The SD80MAC is a 5,000 horsepower (3.7 MW) C-C road switcher diesel-electric locomotive. The model uses a 20-cylinder version of EMD's 710G prime mover, and is the first diesel locomotive to use a 20-cylinder engine since EMD's SD45 and SD45-2. It introduced a wide radiator housing similar to GE Transportation locomotives and the placement of dynamic brakes at the rear of the locomotive, which is a quieter location, features that were incorporated into the SD90MAC and SD70ACe models. Key spotting difference between the SD80MAC and SD90MAC include no external rear sandbox on the SD90MAC, rear number boards, and the placement of the front numberboards. The SD80MAC also has recessed red marker lights in the nose, an identifying feature unique to Conrail locomotives, although Norfolk Southern (NS) has removed the lights on most of their former Conrail engines.
The EMD AEM-7 is a twin-cab four-axle 7,000 hp (5.2 MW) B-B electric locomotive built by Electro-Motive Division (EMD) and ASEA between 1978 and 1988. The locomotive is a derivative of the Swedish SJ Rc4 designed for passenger service in the United States. The primary customer was Amtrak, which bought 54 for use on the Northeast Corridor and Keystone Corridor. Two commuter operators, MARC and SEPTA, also purchased locomotives, for a total of 65.
As used in mechanical engineering, the term tractive force can either refer to the total traction a vehicle exerts on a surface, or the amount of the total traction that is parallel to the direction of motion.
General Electric Genesis is a series of passenger diesel locomotives produced by GE Transportation, then a subsidiary of General Electric. Between 1992 and 2001, a total of 321 units were built for Amtrak, Metro-North, and Via Rail.
The EMD F7 is a 1,500 horsepower (1,100 kW) Diesel-electric locomotive produced between February 1949 and December 1953 by the Electro-Motive Division of General Motors (EMD) and General Motors Diesel (GMD).
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. All locomotives of this series are hood units with C-C trucks, except the SD70ACe-P4 which has a B1-1B wheel configuration, and the SD70ACe-BB, which has a B-B-B-B wheel arrangement.
The EMD SD90MAC is a 6,000 hp (4,470 kW) C-C road switcher diesel-electric locomotive produced by General Motors Electro-Motive Division. It is, with the SD80MAC, one of the largest single-engined locomotives produced by EMD, surpassed only by the dual-engined DDA40X.
The British Rail Class 25 diesel locomotives, also known as Sulzer Type 2 were a class of 327 locomotives built between 1961 and 1967 for British Rail. They were numbered in two series, D5151-D5299 and D7500-D7677.
The GE C39-8 is a 6-axle road switcher 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.
NSB Di 4 is a class of five diesel-electric locomotives built by Henschel for the Norwegian State Railways (NSB). Delivered in 1981, the class is used to haul passenger trains on the Nordland Line and are since 2001 the only revenue diesel locomotives used by NSB. The locomotives had electric components from Brown, Boveri & Cie and a General Motors Electro-Motive Division 16-645E prime mover. This gives a power output of 2,450 kilowatts (3,290 hp) and a starting tractive effort of 360 kilonewtons (81,000 lbf).
The GE C40-8W is a 6-axle road switcher diesel-electric locomotive built by GE Transportation Systems from 1989 to 1994. Often referred to as a Dash 8-40CW, 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 New York Central Railroad's Niagara was a 4-8-4 "Northern" type steam locomotive named after the Niagara River and Falls. It had a 4-8-4 wheel arrangement and is considered as one of the most efficient 4-8-4 locomotives ever built.
The MK5000C is a 5,000 hp (3.7 MW) North American diesel-electric locomotive developed by MK Rail. At the time of its introduction in 1994, the MK5000C was the most powerful single prime mover diesel-electric locomotive ever made, a title it would hold for only for one year until GE Transportation released its competing 6,000 hp (4.5 MW) AC6000CW model in 1995.
The GE E60 is a family of six-axle 6,000 hp (4.5 MW) C-C electric locomotives made by GE Transportation Systems (GE) between 1972 and 1983. The E60s were produced in several variants for both freight and passenger use in the United States and Mexico. GE designed the locomotive for use on the Black Mesa and Lake Powell Railroad (BM&LP), a dedicated coal-hauling route in Arizona, which began operation in 1973. That same year GE adapted the design for high-speed passenger service on Amtrak's Northeast Corridor. The largest customer was Ferrocarriles Nacionales de México (NdeM), the state-owned railroad in Mexico, which bought 39 for a new electrification project in the early 1980s.
Class D16 on the Pennsylvania Railroad was their final development of the 4-4-0 "American" type of steam locomotive. A total of 429 of these locomotives were built at the PRR's Juniata Shops, spread across five subclasses; some had 80 in (2,030 mm) diameter driving wheels for service in level territory, while others had 68 in (1,730 mm) drivers for mountainous terrain. In the pre-1895 scheme, these locomotives were second class L.
Norfolk and Western 1218 is a preserved four-cylinder simple articulated 2-6-6-4 steam locomotive, built in June 1943 by the Norfolk and Western's (N&W) East End Shops in Roanoke, Virginia as part of the N&W's class "A" fleet of fast freight locomotives. It was retired from regular revenue service in 1959, and was later restored by Norfolk Southern for excursion service on their steam program, pulling excursions throughout the eastern United States from 1987 to 1991. Today, it was currently on static display at the Virginia Museum of Transportation in Roanoke, Virginia.
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 MPI MP20C is a switcher diesel locomotive designed and built by MotivePower in Boise, Idaho.
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.
The Great Northern H-5 was a class of 25 4-6-2 "Pacific" type steam locomotives that were originally built as E-14 4-6-0 "Ten Wheelers" by the Baldwin Locomotive Works in 1909 and operated by the Great Northern Railway until the mid 1950s.
