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
Built by the Budd Company, but designed by EMD [1] 532 Baltimore and Ohio #50 August 1935 1,800 hp B-B Baltimore and Ohio Railroad (B&O) Chicago and Alton Railroad (C&A) Gulf, Mobile and Ohio Railroad (GM&O) 1937 (B&O) Stored at the National Museum of Transportation in St. Louis, Missouri: Built by General Electric (GE), but designed by EMD [2] [3]
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 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 rebuild included an EMD 645 prime mover, producing 3,000 hp (2,200 kW), and a separate head-end power (HEP) generator. [ 13 ] Between 2017 and 2018, the GP40-2H locomotives received an overhaul performed by National Railway Equipment and were reclassified as GP40-3H.
The Southern Pacific Transportation Company had rebuilt a total of 167 EMD SD45 units into EMD SD45R diesel locomotives at their own Sacramento Shops under the Southern Pacific's M-99 rebuild program and renumbered their units as 7400 through 7566. Most of them in their SD45 form were classified by the Southern Pacific as EF636-1, EF636-2 ...
The added "headroom" in power extended the life of mechanical parts, which was a critical issue with early diesel engines in locomotives. The units were built with AAR type B two-axle trucks. As development design locomotives, modifications were frequently made to them to overcome various teething problems; the EMC demonstrators spent ...
