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 ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GP10
The EMD GP10 is a diesel-electric locomotive that is the result of rebuilding a GP7, GP9 or GP18. The Illinois Central Railroad had three separate rebuild programs to upgrade their old EMD GPs and GPs that they had purchased from equipment dealers such as Precision National Corporation in Mount Vernon, Illinois. The first was the GP8, second the GP10 and third the GP11. All were rebuilt at IC/ICG's Paducah Shops in Kentucky. Core units for the GP10 program were from IC/ICG GP7, GP8, GP9 and GP18, B&M GP9, B&O GP9, CRR GP9, C&O GP7 and GP9, D&RGW GP9, DT&I GP7 and GP9, FEC GP9, GTW GP18, P&LE GP7, Potlach Forests Inc. GP7, QNS&L GP9, RDG GP7, St.J&LC GP9, SLSF GP7, SP GP9, SSW GP7, and UP GP9B. Two IC GP9s were rebuilt to GP10s and sold directly to the Ashley, Drew and Northern Railway. Nine Alaska Railroad GP7s were rebuilt to GP10s by Paducah, and renumbered 1801-1809 (these rebuilds received EMD angled cabs but kept their AAR Type B road trucks from Alco ...

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 ... [...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 models ...

Illinois Railway Museum
The Illinois Railway Museum (IRM, reporting mark IRMX) is the largest railroad museum in the United States. It is located in the Chicago metropolitan area at 7000 Olson Road in Union, Illinois, northwest of downtown Chicago. Overview History The museum was founded in 1953 by ten people who joined to purchase Indiana Railroad interurban car 65. Originally called the Illinois Electric Railway Museum, the museum was located on the grounds of the Chicago Hardware Foundry in North Chicago. In 1961, it was renamed to the Illinois Railway Museum to reflect its expanding scope. In 1964, the museum moved to Union, Illinois along the former right-of-way of the Elgin and Belvidere Electric Company. In 1968 the first steam locomotive was operated at the museum. The first storage barn was erected in 1972. In 1981, a streetcar loop was constructed. The right-of-way the museum was constructed next to still had back taxes into the 1980s. To gain full use of the track, the museum paid the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Illinois Terminal Railroad
The Illinois Terminal Railroad Company (reporting marks "ITC"), known as the Illinois Traction System until 1937, was a heavy duty interurban electric railroad with extensive passenger and freight business in central and southern Illinois from 1896 to 1956. When Depression era Illinois Traction was in financial distress and had to reorganize, the Illinois Terminal name was adopted to reflect the line's primary money making role as a freight interchange link to major steam railroads at its terminal ends, Peoria, Danville, and St. Louis. Interurban passenger service slowly was reduced, ending in 1956. Freight operation continued but was hobbled by tight street running in some towns requiring very sharp radius turns. In 1956, ITC was absorbed by a consortium of connecting railroads. History ITC was a successor in interest to a series of interurban railroads that were consolidated in the early 1900s by businessman William B. McKinley into the ''Illinois Traction System'' (ITS), an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Road Switcher
A road switcher is a type of railroad locomotive designed to both haul railcars in mainline service and shunt them in railroad yards. Both type and term are North American in origin, although similar types have been used elsewhere. A road switcher must be able to operate and have good visibility in both directions. As a road engine, a road switcher must be able to operate at road speeds, with suitable power and cooling capacity. It has high-speed road trucks rather than low-speed switcher only trucks. Modern road trucks are always equipped with "frictionless" roller bearings, whereas switcher trucks were almost always equipped with "friction" plain bearings, until plain bearings were outlawed in interchange service on both railcars and locomotives. Overview For the reasons given above, road switchers are generally hood units. The set-back cab of a hood unit provides more safety in the event of a collision at speed than most switcher designs, and the rear visibility is muc ...

General Motors Electro-Motive Division
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 ...

General Motors Diesel
General Motors Diesel was a railway diesel locomotive manufacturer located in London, Ontario, Canada. It was established in 1949 as the Canadian subsidiary of the Electro-Motive Diesel division of General Motors (EMD). In 1969 it was re-organized as the "Diesel Division of General Motors of Canada, Ltd." The plant was re-purposed to include manufacture of other diesel-powered General Motors vehicles such as buses. Following the Canada-United States Free Trade Agreement in 1989, all of EMD's locomotives were built at the London facility. In 2005 new owners of EMD renamed the Canadian subsidiary "Electro-Motive Canada". The plant was closed by EMD's new owner Progress Rail in 2012, with EMD's production remaining in LaGrange, Illinois and Muncie, Indiana. History Early diesel locomotive manufacturing in Canada Diesel-electric locomotives were built in Canada beginning in 1928. The earliest diesels were custom built one-of-a-kind designs such as Canadian Nationals numbers 9000 and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

AAR Wheel Arrangement
The AAR wheel arrangement system is a method of classifying locomotive (or unit) wheel arrangements that was developed by the Association of American Railroads. Essentially a simplification of the European UIC classification, it is widely used in North America to describe Diesel locomotive, diesel and electric locomotives (including third-rail electric locomotives). It is not used for steam locomotives, which use the Whyte notation instead. The AAR system counts axles instead of wheels. Letters refer to powered axles, and numbers to unpowered (or idler) axles. "A" refers to one powered axle, "B" to two powered axles in a row, "C" to three powered axles in a row, and "D" to four powered axles in a row. "1" refers to one idler axle, and "2" to two idler axles in a row. A dash ("–") separates Bogie, trucks or wheel assemblies. A plus sign ("+") refers to articulation, either by connecting bogies with span bolsters or by connecting individual locomotives via solid drawbars instead of ...
