Long Hood
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). This is a holdover from the steam era of railroads where almost all locomotives were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

EMD GP7
The EMD GP7 is a four-axle (AAR wheel arrangement#B-B, B-B) diesel-electric locomotive built by General Motors Electro-Motive Division and General Motors Diesel between October 1949 and May 1954.Pinkepank, Jerry A. (1973) pp. 53 The GP7 was the first EMD road locomotive to use a hood unit design instead of a cab unit, car-body design. This proved to be more efficient than the car body design as the hood unit cost less to build, was cheaper and easier to maintain, and had much better front and rear visibility for switching. Power was provided by an EMD 567, EMD 567B 16-cylinder (engine), cylinder engine which generated . The GP7 was offered both with and B unit, without control cabs, and those built without control cabs were called a GP7B. Five GP7B's were built between March and April 1953. Of the 2,734 GP7's built, 2,620 were for American railroads (including 5 GP7B units built for the Atchison, Topeka and Santa Fe Railway), 112 were built for Canadian railroads, and 2 were ...

The EMD SD9 is a model of 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. 471 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 and more even ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 EMD GP38, 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 cen ...
