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.
The American Locomotive Company was an American manufacturer of locomotives, diesel generators, steel, and tanks that operated from 1901 to 1969.
A diesel locomotive is a type of railway locomotive in which the power source is a diesel engine. Several types of diesel locomotives have been developed, differing mainly in the means by which mechanical power is conveyed to the driving wheels. The most common are diesel-electric locomotives and diesel-hydraulic.
Brookville Equipment Corporation, based in Brookville, Pennsylvania, United States, manufactures railroad locomotives for industrial and light capacity switching needs. The company also builds and restores streetcars. The company used to be known as Brookville Locomotive Company.
An electro-diesel locomotive is a type of locomotive that can be powered either from an electricity supply or by using the onboard diesel engine. For the most part, these locomotives are built to serve regional, niche markets with a very specific purpose.
Railpower Technologies is a subsidiary of R.J. Corman Railroad Group that builds environmentally friendly hybrid Green Goat and Genset switching locomotives, founded by Frank Donnelly and Gerard Koldyk. Its locomotives have been purchased by Canadian Pacific Railway, BNSF Railway, Kansas City Southern Railway and Union Pacific Railroad among others.
National Railway Equipment Company is an American railroad equipment rebuilding, leasing, and manufacturing company, headquartered in Mt. Vernon, Illinois. NREC sells new and rebuilt locomotives to railroad companies worldwide, with an emphasis on the North American market.
The QJ was a type of heavy freight steam locomotive introduced in 1956 by the China Railway. The majority were built by Datong Locomotive Factory. The prototypes and early production of the class were designated HP, being redesignated as FD class during the Cultural Revolution, before becoming the QJ class in 1971.
The RP20CD is a diesel-electric road switcher locomotive built by Railpower Technologies. It is a "genset" locomotive, having three engine-generator sets.
The NRE 3GS21B is a low-emissions diesel genset locomotive built by National Railway Equipment (NRE). Instead of a single prime mover, the NRE genset locomotive is powered by three separate 700 horsepower (522 kW) Cummins QSK19C engines providing a total power output of 2,100 horsepower (1,570 kW). Each engine could be individually started or shut off depending on load reducing overall diesel emissions and improving fuel efficiency. More than 150 of the 3GS21B genset locomotives have been produced to date, with the majority of these units being manufactured at NRE's Mount Vernon shops in Southern Illinois. In addition, three road slug models have also been produced.
The NRE 1GS7B is a low-emissions diesel switcher locomotive built by National Railway Equipment. It is powered by a single Cummins QSK19C I6 engine which develops a total power output of 700 horsepower (522 kW). There have been nine 1GS7B locomotives produced to date, manufactured at NREC's Mount Vernon shops in Southern Illinois, and at NREC's Dixmoor shops. It's also the only current single-engine switcher marketed in NRE's N-ViroMotive catalog.
The Railpower GG20BGreen Goat is a low-emissions diesel hybrid switcher locomotive built by Railpower Technologies Corp. It is powered by a single Caterpillar C9 six cylinder inline engine developing 300 horsepower (224 kW), which is also connected to a large battery bank where both sources combine for a total power output of 2,000 horsepower (1,490 kW). To date, there have been more than 50 GG20B diesel-electric hybrid switchers manufactured since their first introduction in 2004.
The RP20BD is a diesel-electric switcher locomotive built by Railpower Technologies. It is a "genset" locomotive, having three engine-generator sets.
The NRE 3GS21C is a low-emissions diesel genset locomotive built by National Railway Equipment (NRE). It is powered by three Cummins QSK19C I6 engines with each one developing 700 horsepower (522 kW) and creating a total power output of 2,100 horsepower (1,570 kW). Instead of a single prime mover, the NRE genset locomotive has three engines that each can be turned off or on as power is needed reducing overall diesel emissions and improving fuel efficiency. At least 27 3GS21C genset locomotives have been produced to date at NRE's Mount Vernon shops in Southern Illinois.
The NRE 2GS14B is a low-emissions diesel switcher locomotive built by National Railway Equipment. It is powered by two Cummins QSK19C I6 engines with each one developing 700 horsepower (522 kW) and creating a total power output of 1,400 horsepower (1,040 kW). At least 7 2GS14B genset locomotives have been produced to date, with the majority of these units being manufactured at NREC's Mount Vernon shops in Southern Illinois.
The MPI MP21B is a low-emissions diesel switcher locomotive built by MotivePower. It is powered by three Cummins QSK19C I6 engines with each one developing 700 horsepower (522 kW) and creating a total power output of 2,100 horsepower (1,570 kW). One MP21B locomotive was manufactured, currently operated by Amtrak.
The NRE 2GS36C-DE is a low-emissions six-axle diesel-electric road switcher locomotive built by National Railway Equipment Company. It is part of NRE's N-ViroMotive line. It is powered by two Cummins QSK50L V16 engines rated at 1,800 horsepower (1,340 kW) each, for a total power output of 3,600 horsepower (2,680 kW). It has a starting tractive force of 126,000 pounds-force (560,000 N), an adhesion rate of 30%, and a minimum continuous speed of 13.9 miles per hour (22.4 km/h). It offers Tier III emissions compliance.
A genset locomotive is a locomotive in which a number of smaller diesel engines are used rather than a single large engine. The term is short for "generator set."
The MPI MP14B is a low-emissions diesel switcher locomotive built by MotivePower. It is powered by two Cummins QSK19C I6 engines with each one developing 700 horsepower (522 kW) and creating a total power output of 1,400 horsepower (1,040 kW).
The NRE 2GS12B is a low-emissions diesel genset switcher locomotive built by National Railway Equipment Company as part of its N-ViroMotive series of low-emission locomotives. It is powered by two Cummins QSK15, a straight-six engine, with each one developing 600 horsepower (450 kW) and creating a total power output of 1,200 hp (890 kW). The locomotives are compliant with the EPA's Tier 4 emissions standards requirements for non-road diesel engines.
