EMD GP7
The EMD GP7 is a four-axle ( 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 Power was provided by an EMD 567B 16-cylinder engine which generated . The GP7 was offered both with and without control cabs, and those built without control cabs were called a GP7B. Five GP7B's were built between March and April 1953. The GP7 was the first EMD road locomotive to use a hood unit design instead of a 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. 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 built for Mexican railroads. This was the first model in EMD's GP ...

Baldwin Locomotive Works
The Baldwin Locomotive Works (BLW) was an American manufacturer of railroad locomotives from 1825 to 1951. Originally located in Philadelphia, it moved to nearby Eddystone, Pennsylvania, in the early 20th century. The company was for decades the world's largest producer of steam locomotives, but struggled to compete as demand switched to diesel locomotives. Baldwin produced the last of its 70,000-plus locomotives in 1951, before merging with the Lima-Hamilton Corporation on September 11, 1951, to form the Baldwin-Lima-Hamilton Corporation. The company has no relation to the E.M. Baldwin and Sons of New South Wales, Australia, a builder of small diesel locomotives for sugar cane railroads. History: 19th century Beginning The Baldwin Locomotive Works had a humble beginning. Matthias W. Baldwin, the founder, was a jeweler and whitesmith, who, in 1825, formed a partnership with machinist David H. Mason, and engaged in the manufacture of bookbinders' tools and cylinders for cal ...

Fairbanks-Morse
Fairbanks, Morse and Company was an American manufacturing company in the late 19th and early 20th century. Originally a weighing scale manufacturer, it later diversified into pumps, engines, windmills, coffee grinders, radios, farm tractors, feed mills, locomotives, and industrial supplies until it was purchased by Penn Texas 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 Fairbanks Morse and Company began in 1823 whe ...

ALCO
The American Locomotive Company (often shortened to ALCO, ALCo or Alco) was an American manufacturer of locomotives, diesel generators, steel, and tanks that operated from 1901 to 1969. The company was formed by the merger of seven smaller 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. The company changed its name to Alco Products, Incorporated in 1955. In 1964, the Worthington Corporation acquired the company. The company went out of business in 1969. The ALCO name is currently being used by Fairbanks Morse Engine for their FM, ALCO line. Foundation and early history The company was created in 1901 from the merger of seven smaller locomotive manufacturers with Schenectady Locomotive Engine Manufactory of Schenectady, New York: *Brooks Locomot ...

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 model ...

EMD GP9
The EMD GP9 is a four-axle diesel-electric locomotive built by General Motors' Electro-Motive Division between 1954 and 1959. The GP9 succeeded the GP7 as the second model of EMD's General Purpose (GP) line, incorporating a new sixteen-cylinder engine which generated . This locomotive type was offered both with and without control cabs; locomotives built without control cabs were called GP9B locomotives. EMD constructed 3,626 GP9s, including 165 GP9Bs. An additional 646 GP9s were built by General Motors Diesel, EMD's Canadian subsidiary, for a total of 4,257 GP9s produced when Canadian production ended in 1963. The GP9 was succeeded by the similar but slightly more powerful 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 567 engine, the 567C. Externally, the GP9 strongly resembled its predecessor. Most were built with high short ho ...

EMD SD7
An SD7 is a 6-axle diesel locomotive built by General Motors Electro-Motive Division between May 1951 and November 1953. 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 ...

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 larger railroads in the United States. The railroad was chartered in February 1859 to serve the cities of Atchison, Kansas, Atchison and Topeka, Kansas, and Santa Fe, New Mexico. The railroad reached the Kansas–Colorado border in 1873 and Pueblo, Colorado, in 1876. To create a demand for its services, the railroad set up real estate offices and sold farmland from the land grants that it was awarded by United States Congress, Congress. Despite being chartered to serve the city, the railroad chose to bypass Santa Fe, due to the engineering challenges of the mountainous terrain. Eventually Santa Fe Southern Railway, a branch line from Lamy, New Mexico, brought the Santa Fe railroad to its namesake city. 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 fleet of Santa Fe Railroad Tugboa ...

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. 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. Alco introduced the road switcher concept with the 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 hood was retained, though its increased length made visibi ...

Cylinder (engine)
In a reciprocating 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 to the energy generated from the combustion of the air/fuel mixture in the combustion chamber. In an ...
