The EMD F40PH is a four-axle 3,000–3,200 hp (2.2–2.4 MW) B-B diesel-electric locomotive built by General Motors Electro-Motive Division in several variants from 1975 to 1992. Intended for use on Amtrak's short-haul passenger routes, it became the backbone of Amtrak's diesel fleet after the failure of the EMD SDP40F. The F40PH also found widespread use on commuter railroads in the United States and with VIA Rail in Canada. Additional F40PH variants were manufactured by Morrison-Knudsen and MotivePower between 1988 and 1998, mostly rebuilt from older locomotives.
The GE U36B is a four-axle 3,600 hp (2.7 MW) B-B diesel-electric locomotive produced by General Electric from 1969 to 1974. It was primarily used by the Seaboard Coast Line Railroad and its successors, although thirteen provided the power for the original Auto Train. The U36B was the last GE high-horsepower universal series locomotive.
The EMD FL9 is a model of electro-diesel locomotive, capable of operating either as a traditional diesel-electric locomotive or as an electric locomotive powered from a third rail. Sixty units were built between October 1956 and November 1960 by General Motors Electro-Motive Division for the New York, New Haven and Hartford 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 line is the direct successor to the GE Dash 9 Series. 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.
A GE B39-8 is a 4-axle diesel-electric locomotive built by GE Transportation Systems. It is part of the GE Dash 8 Series of freight locomotives. Following the production of the first three units for the Atchison, Topeka and Santa Fe Railway, GE made many mechanical and electrical improvements that were reflected in a redesigned carbody for the remainder of production; these later units are sometimes unofficially referred to as B39-8E.
The GE Dash 8-32B is a 4-axle 3,150 hp (2,350 kW) diesel-electric locomotive built by GE Transportation between 1984 and 1989. It is part of the GE Dash 8 Series of freight locomotives.
The GE Dash 8-40B is a 4-axle diesel-electric locomotive built by GE Transportation between 1988 and 1989. It is part of the GE Dash 8 Series of freight locomotives.
The GE C39-8 is a 6-axle diesel-electric locomotive model built by GE Transportation Systems between 1984 and 1987. It is part of the GE Dash 8 Series of freight locomotives.
The GE Dash 9-40CW is a 4,000-horsepower (3,000 kW) diesel-electric locomotive built by GE Transportation Systems of Erie, Pennsylvania, between January 1996 and December 2004. 1,090 were built for Norfolk Southern Railway, as road numbers 8889 to 9978. 53 GE Dash 8-44CWs built to Dash 9 specifications were also built for CSX Transportation, carrying road numbers 9000 to 9052.
The Dash 8-40BW, or B40-8W, is a four-axle diesel locomotive built by GE Transportation for the Atchison, Topeka and Santa Fe Railway (ATSF) in the late 1980s and the early 1990s. It is part of the GE Dash 8 Series of freight locomotives.
The GE Dash 8-32BWH, also known as the P32-8BWH, B32-8WH, or P32-8, is a diesel-electric locomotive used by Amtrak in passenger train service, based on the GE Dash 8 Series of freight train locomotives. Built in 1991, they were the first locomotives purchased to replace the EMD F40PH. Amtrak originally used the Dash 8's on mainline trains but later used them largely for switching in yards, only being used on mainline trains when newer GE Genesis locomotives were unavailable. As of 2023, 16 of the original 20 remain in service with Amtrak, including two owned by Caltrans for use on Amtrak California services.
The GE C40-8W is a 6-axle diesel-electric locomotive built by GE Transportation Systems from 1989 to 1994. Often referred to as the Dash light series, it is part of the GE Dash 8 Series of freight locomotives. This locomotive model is distinguished from the predecessor Dash 8-40C by the addition of a newer "wide" or "safety" cab. A cowl-bodied version of this locomotive, built only for the Canadian market, was the GE Dash 8-40CM.
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 GE C44-8W is a 4,400 hp (3,280 kW) diesel-electric locomotive built by GE Transportation Systems of Erie, Pennsylvania, part of the GE Dash 8 Series of freight locomotives. They are considered to be pre-production Dash 9s with D9-44CW internals and software housed in a Dash 8 carbody. They were numbered CSX 9000-9052. The first three were originally supposed to be the last order of Dash 8s for CSX thus having the smaller Dash 8 carbody. They have been derated to 4000 horsepower and are now designated C40-9W.
The GE C40-8M is a 6-axle diesel locomotive built by GE Transportation Systems from 1990 to 1994. It is part of the GE Dash 8 Series of freight locomotives, and is often referred to as a Dash 8-40CM.
The GE three-power boxcabs were early electro-diesel hybrid switcher locomotives. These boxcabs were termed oil battery electrics to avoid the use of the German name Diesel, unpopular after World War I.
The Dash 9 Series is a line of diesel locomotives built by GE Transportation. It replaced the Dash 8 Series in the mid-1990s, and was superseded by the Evolution Series in the mid-2000s. Dash 9 series locomotives are some of the most common in the United States.
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 Dash 8 Series is a line of diesel-electric freight locomotives built by GE Transportation. It replaced the Dash 7 Series in the mid-1980s, and was superseded by the Dash 9 Series for freight usage and the Genesis Series for passenger usage in the mid-1990s.
