molding process that AMT used, the locomotive roofs are humped in the center. The later Kusan F-7s had straight roof lines.
