The prime mover can also be a gas turbine instead of a diesel engine. In either case, the generator, traction motors and interconnecting apparatus are considered to be the power transmission system and not part of the prime mover. A wired-electric or battery-electric locomotive has no on-board prime mover, instead relying on an external power ...
The EMD E8 is a 2,250-horsepower (1,678 kW), A1A-A1A passenger-train locomotive built by General Motors' Electro-Motive Division (EMD) of La Grange, Illinois.A total of 450 cab versions, or E8As, were built from August 1949 to January 1954, 447 for the U.S. and 3 for Canada. 46 E8Bs were built from December 1949 to January 1954, all for the U.S.

The EMC E2 was an American passenger-train diesel locomotive which as a single unit developed 1,800 horsepower (1,300 kW), from two (2) 900 horsepower (670 kW) prime movers. These locomotives were typically operated as a unit set ( A - B - B ) or ( A - B - A ); where the three unit lashup developed 5400 horsepower.
The EMD F-units followed the basic B-B truck design of the TA model, but with a V-16 EMD 567 prime mover generating 1350 hp as introduced in 1939. E-units standardized the two engine configuration for passenger locomotives to maximize power and, while the less-reliable Winton Diesel prime movers were in use, faced a less severe loss of power ...
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. Structurally, the locomotive was a carbody unit , with the body as the main load-bearing structure, designed like a bridge truss and covered with cosmetic panels.
Upon the 2005 sale, the company was renamed to Electro-Motive Diesel. EMD's headquarters and engineering facilities are based in McCook, Illinois, [note 1] while its final locomotive assembly line is located in Muncie, Indiana. EMD also operates a traction motor maintenance, rebuild, and overhaul facility in San Luis Potosí, Mexico.
The EMD GP9 is a four-axle diesel-electric locomotive built by General Motors' Electro-Motive Division between 1954 and 1959. The GP9 succeeded the GP7 as the second model of EMD's General Purpose (GP) line, [1] incorporating a new sixteen-cylinder engine which generated 1,750 horsepower (1.30 MW). [2]
