SD90MAC
The EMD SD90MAC is a model of C-C diesel-electric locomotive produced by General Motors Electro-Motive Division (EMD). It is, with the SD80MAC, one of the largest single-engined locomotives produced by EMD and among the most powerful diesel-electric locomotives, surpassed only by the dual-engined DDA40X. The SD9043MAC is the variant, using a 16-cylinder 710G engine instead of the H-engine, which was originally intended as a temporary alternative while EMD tried to solve the H-engine's issues. However, the accompanying upgrade program was never utilized by its customers. The SD90MAC's features include radial steering trucks with AC traction motors and an isolated safety cab which is mounted on shock absorbers to lessen vibrations in the cab. The SD90MAC, like the SD80MAC, SD70ACe, and SD70M-2, has a wide radiator section, nearly the entire width of the locomotive, which along with their size makes them easy to spot. As of 2019, some SD90MACs are still in service on ...

EMD SD70ACU
The EMD SD70 is a series of diesel-electric locomotives produced by the US company Electro-Motive Diesel. This locomotive family is an extension and improvement of the EMD SD60 series. Production commenced in late 1992 and since then over 5,700 units have been produced; most of these are the SD70M, SD70MAC, and SD70ACe models. While the majority of the production was ordered for use in North America, various models of the series have been used worldwide. All locomotives of this series are hood units with C-C trucks, except the SD70ACe-P4 and SD70MACH which have a B1-1B wheel configuration, and the SD70ACe-BB, which has a B+B-B+B wheel arrangement. Superseding the HT-C truck, a new bolsterless radial HTCR truck was fitted to all EMD SD70s built 1992–2002; in 2003 the non-radial HTSC truck (basically the HTCR made less costly by removing radial components) was made standard on the SD70ACe and SD70M-2 models; the radial HTCR truck remained available as an option.

EMD 265
The EMD 1010 or EMD 265 is a line of four-stroke diesel engines manufactured by Electro-Motive Diesel. The precursor to the 1010 was introduced around 1998 as the 265H or H-Engine. The H-engine was initially designed for use as a 16 cylinder, the EMD SD90MAC; however, the early engines were found to be unreliable, and unsuccessful in the market, with the proven EMD 710 2-stroke design being preferred. The EMD four-stroke engine was resurrected in 2015 to meet EPA Tier 4 emissions regulations. History H-Engine Development of the H-engine was announced in 1994 as a railway locomotive specific engine - the design was influenced by the transition to AC traction motors, which had increased adhesion and tractive effort characteristics, allowing an increase in usable power to be usefully converted traction - thus the new design was to have available for traction - a 6000 hp locomotive design would allow one to replace two of the very common 3000 hp SD40-2 locomotives. ...

Canadian Pacific Railway
The Canadian Pacific Railway () , also known simply as CPR or Canadian Pacific and formerly as CP Rail (1968–1996), is a Canadian Class I railway incorporated in 1881. The railway is owned by Canadian Pacific Kansas City, Canadian Pacific Kansas City Limited, known until 2023 as Canadian Pacific Railway Limited, which began operations as legal owner in a corporate restructuring in 2001. The railway is headquartered in Calgary, Alberta. In 2023, the railway owned approximately of track in seven provinces of Canada and into the United States, stretching from Montreal to Vancouver, and as far north as Edmonton. Its rail network also served Minneapolis–St. Paul, Milwaukee, Detroit, Chicago, and Albany, New York, in the United States. The railway was first built between eastern Canada and British Columbia between 1875 and 1885 (connecting with Ottawa Valley and Georgian Bay area lines built earlier), fulfilling a commitment extended to British Columbia when it entered Canadia ...

EMD SD80MAC
The EMD SD80MAC was a C-C diesel-electric locomotive. It was powered by a 20-cylinder version of EMD's 710G prime mover, and was the second diesel locomotive by GM-EMD to use a V20 engine, since EMD's SD45 series. 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 differences between the SD80MAC and SD90MAC include no external rear sandbox on the SD90MAC, no rear lighted number boards on the SD90MAC, and the placement of the front numberboards (above the cab windows on the SD80MAC, on the nose on most SD90MACs). The SD80MAC also had recessed red marker lights in the nose, an identifying feature unique to Conrail (CR) locomotives, although Norfolk Southern (NS) had removed the lights on most of their former Conrail engines. All 30 SD80MAC units built were delivered to Conr ...

EMD SD89MAC
The EMD SD89MAC was a AAR wheel arrangement#C-C, C-C diesel-electric locomotive produced by Electro-Motive Diesel, General Motors Electro-Motive Division. Along with the EMD SD80MAC, SD80MAC and EMD SD90MAC, SD90MAC, the SD89MAC was one of the largest single-engine locomotives produced by EMD. The SD89MAC featured radial steering trucks and an isolated cab (locomotive), cab which was mounted on shock absorbers to reduce vibration. The SD89MAC used AC traction motor technology. Like the SD90MAC, it was a hood unit fitted with a safety cab and has an enlarged radiator section, nearly the entire width of the locomotive, which makes it easy to spot. The frame of GM 92, the only SD89MAC ever built, has since been retrofitted with a different engine for Tier 4 compliance tests conducted by EMD. The SD89MAC was intended to be a less-powerful version of the EMD SD90MAC, SD90MAC, and eventual successor to the EMD SD70 series, SD70 series. One demonstrator was built, but generated no ...

Radial Steering Truck
A bogie ( ) (or truck in North American English) comprises two or more wheelsets (two wheels on an axle), in a frame, attached under a vehicle by a pivot. Bogies take various forms in various modes of transport. A bogie may remain normally attached (as on many railroad cars and semi-trailers) or be quickly detachable (as for a dolly in a road train or in railway bogie exchange). It may include suspension components within it (as most rail and trucking bogies do), or be solid and in turn be suspended (as are most bogies of tracked vehicles). It may be mounted on a swivel, as traditionally on a railway carriage or locomotive, additionally jointed and sprung (as in the landing gear of an airliner), or held in place by other means (centreless bogies). Although ''bogie'' is the preferred spelling and first-listed variant in various dictionaries, bogey and bogy are also used. Railway A ''bogie'' in the UK, or a ''railroad truck'', ''wheel truck'', or simply ''truck'' in No ...

EMD 710
The EMD 710 is a line of diesel engines built by Electro-Motive Diesel (previously General Motors' Electro-Motive Division). The 710 series replaced the earlier EMD 645 series when the 645F series proved to be unreliable in the early 1980s 50-series locomotives which featured a maximum engine speed of 950 rpm.40-series versions of the 645, save the initial teething problems with the 20-645E, which were eventually resolved, proved to be exceptionally reliable. The EMD 710 is a relatively large medium-speed two-stroke diesel engine that has displacement per cylinder, and a maximum engine speed of 900 rpm.Same parts suitable for 1000 rpm speed, yet rated lower because of earlier problems in EMD 645. Factory-fitted governor limits to 900 rpm. In 1951, E. W. Kettering (son of Charles F. Kettering) wrote a paper for the ASME entitled, ''History and Development of the 567 Series General Motors Locomotive Engine'', which goes into great detail about the technical obstacles that were e ...
