When the 645 engine entered production in 1965, a large series of new locomotive models was introduced. The turbocharged version was used in EMD's 40 Series (GP40, SD40 and SD45) in 3,000 horsepower (2,200 kW), sixteen-cylinder form …

The following is a list of locomotives produced by the Electro-Motive Corporation (EMC), and its successors General Motors Electro-Motive Division (GM-EMD) and Electro-Motive Diesel (EMD). Streamlined power cars and early experimental locomotives

The 265H, at 6,300 hp (4,700 kW), was the most powerful engine ever produced by EMD and the first four-stroke engine offered to the market by EMD or its ancestral companies since the Winton 201A introduced their breakthrough in two-stroke diesel power in 1934.

Dec 16, 2024 · Some of the final models to carry it (the 567D3A) included the SD35 and GP30/GP35, all of which offered 2,500 horsepower and were the first second-generation designs EMD cataloged. The 645 engine was intended to further push horsepower output as trains were becoming larger and heavier.

Feb 14, 2022 · Electro-Motive’s first railroad motor car was propelled by a 175-horsepower gasoline engine; later EMC doodlebugs had various Winton engines producing between 225 and 400 hp. Here’s a comparison chart I created to illustrate how powerful each EMD model is as well as how many cylinders in each prime mover.

Maximum horsepower is required during, acceleration, for fast movement of trains, and for heavy pulling at economical speeds over ruling grades. Of these three basic requirements, the operation over ruling grades is probably the most important in practical railroading. The determination of the horsepower requirements of in­

The highly successful GP7 roadswitcher was introduced in 1949, with more than 2600 units eventually being produced. The GP7 used the 16-567B rated at 1500 HP engine while the successor GP9 used the 16-567C rated at 1750 HP. EMD photo from the "EMD Demonstrators and Displays" slide lecture program.

The turbocharged version was used in EMD's 40 Series (GP40, SD40 and SD45) in 3,000 horsepower (2,200 kW), sixteen-cylinder form and in 3,600 horsepower (2,700 kW), twenty-cylinder form. EMD also introduced the Roots-blown 38 Series (GP38, SD38) and turbocharged, twelve-cylinder 39 Series (GP39, SD39). All of these locomotive models extensively ...

Our two-cycle, medium-speed engines are available for marine, drilling, power generation and locomotive applications. The EMD ® 710 Series engine is available in 8-, 12-, 16-, and 20-cylinder configurations with continuous power ratings from 2,000 to 5,000 horsepower.

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.
