EMD F-units are a line of diesel-electric locomotives produced between November 1939 and November 1960 by General Motors Electro-Motive Division and General Motors-Diesel Division. Final assembly for all F-units was at the GM-EMD plant at La Grange, Illinois, and the GMDD plant in London, Ontario. They were sold to railroads throughout the United States, Canada and Mexico, and a few were exported to Saudi Arabia. The term F-unit refers to the model numbers given to each successive type, all of which began with the letter F. The F originally meant "fourteen", as in 1,400 horsepower (1,000 kW), not "freight". Longer EMD E-units for passenger service had twin 900-horsepower (670 kW) diesel engines. The E meant "eighteen" as in 1,800 horsepower (1,300 kW). Similarly, for early model EMD switchers, S meant "six hundred" and N meant "nine hundred horsepower".
The EMD Dash 2 is a line of diesel-electric locomotives introduced by General Motors' Electro-Motive Division (EMD) on January 1, 1972. Designations of these models were those of the former models with "-2" added. They retained the basic specifications of the earlier models in terms of power output and most other features, but introduced a number of improvements to the locomotives' internal systems, specifically the electrical systems and the trucks of the locomotives. These were intended to improve availability, efficiency, and ease of maintenance.
The EMD SD50 is a 3,500-horsepower (2,610 kW) diesel-electric locomotive built by General Motors Electro-Motive Division. It was introduced in May 1981 as part of EMD's "50 Series"; production ceased in January 1986. The SD50 was a transitional model between EMD's Dash 2 series which was produced throughout the 1970s and the microprocessor-equipped SD60 and SD70 locomotives. A total of 431 were built.
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 Evolution Series is a line of diesel locomotives built by GE Transportation Systems, initially designed to meet the U.S. EPA's Tier 2 locomotive emissions standards that took effect in 2005. The first pre-production units were built in 2003. Evolution Series locomotives are equipped with either AC or DC traction motors, depending on the customer's preference. All are powered by the GE GEVO engine.
The EMD 645 is a family of diesel engines that was designed and manufactured by the Electro-Motive Division of General Motors. While the 645 series was intended primarily for locomotive, marine and stationary engine use, one 16-cylinder version powered the 33-19 "Titan" prototype haul truck designed by GM's Terex division
The EMD GP38-2 is an American four-axle diesel-electric locomotive built by General Motors, Electro-Motive Division. Part of the EMD Dash 2 line, the GP38-2 was an upgraded version of the earlier GP38. Power is provided by an EMD 645E 16-cylinder engine, which generates 2,000 horsepower.
The EMD SD40 is an American 6-axle diesel-electric locomotive built by General Motors Electro-Motive Division between January 1966 and August 1972. 1,268 locomotives were built between 1966 and 1972. In 1972, an improved version with new electronics was developed and marketed as a new locomotive, the SD40-2.
The EMD 567 is a line of large medium-speed diesel engines built by General Motors' Electro-Motive Division. This engine, which succeeded Winton's 201A, was used in EMD's locomotives from 1938 until its replacement in 1966 by the EMD 645. It has a bore of 8+1⁄2 in (216 mm), a stroke of 10 in (254 mm) and a displacement of 567 cu in (9.29 L) per cylinder. Like the Winton 201A, the EMD 645 and the EMD 710, the EMD 567 is a two-stroke engine.
The EMD GL8 was an export diesel-electric locomotive introduced by General Motors Electro-Motive Division (EMD) in 1960. They have been designed as light locomotives with a low axle loading. Measuring 36 feet 2 inches over the end sills, they are equipped an EMD 8-567CR engine producing 875 hp (652 kW) for traction, driving four traction motors in either A1A-A1A or B-B flexicoil trucks. The EMD GA8 is a derivative designed for very light lines with extremely sharp curves using frame mounted traction motors and freight car trucks.
The EMD GT22CUM1 is a narrow gauge diesel-electric locomotive built by EMD. It has six axles in two trucks, giving it a C-C wheel arrangement. The name means a C-C locomotive, U for metre gauge, 12-cylinder 645 series. They were built for service in South America by the Villares with license of EMD. The Rede Ferroviaria Federal Sociedade Anonima (RFFSA) a state railroad in Brazil bought about 55 in the early 1980s in order to expand their locomotive roster. The RFFSA needed a powerful single-engined locomotive with light weight per axle for their metric system, and the GT22 represented the highest-rated model that EMD had to offer at the time.
The Stadler Euro is a class of diesel-electric locomotives built by Stadler Rail for the European market. It is available in two basic variants, the four-axle Euro 3000, and the six-axle Euro 4000. These locomotives are powered by EMD 710 prime movers. A six-axle electric-only variant is marketed as Euro 6000; it is also built for the Iberian gauge.
The GE Universal Series is a series of diesel locomotives intended for the export market introduced by General Electric in early 1956. General Electric had previously partnered with Alco, producing locomotives for export using Alco's 244 engine, and provided electrical parts for Alco's domestic production. However, with the advent of the Universal Series, GE ended its partnership with Alco and entered the export locomotive market on its own.
The EMD G22CU is a metre gauge diesel-electric locomotive designed and built by the Electro-Motive Division of General Motors. It was manufactured by several licensees, and exported to many countries including Argentina, Australia, Brazil, Egypt, Iran, New Zealand, Nigeria, Pakistan, South Korea, Yugoslavia and Taiwan (ROC).
The EMD G22 Locomotive Series made their debut in 1967 after the rise in popularity of the export EMD G12. Designed to meet most First World, Second World and Third World country requirements, the G22 Series was equipped with a naturally aspirated EMD 645 Series engine as well as four axle Flexicoil Type-B trucks which carried a low per-axle weight. Based on customer input, the G22 Series was defined by various designations that suited the customer's railway operations.
The EMD G22C Series were first introduced in 1968 to replace the popular G12 along with various improvements. They carried a low per axle weight on their Flexicoil Type-GC trucks and were the first model series to have a low nose as a standard option as well.
The EMD GT26 Locomotive Series made their debut in 1967 after the rise in popularity of the American EMD SD40. Designed to meet most First World, Second World and Third World countries, the GT26 Series were now equipped with a turbocharged high horsepower EMD 645 Series engine as well as six axle HT-C trucks to provide better traction effort at slow speeds. Based on customer input, the GT26 Series would be defined by various designations that suit the customer's railway operations.
The Dash 7 Series is a line of diesel-electric freight locomotives built by GE Transportation. It replaced the Universal Series in the mid-1970s, and was superseded by the Dash 8 Series in the mid-1980s.
The EMD G18 was an export locomotive introduced by GM-EMD in the late 1960s. The standard EMD suffixes applied after the G18 designation to indicate if the customer purchased locomotives with specific traction motors to fit narrow gauge (U) or broad gauge (W) rails. An (L) indicates a locomotive built with a lightweight frame, and (6) indicates A1A-A1A trucks. The similar EMD GA18 was a G18 designed as an extremely light locomotive with low axle loading and used freight car trucks driven by a cardan shaft and underframe mounted traction motors like its predecessor, the EMD GA8. A further variation was the G18B. They are powered by an EMD 8-645E prime mover rated at 1100 bhp and 1000 hp for traction and were produced with A1A-A1A or B-B trucks.
