The EMD F9 is a 1,750 horsepower (1,300 kW)
By the time cab units such as the F9 were built, railroads were turning to the
Engine and powertrain
The F9 used a 16-cylinder 567C series Diesel engine developing 1,750 hp (1.30 MW) at 800 rpm. The 567 was designed specifically for locomotive applications, being a 45 degree V-type two-stroke design, with 567 cu in (9.29 L) displacement per cylinder, for a total of 9,072 cu in (148.66 L). A D.C. generator powered four D37 traction motors, two on each Blomberg B truck. EMD has built all of its major components since 1939. [1] [2]
Identification
An F9 can be distinguished reliably from a late F7 only by the addition of an extra filter grille ahead of the front porthole on the side panels on A units. Internally, the use of an 567C prime mover increased power to 1,750 hp (1.30 MW) from the F7's 1,500 hp (1.12 MW).
