A locomotive or engine is a rail transport vehicle that provides the motive power for a train. If a locomotive is capable of carrying a payload, it is usually rather referred to as a multiple unit, motor coach, railcar or power car; the use of these self-propelled vehicles is increasingly common for passenger trains, but rare for freight trains.
An electric locomotive is a locomotive powered by electricity from overhead lines, a third rail or on-board energy storage such as a battery or a supercapacitor. Locomotives with on-board fuelled prime movers, such as diesel engines or gas turbines, are classed as diesel-electric or gas turbine-electric and not as electric locomotives, because the electric generator/motor combination serves only as a power transmission system.
GE Transportation is a division of Wabtec. It was known as GE Rail and owned by General Electric until sold to Wabtec on February 25, 2019. The organization manufactures equipment for the railroad, marine, mining, drilling and energy generation industries. The company was founded in 1907. It is headquartered in Pittsburgh, Pennsylvania, while its main manufacturing facility is located in Erie, Pennsylvania. Locomotives are assembled at the Erie plant, while engine manufacturing takes place in Grove City, Pennsylvania. In May 2011, the company announced plans to build a second locomotive factory in Fort Worth, Texas, which opened in January 2013.
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 succesor 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.
Prima is a family of railway diesel and electric locomotives built by Alstom. Manufacture of the type commenced in the late 1990s. By 2008, Alstom had reportedly sold 1,750 Prima locomotives. The second generation Prima II was launched in 2009. The Prima H3 diesel/battery hybrid locomotive was launched in 2013.
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 MPI MPXpress is a line of diesel-electric locomotives built by MotivePower for commuter rail service. There are five MPXpress models: MP36PH-3S, MP36PH-3C, MP40PH-3C, MP32PH-Q, and MP54AC.
A hybrid train is a locomotive, railcar or train that uses an onboard rechargeable energy storage system (RESS), placed between the power source and the traction transmission system connected to the wheels. Since most diesel locomotives are diesel-electric, they have all the components of a series hybrid transmission except the storage battery, making this a relatively simple prospect.
Westinghouse Air Brake Technologies Corporation, commonly known as Wabtec, is an American company formed by the merger of the Westinghouse Air Brake Company (WABCO) and MotivePower Industries Corporation in 1999. It is headquartered in Pittsburgh, Pennsylvania.
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 PowerHaul is a class of mainline diesel-electric locomotives designed by General Electric. Thirty locomotives were ordered by Freightliner in 2007; the first locomotive was completed in July 2009 at GE's Erie, Pennsylvania, plant.
The MPI MP33C is a model of diesel-electric freight locomotives designed and built by MotivePower in Boise, Idaho, USA. To date all orders have been for Australian operators.
The GE AC44C6M is an AC-traction 4,400-horsepower (3,300 kW) diesel locomotive, rebuilt from GE Transportation Dash 9 locomotives. AC44C6M rebuilds have been done by GE, American Motive Power, Inc., and Norfolk Southern Railway's Juniata and Roanoke Shops, starting in September 2015. The AC44C6M retains the 16-cylinder 7FDL-16 prime mover used in the core locomotive prior to rebuilding, but replaces the Dash 9's DC traction motors with alternating current GE 5GEB13B7 traction motors. Externally, the rebuilds have received new wide-nosed cabs, a new front hood section, and a new inverter cabinet behind the cab, while retaining the underframe and engine and radiator compartments of the original Dash 9 units.
MotivePower, Inc. (MPI) is an American manufacturer of diesel-electric locomotives. The company is a wholly-owned subsidiary of Wabtec, and traces its history back to the MK Rail division of Morrison-Knudsen.
The Diesel Locomotive Factory, Marhowrah is a joint venture of GE Transportation, part of American company Wabtec, with Indian Railways for the production of 1000 high-power freight locomotives over a period of 10 years designed to run on Indian railway tracks. This factory is located at Marhaura and started manufacturing the locomotives from September 2018.
The Indian locomotive class WDG-4G is a class of dual-cabin freight-hauling diesel-electric locomotive used by the Indian Railways (IR). The locomotive is designed by GE Transportation and is based on its Evolution Series, which are used in North America. The class is meant for freight hauling and replaces the older American Locomotive Company (ALCO)-designed locomotives, which have been the mainstay diesels of Indian Railways since 1962. Equipped with a 12-cylinder fully turbocharged GEVO engine, it is claimed to be 50% more environmentally friendly than its predecessors and is the first in the country to be compliant with level one of the emission norms set by the International Union of Railways (UIC-1). The locomotive has two cabs for easy reversal, both of which are air conditioned.
The Indian locomotive class WDG-6G is a class of diesel-electric locomotive used by the Indian Railways for freight duty. The locomotive is a higher power variant of the WDG-4G locomotive which was also designed by General Electric. The design platform is based on the GE Evolution Series and features a 4-stroke 16-cylinder fully turbocharged engine which delivers around 6,000 horsepower, making it the most powerful diesel locomotive of IR. It is the only 6,000 HP Diesel electric locomotive at 23t/axle weight, making it the lightest locomotive in its category in the world.
The Roy Hill railway, officially the Roy Hill Infrastructure railway, owned and operated by Hancock Prospecting, is a private rail network in the Pilbara region of Western Australia built to carry iron ore.
