The F3 series improved on hauling power over the F2 and proved popular along both passenger and freight line routes for its time.

The EMD (Electro-Motive Division, General Motors) F3 was an immediate post-World War 2 diesel-fueled locomotive capable of serving both passenger and freight line service routes. Production totaled 1,807 units. The F3 succeeded the F2 (appearing 1946, 104 total units produced) and offered improved hauling capability. 1,807 in all were completed by EMD with manufacturing running from mid-1945 to early-1949.

The 1,807 total was comprised of 1,111 standard design forms, noted as "A units", and 696 cabless booster forms classified as "B units".

In the AAR notation, the wheel arrangement was B-B indicating a pair of (Blomberg B series) trucks with powered axles. Similar to the F2 before it, the newer design carried a sleek appearance with the driving cab set aft of a smoothly-contoured bow assembly with centered circular lights. Access to the cab was via hinged rectangular doors found along either side of the vehicle. The engine took up most of the length of the locomotive and was set behind the driving cab.

The locomotive measured 50.7 feet long with a beam of 10.7 feet and a height of 15 feet. Power was from an EMD 567B 2-stroke V16 diesel-fueled series prime mover outputting 1,500 horsepower. EMD also supplied its D-12 as the system generator. Four traction motors were in play (either EMD D-17-B or D27-B). All told, the locomotive could hit speeds of 103 miles-per-hour (166kmh). Tractive effort was 55,000lb.

The F3 was operated by a myriad of customers in the United States with Union Pacific Railroad leading the way at 89 A units (this alongside 90 B units as well). They were followed by Pennsylvania Railroad and Southern Pacific Railroad who each operated 80 A units (40 and 80 B units, respectively). Southern Railway has a fleet of 79 of the A type backed by 65 of the B type.
