  2. EMD SD80MAC - Wikipedia

    en.wikipedia.org/wiki/EMD_SD80MAC

    It was powered by a 20-cylinder version of EMD's 710G prime mover, and was the second diesel locomotive by GM-EMD to use a V20 engine, since EMD's SD45 series. It introduced a wide radiator housing similar to GE Transportation locomotives and the placement of dynamic brakes at the rear of the locomotive, which is a quieter location, features ...

  3. EMD E-unit - Wikipedia

    en.wikipedia.org/wiki/EMD_E-unit

    The 201-A engines used in E-units were 900 hp (700 kW) V12s. Experience with the 201-A, which was the first two-stroke Diesel engine in operational use, was invaluable in the development of the next-generation Diesel engine, the EMD 567, a purpose-designed engine that achieved a factor-of-five improvement in piston life for locomotive use.

  4. List of EMD locomotives - Wikipedia

    en.wikipedia.org/wiki/List_of_EMD_locomotives

    The "S" designation originally stood for six hundred horsepower and the "N" designation for nine hundred horsepower, although they were used for the more general designation of smaller and larger engine models after the more powerful 567 model engines replaced the Winton engines. The "C" designation stood for cast frame locomotives and the "W ...

  5. EMD SD90MAC - Wikipedia

    en.wikipedia.org/wiki/EMD_SD90MAC

    The EMD SD90MAC is a model of 6,000 hp (4,470 kW) [1] C-C diesel-electric locomotive produced by General Motors Electro-Motive Division (EMD). It is, with the SD80MAC, one of the largest single-engined locomotives produced by EMD and among the most powerful diesel-electric locomotives, surpassed only by the dual-engined DDA40X.

  6. EMC E2 - Wikipedia

    en.wikipedia.org/wiki/EMC_E2

    A single engine crew in the cab, remotely monitored and controlled all three motive power units from a single control station in the cab. The locomotives were diesel-electrics with two 900 hp Winton 201-A engines each, with each engine driving its own generator to power the traction motors. In addition the locomotives contained steam generators ...

  7. EMD SD50 - Wikipedia

    en.wikipedia.org/wiki/EMD_SD50

    The SD50 was produced in response to increasingly tough competition from GE Transportation, whose Dash 7 line was proving quite successful with railroads. While EMD's SD40-2 was a reliable and trusted product, GE's line included locomotives up to 3,600 hp (2,685 kW) with more modern technology, as well as very competitive finance and maintenance deals.

  8. EMC E3 - Wikipedia

    en.wikipedia.org/wiki/EMC_E3

    The 2,000 hp (1,500 kW) was achieved by putting two 1,000 horsepower (750 kW), 12-cylinder, model 567 engines in the engine compartment. Each engine drove its own electrical generator to power the traction motors. The E3 was the fourth model in a long line of passenger diesels of similar design known as EMD E-units.

  9. EMD GP15 - Wikipedia

    en.wikipedia.org/wiki/EMD_GP15

    It was a very close cousin to the GP15-1, but used a turbocharger in order to generate more power from a smaller engine. Power was provided by an 8-cylinder diesel engine that generated 1,500 hp (1.12 MW), the same as the GP15-1, but with four fewer cylinders. [1] 28 examples of this locomotive model were built for American railroads.
