The EMD BL2 is a model of diesel-electric locomotive built by General Motors Electro-Motive Division (EMD). A total of 58 units were built between 1947 and 1949. The BL2 was not very successful, as it was unreliable and occupied a gap between carbody and hood units, which resulted in it suffering from the drawbacks of both designs. However, lessons learned from the BL2 were incorporated into EMD's next design, the GP7.
The EMD GP30 is a 2,250 hp (1,680 kW) four-axle diesel-electric locomotive built by General Motors Electro-Motive Division of La Grange, Illinois between July 1961 and November 1963. A total of 948 units were built for railroads in the United States and Canada, including 40 cabless B units for the Union Pacific Railroad.
Electro-Motive Corporation produced five 1800 hp B-B experimental passenger train-hauling diesel locomotives in 1935; two company-owned demonstrators, #511 and #512, the Baltimore and Ohio Railroad's #50, and two units for the Atchison, Topeka and Santa Fe Railway, Diesel Locomotive #1. The twin engine power unit layout and multiple unit control systems developed with the B-B locomotives were soon adopted for other locomotives such as the Burlington Route's Zephyr locomotives built by the Budd Company in 1936 and EMC's own EMD E-units introduced in 1937. The B-B locomotives worked as proof-of-concept demonstrators for diesel power with the service loads of full size trains, breaking out of its niche powering the smaller custom Streamliners.
The EMD FT is a 1,350-horsepower (1,010 kW) diesel-electric locomotive that was produced between March 1939 and November 1945, by General Motors' Electro-Motive Corporation (EMC), later known as GM Electro-Motive Division (EMD). The "F" stood for Fourteen Hundred (1400) horsepower and the "T" for Twin, as it came standard in a two-unit set. The design was developed from the TA model built for the C,RI&P in 1937, and was similar in cylinder count, axle count, length, and layout. All told 555 cab-equipped ”A” units were built, along with 541 cabless booster or ”B” units, for a grand total of 1,096 units. The locomotives were all sold to customers in the United States. It was the first model in EMD's very successful F-unit series of cab unit freight diesels and was the locomotive that convinced many U.S. railroads that the diesel-electric freight locomotive was the future. Many rail historians consider the FT one of the most important locomotive models of all time.
The EMD F3 is a 1,500-horsepower (1,100 kW) B-B freight- and passenger-hauling carbody diesel locomotive produced between July 1945 and February 1949 by General Motors’ Electro-Motive Division. Final assembly was at GM-EMD's La Grange, Illinois plant. A total of 1,111 cab-equipped lead A units and 696 cabless booster B units were built.
The EMD SD70 is a series of diesel-electric locomotives produced by the US company Electro-Motive Diesel in response to the GE Dash 9-44CW. Production commenced in late 1992 and since then over 5,700 units have been produced; most of these are the SD70M and SD70MAC models. While the majority of the production was ordered for use in North America, various models of the series have been used worldwide. All locomotives of this series are hood units with C-C trucks, except the SD70ACe-P4 and SD70MACH which have a B1-1B wheel configuration, and the SD70ACe-BB, which has a B-B-B-B wheel arrangement.
The EMD SD90MAC is a model of 6,000 hp (4,470 kW) 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, surpassed only by the dual-engined DDA40X.
The EMD DD35 was a 5,000 horsepower (3,700 kW) diesel-electric locomotive of D-D wheel arrangement built by General Motors Electro-Motive Division for the Union Pacific Railroad and Southern Pacific Railroad.
The EMD SD24 was a 2,400 hp (1,800 kW) six-axle (C-C) diesel-electric locomotive built by General Motors' Electro-Motive Division of La Grange, Illinois between July 1958 and March 1963. A total of 224 units were built for customers in the United States, comprising 179 regular, cab-equipped locomotives and 45 cabless B units. The latter were built solely for the Union Pacific Railroad.
The EMD SD60 is a 3,800 horsepower (2,800 kW), six-axle diesel-electric locomotive built by General Motors Electro-Motive Division, intended for heavy-duty drag freight or medium-speed freight service. It was introduced in 1984, and production ran until 1995.
Electro-Motive Diesel is a brand of diesel-electric locomotives, locomotive products and diesel engines for the rail industry. Formerly a division of General Motors, EMD is now owned by Progress Rail, a subsidiary of Caterpillar Inc. Electro-Motive Diesel traces its roots to the Electro-Motive Engineering Corporation, founded in 1922 and purchased by General Motors in 1930. After purchase by GM, the company was known as GM's Electro-Motive Division. In 2005, GM sold EMD to Greenbriar Equity Group and Berkshire Partners, and in 2010, EMD was sold to Progress Rail. Upon the 2005 sale, the company was renamed to Electro-Motive Diesel.
The EMD GP59 is a 4-axle diesel locomotive model built by General Motors Electro-Motive Division between 1985 and 1989. Power was provided by a 12-cylinder EMD 710G3A diesel engine, which could produce 3,000 horsepower (2,200 kW). This locomotive shared the same common frame with the EMD GP60, giving it an overall length of 59 feet 9 inches (18.21 m). It featured a 3,700-US-gallon fuel tank. 36 examples of this locomotive were built including three demonstrators. Norfolk Southern placed the only order for the GP59 and also acquired the three demonstrators which featured an aerodynamic cab.
The passenger locomotives derivatives of the General Motors EMD GP40 diesel-electric locomotive have been, and continue to be, used by multiple passenger railroads in North America. For passenger service, the locomotives required extra components for providing steam or head-end power (HEP) for heating, lighting and electricity in passenger cars. Most of these passenger locomotives were rebuilt from older freight locomotives, while some were built as brand new models.
The EMD GP22ECO is a 2,150 hp (1,600 kW) B-B diesel-electric locomotive rebuilt by Electro-Motive Diesel and Norfolk Southern's Juniata Shops. Initially EMD built two GP22ECO demonstrators, one based on a GP9 and one based on a GP40, but thus far all orders have been for conversions based on EMD GP40 and EMD GP40-2 series locomotives. The rebuild involves replacing the existing prime mover with an EPA Tier-II-compliant turbocharged V8 710G3A, with Electronic fuel injection. The prime mover is mated to an AR10 alternator for traction power, a CA6 alternator for control power, and a computerized control system. Applying this to a 6-axle locomotive results in a SD22ECO. Some 6-axle locomotives could alternately be converted into a SD32ECO, using a 3,150 hp (2,350 kW) V12 instead.
The South African Railways Class 34-600 of 1974 is a diesel-electric locomotive.
The South African Railways Class 34-800 of 1978 is a diesel-electric locomotive.
The South African Railways Class 37-000 of 1981 is a mainline diesel-electric locomotive.
The Spoornet Class 39-000 of 2006 is a South African diesel-electric locomotive from the Spoornet era.
The EMD 1010 or EMD 265 is a line of four-stroke diesel engines manufactured by Electro-Motive Diesel. The precursor to the 1010 was introduced around 1998 as the 265H or H-Engine. The H-engine was initially designed for use as a 6,300 hp (4,700 kW) 16 cylinder, the EMD SD90MAC; however, the early engines were found to be explosive, and unsuccessful in the market, with the proven EMD 710 2-stroke design being preferred. The EMD four-stroke engine was resurrected in 2015 to meet EPA Tier 4 emissions regulations.
