The All-American F7 defined railroading during the 1950s; nearly every notable Class 1 operated at least one and many rostered dozens, or even hundreds, of these locomotives. When one pictures Electro-Motive's classic streamlined diesels, the F7 most often comes to mind.
Almost all F-units were B-B locomotives, meaning that they ran on two Blomberg B two-axle trucks with all axles powered. The prime mover in F-units was a sixteen-cylinder EMD 567 series mechanically aspirated two-stroke diesel engine, progressing from model 16-567 through 16-567D.
The F7's prime mover is a 16-cylinder 567 B series diesel engine developing 1,500 hp (1.1 MW) at 800 rpm. The 567B is a mechanically aspirated two-stroke design in a 45-degree V engine configuration, with 567 cu in (9.29 L) displacement per cylinder, for a total of 9,072 cu in (148.66 L).
