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 ...

Fairbanks-Morse
Fairbanks, Morse and Company was an American manufacturing company in the late 19th and early 20th century. Founded in 1823 as a manufacturer of weighing scale, weighing scales, it later diversified into pumps, engines, windmills, coffee grinders, radios, farm tractors, feed mills, locomotives, and industrial supplies. It was purchased by the Penn-Texas conglomerate in 1958. There are three separate corporate entities that could be considered successors to the company, none of which is a complete and direct descendant of the original company. All claim the heritage of Fairbanks Morse and Company: * Fairbanks Scales is a privately owned company in Kansas City, Missouri, that manufactures scales * Fairbanks Morse Defense, a subsidiary company of Arcline Investment Management, is a company based in Beloit, Wisconsin, that manufactures and services engines * Fairbanks Nijhuis is a part of Pentair Water in Kansas City, Kansas, and manufactures pumps Founding and early history Fairb ...

ALCO
The American Locomotive Company (often shortened to ALCO, ALCo or Alco) was an American manufacturer that operated from 1901 to 1969, initially specializing in the production of locomotives but later diversifying and fabricating at various times diesel generators, automobiles, steel, tanks, munitions, oil-production equipment, as well as heat exchangers for nuclear power plants. The company was formed by the merger of seven locomotive manufacturers and Schenectady Locomotive Engine Manufactory of Schenectady, New York. A subsidiary, American Locomotive Automobile Company, designed and manufactured automobiles under the Alco brand from 1905 to 1913. ALCO also produced nuclear reactors from 1954 to 1962. After World War II, Alco closed all of its manufacturing plants except those in Schenectady and Montreal. In 1955, the company changed its name to Alco Products, Incorporated. In 1964, the Worthington Corporation acquired the company. The company went out of business in 1969, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of GM-EMD Locomotives
The following is a list of locomotives produced by the Electro-Motive Corporation (EMC), and its successors General Motors Electro-Motive Division (GM-EMD) and Electro-Motive Diesel (EMD). Streamlined power cars and early experimental locomotives EMC participated in the construction of a number of motorized railcars, integrated streamliner trainsets, and experimental locomotives in the 1930s. Most of these were short production runs (one, two, or four units) that were used by a single railroad. These consisted of Winton prime movers and General Electric generating, control, and transmission components inside a carbody whose assembly was subcontracted to another manufacturer, since EMC did not commence regular road locomotive production until 1937. Switchers (SW/NW/SC/NC/MP) The "S" designation originally stood for six hundred horsepower and the "N" designation for nine hundred horsepower, although they were used for the more general designation of smaller and larger engine mo ...

EMD GP9
The EMD GP9 is a four-axle diesel-electric locomotive built by Electro-Motive Diesel, General Motors' Electro-Motive Division between 1954 and 1963. The GP9 succeeded the EMD GP7, GP7 as the second model of EMD's General Purpose (GP) line, incorporating a new sixteen-cylinder (engine), cylinder engine which generated . This locomotive type was offered both with and without control cabs; locomotives built without control cabs were called GP9B locomotives. The GP9 was succeeded by the similar but slightly more powerful EMD GP18, GP18. Design and production EMD designed the GP9 as an improved version of the GP7, with an increase in power from 1,500 hp to 1,750 hp, and a change in prime mover to the latest version of the EMD 567, 567 engine, the 567C. Externally, the GP9 strongly resembled its predecessor. Most were built with high short hoods, but the Southern Pacific Transportation Company, Southern Pacific ordered a number with low short hoods for improved crew visibility. EMD b ...

