Long Hood Forward
The long hood of a hood unit-style diesel locomotive is, as the name implies, the longer of the two hoods (narrower sections of the locomotive body in front and behind of the cab) on a locomotive, particularly American-type freight locomotives. Equipment The long hood normally contains the diesel engine (prime mover), the main generator or alternator, the locomotive's cooling radiators, the dynamic brake resistor grids if fitted, and most of the locomotive's auxiliary equipment. Head-end power equipment, if fitted, is normally in the long hood; steam generators for heating older passenger cars may be either in the long or short hoods. Operating direction Normally, the long hood is the rear of the locomotive. For early hood unit models, this was not the case; railroads preferred to run with the long hood at the front and the cab at the rear (referred to as operating long hood forward or LHF). It is a common misconception that locomotives were run LHF to provide greater prote ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Norfolk () is a ceremonial and non-metropolitan county in East Anglia in England. It borders Lincolnshire to the north-west, Cambridgeshire to the west and south-west, and Suffolk to the south. Its northern and eastern boundaries are the North Sea, with The Wash to the north-west. The county town is the city of Norwich. With an area of and a population of 859,400, Norfolk is a largely rural county with a population density of 401 per square mile (155 per km2). Of the county's population, 40% live in four major built up areas: Norwich (213,000), Great Yarmouth (63,000), King's Lynn (46,000) and Thetford (25,000). The Broads is a network of rivers and lakes in the east of the county, extending south into Suffolk. The area is protected by the Broads Authority and has similar status to a national park. History The area that was to become Norfolk was settled in pre-Roman times, (there were Palaeolithic settlers as early as 950,000 years ago) with camps along the higher lan ...

Electro-Motive Diesel
Progress Rail Locomotives, doing business as Electro-Motive Diesel (EMD), is an American manufacturer of diesel-electric locomotives, locomotive products and diesel engines for the rail industry. The company is owned by Caterpillar through its subsidiary Progress Rail. Electro-Motive Diesel traces its roots to the Electro-Motive Engineering Corporation, a designer and marketer of gasoline-electric self-propelled rail cars founded in 1922 and later renamed Electro-Motive Company (EMC). In 1930, General Motors purchased Electro-Motive Company and the Winton Engine Co., and in 1941 it expanded EMC's realm to locomotive engine manufacturing as Electro-Motive Division (EMD). In 2005, GM sold EMD to Greenbriar Equity Group and Berkshire Partners, which formed Electro-Motive Diesel to facilitate the purchase. In 2010, Progress Rail completed the purchase of Electro-Motive Diesel from Greenbriar, Berkshire, and others. EMD's headquarters, engineering facilities and parts manufacturing ...

EMD SD40-2
The EMD SD40-2 is a C-C diesel-electric locomotive built by EMD from 1972 to 1989. The SD40-2 was introduced in January 1972 as part of EMD's '' Dash 2'' series, competing against the GE U30C and the ALCO Century 630. Although higher-horsepower locomotives were available, including EMD's own SD45-2, the reliability and versatility of the SD40-2 made it one of the best-selling models in EMD's history, edged only by the GP9, and the standard of the industry for several decades after its introduction. The SD40-2 was an improvement over the SD40, with modular electronic control systems similar to those of the experimental DDA40X. Peak production of the SD40-2 was in the mid-1970s. Sales of the SD40-2 began to diminish after 1981 due to the oil crisis, increased competition from GE's Dash-7 series and the introduction of the EMD SD50, which was available concurrently to late SD40-2 production. The last SD40-2 delivered to a United States railroad was built in July 1984, with pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EMD SD40
The EMD SD40 is an American 6-axle diesel-electric locomotive built by General Motors Electro-Motive Division between January 1966 and August 1972. 1,268 locomotives were built between 1966 and 1972. In 1972, an improved version with new electronics was developed and marketed as a new locomotive, the SD40-2. Design Like its predecessor in EMD's catalog, the SD35, the SD40 is a high-horsepower, six-axle freight locomotive. The SD40 is a member of EMD's long-running Special Duty class of locomotives, which all are built with 6 axles. In 1966, EMD updated its locomotive catalog with entirely new models, all powered by the new 645 diesel engine. These included six-axle models SD38, SD40, SDP40 and SD45. All shared standardized components, including the frame, cab, generator, trucks, traction motors, and air brakes. The primary difference was the power output: SD38 = from a non-turbocharged V16, SD40 = from a turbocharged V16, and SD45 = from a turbocharged V20. Original ...

