With production restrictions lifted and the U.S. economy humming with pent-up demand, railroads clamored for new diesels to replace a steam fleet exhausted by wartime traffic. In July 1946, EMD introduced a new model F-unit, the F3. Horsepower was upgraded to 1500 and lessons learned on the FT gave the F3 better reliability and lower maintenance. Under the hood throbbed an improved 567-series V-12 engine. With 567 inches of displacement per cylinder, this same engine would power virtually the entire first generation of EMD diesel locomotives.
Model features include intricately detailed ABS body, metal chassis, 5-pole precision flywheel-equipped, skew-wound balanced motor, RP-25 metal wheels and metal axles, directional lighting and authentic paint scheme.