EMD SD7
The EMD SD7 is a model of 6-axle diesel locomotive built by Electro-Motive Diesel, General Motors Electro-Motive Division between May 1951 and November 1953. It had an EMD 567B 16-cylinder (engine), cylinder engine producing for its six traction motors. United States railroads bought 188 units. This was the first model in EMD's SD ''(Special Duty)'' series of locomotives, a lengthened B-B EMD GP7, 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. Some SD7s both high and short-hood can still be found in service today on shortline railroads and industrial operators, although most Class I roads stopped using these locomotives by the 1970s and 1980s. Design and production The SD7 was conceived as a modification of the existing EMD GP7 with two additional powered axles, one for each Bogie, truck. Providing two more axles served two purposes: it gave the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atchison, Topeka And Santa Fe Railway
The Atchison, Topeka and Santa Fe Railway , often referred to as the Santa Fe or AT&SF, was one of the largest Class 1 railroads in the United States between 1859 and 1996. The Santa Fe was a pioneer in intermodal freight transport; at various times, it operated an airline, the short-lived Santa Fe Skyway, and the Santa Fe Railroad tugboats. Its bus line extended passenger transportation to areas not accessible by rail, and ferryboats on the San Francisco Bay allowed travelers to complete their westward journeys to the Pacific Ocean. The AT&SF was the subject of a popular song, Harry Warren and Johnny Mercer's " On the Atchison, Topeka and the Santa Fe", written for the film '' The Harvey Girls'' (1946). The railroad officially ceased independent operations on December 31, 1996, when it merged with the Burlington Northern Railroad to form the Burlington Northern and Santa Fe Railway. History Atchison, Topeka & Santa Fe Railway The railroad was chartered in February 1859 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cylinder (engine)
In an engine, the cylinder is the space in which a piston travels. The inner surface of the cylinder is formed from either a thin metallic liner (also called "sleeve") or a surface coating applied to the engine block. A piston is seated inside each cylinder by several metal piston rings, which also provide seals for compression and the lubricating oil. The piston rings do not actually touch the cylinder walls, instead they ride on a thin layer of lubricating oil. Steam engines The cylinder in a steam engine is made pressure-tight with end covers and a piston; a valve distributes the steam to the ends of the cylinder. Cylinders were cast in cast iron and later in steel. The cylinder casting can include other features such as valve ports and mounting feet. Internal combustion engines The cylinder is the space through which the piston travels, propelled by the energy generated from the combustion of the air/fuel mixture in the combustion chamber. In an air-cooled e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cab Unit
In North American railroad terminology, a cab unit is a railroad locomotive with its own cab and controls. "Carbody unit" is a related term, which may be either a cabless booster unit controlled from a linked cab unit, or a cab unit that contains its own controls. Characteristics With both body styles, a bridge-truss design framework is used to make the body a structural element of the locomotive. The body extends the full width and length of the locomotive. The service walkways are inside the body. Carbody units, gaining rigidity from the body trusswork, require less structural weight to achieve rigidity than do locomotives with non-structural bodies. For that reason, carbody construction was favored to increase the power-to-weight ratio for early diesel locomotives, before the power available with diesel technology was increased. Recent years have seen carbody construction revived in the quest for greater fuel efficiency with passenger locomotives. The full-width body ...

Hood Unit
A hood unit, in North American railroad terminology, is a body style for diesel and electric locomotives where the body is less than full-width for most of its length and walkways are on the outside. In contrast, a cab unit has a full-width carbody for the length of the locomotive and walkways inside. A hood unit has sufficient visibility to be operated in both directions from a single cab (locomotive), cab. Also, the locomotive frame is the main load-bearing member, allowing the hood to be non-structural and easily opened or even removed for maintenance. History The hood unit evolved from the switcher locomotive. A switcher's long hood is normally low enough that the crew can see over it, and there typically is no short hood. American Locomotive Company, Alco introduced the road switcher concept with the ALCO RS-1, RS-1, which was an enlarged switcher with a short hood ahead of the cab. This was added to provide protection for the crew in case of a collision. The low long ho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Locomotive
A locomotive is a rail transport, rail vehicle that provides the motive power for a train. Traditionally, locomotives pulled trains from the front. However, Push–pull train, push–pull operation has become common, and in the pursuit for longer and heavier freight trains, companies are increasingly using distributed power: single or multiple locomotives placed at the front and rear and at intermediate points throughout the train under the control of the leading locomotive. Etymology The word ''locomotive'' originates from the Latin language, Latin 'from a place', Ablative case, ablative of 'place', and the Medieval Latin 'causing motion', and is a shortened form of the term ''locomotive engine'', which was first used in 1814 to distinguish between self-propelled and stationary steam engines. Classifications Prior to locomotives, the motive force for railways had been generated by various lower-technology methods such as human power, horse power, Gravity railroad, g ...