EMD SD9
An SD9 is a 6-axle diesel locomotive built by General Motors Electro-Motive Division between January 1954 and June 1959. An EMD 567C 16-cylinder engine generated . Externally similar to its predecessor, the SD7, the SD9 was built with the improved and much more maintainable 567C engine. Four hundred and seventy-one SD9s were built for American railroads, while a further 44 were produced for export. Many SD9s both high and short-hood can still be found in service today on shortline railroads and industrial operators. Although most Class 1 roads stopped using these locomotives by the 1970s and 1980s, some remain in rebuilt form on some major Class I railroads, as switcher locomotives. History The SD9 was the second model of EMD's SD (special duty) line of locomotives, following the SD7. Just as the SD7 was a lengthened GP7 with two additional axles, the SD9 was a corresponding modification of the GP9. The additional axles in SD series locomotives provide more tractive effort a ...

It had an EMD 567B 16-cylinder engine producing for its six traction motors. 188 were built for United States railroads. This was the first model in EMD's SD ''(Special Duty)'' series of locomotives, a lengthened B-B GP7 with a C-C truck arrangement. The two extra axles and traction motors are useful in heavy, low speed freight service. EMD continues to produce SD series locomotives to this day. Many SD7s both high and short-hood can still be found in service today on shortline railroads and industrial operators, although most Class 1 roads stopped using these locomotives by the 1970s and 1980s. Some remain in rebuilt form on some major Class I railroads, as switcher locomotives.. Design and Production The SD7 was conceived as a modification of the existing EMD GP7 with two additional powered axles, one for each truck. Providing two more axles served t ...

EMD GP40X
An EMD GP40X is a 4-axle diesel-electric locomotive built by General Motors Electro-Motive Division between December 1977 and June 1978. Power for this unit was provided by a turbocharged 16-cylinder EMD 645F engine which could produce . 23 examples of this locomotive were built for North American railroads. This unit was a pre-production version meant to test technologies later incorporated into EMD's 50-series locomotives GP50 and SD50. Design Ten GP40X were delivered with an experimental HT-B truck design that became an option (but never used) on the production GP50, including 6 for Union Pacific and 4 for Southern Pacific. These trucks were meant to improve locomotive adhesion. The remainder rode on Blomberg-M trucks. SP's units included several experimental modifications, including L-shaped windshields and coverings over the radiator sections, nicknamed "elephant ears." 1965 experimental locomotive The designation GP40X was also given to an experimental locomotive bui ...

EMD GP38-2
The EMD GP38-2 is an American four-axle diesel-electric locomotive built by General Motors, Electro-Motive Division. Part of the EMD Dash 2 line, the GP38-2 was an upgraded version of the earlier GP38. Power is provided by an EMD 645E 16-cylinder engine, which generates 2,000 horsepower (1.5 MW). GP38-2W The GP38-2W is a Canadian variant of the GP38-2. It is easily distinguished by its wide-nose Canadian comfort cab. 51 of these locomotives were produced for the Canadian National Railway during 1973–1974. Although a W is commonly suffixed to the name, it is actually an addition by enthusiasts to help specify the presence of a CN-spec comfort cab. No locomotives built using CN's design of comfort cab ever featured a W in their designation, as the presence of the cab did not mechanically alter the locomotive. This is reflected by the lack of the "W" in the model designation on the builders' plates of these units. There are snow shields above the inertial-filter central a ...
