EMD TR1
The EMD TR1 was a two-unit "cow-calf" diesel locomotive built by General Motors Electro-Motive Division of La Grange, Illinois, in 1941. Two pairs were built for the Illinois Central Railroad, the only purchaser. The locomotive units strongly resembled the EMD NW3, with a long frame, Blomberg B road trucks, and a large cab connected to a wide area of hood that tapered going forward. The locomotives incorporated the machinery of the EMD FT in switcher bodywork; a V16 EMD 567 diesel engine of in each unit. The cow and calf units were semipermanently coupled together with a drawbar instead of couplers, in similar fashion to the FT's twin-unit sets. The two locomotive pairs were numbered 9250A&B and 9251A&B, later renumbered 1350A&B and 1351A&B. They initially were assigned to Markham Yard south of Chicago, IL, but by the early 1950s had been reassigned to the yard at East St. Louis, IL. Both remained in this service until they were retired in 1966 and traded in to EMD in par ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Switcher
A switcher, shunter, yard pilot, switch engine, yard goat, or shifter is a small railroad locomotive used for manoeuvring railroad cars inside a rail yard in a process known as ''switching'' (US) or ''shunting'' (UK). Switchers are not intended for moving trains over long distances but rather for assembling trains in order for another locomotive to take over. They do this in classification yards (Great Britain: ''marshalling yards''). Switchers may also make short transfer runs and even be the only motive power on branch lines and switching and terminal railroads. The term can also be used to describe the workers operating these engines or engaged in directing shunting operations. Switching locomotives may be purpose-built engines, but may also be downgraded main-line engines, or simply main-line engines assigned to switching. Switchers can also be used on short excursion train rides. The typical switcher is optimised for its job, being relatively low-powered but with a hi ...

Bo′Bo′+Bo′Bo′ Locomotives
B-B and Bo-Bo are the Association of American Railroads (AAR) and British classifications of wheel arrangement for railway locomotives with four axles in two individual bogies. They are equivalent to the B′B′ and Bo′Bo′ classifications in the UIC system. The arrangement of two, two-axled, bogies is a common wheel arrangement for modern electric and diesel locomotives. Bo-Bo Bo-Bo is the UIC indication of a wheel arrangement for railway vehicles with four axles in two individual bogies, all driven by their own traction motors. It is a common wheel arrangement for modern electric and diesel-electric locomotives, as well as power cars in electric multiple units. Most early electric locomotives shared commonalities with the steam engines of their time. These features included side rods and frame mounted driving axles with leading and trailing axles. The long rigid wheelbase and the leading and trailing axles reduced cornering stability and increased weight. The Bo-Bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cow-calf Locomotives
In rail transport, a cow-calf (also cow and calf) locomotive is a set of switcher-type diesel locomotives. The set usually is a pair; some 3-unit sets (with two calves, also known as herds) were built, but this was rare. A cow is equipped with a driving cab; a calf is not. The two are coupled together (either with regular couplers or a semi-permanent drawbar) and are connected with MU cables and brake lines so that both locomotive units can be operated from the single cab. Cows are analogous to A units and calves to B unit road locomotives. Both have prime movers. Like the early EMD FT locomotives, the Cow-calf sets were typically built as mated pairs, with the Cow (or cabbed unit) and calf (or cabless unit) sharing a number. However this was not always the case, with over time many of the sets being broken up and couplers added to aid with versatility. Cow-calf locomotives can be distinguished from the sometimes very similar looking slug and slug mother sets by the fact that ...

Railway Locomotives Introduced In 1941
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer facil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Illinois Central Locomotives
Illinois ( ) is a state in the Midwestern United States. Its largest metropolitan areas include the Chicago metropolitan area, and the Metro East section, of Greater St. Louis. Other smaller metropolitan areas include, Peoria and Rockford, as well Springfield, its capital. Of the fifty U.S. states, Illinois has the fifth-largest gross domestic product (GDP), the sixth-largest population, and the 25th-largest land area. Illinois has a highly diverse economy, with the global city of Chicago in the northeast, major industrial and agricultural hubs in the north and center, and natural resources such as coal, timber, and petroleum in the south. Owing to its central location and favorable geography, the state is a major transportation hub: the Port of Chicago has access to the Atlantic Ocean through the Great Lakes and Saint Lawrence Seaway and to the Gulf of Mexico from the Mississippi River via the Illinois Waterway. Additionally, the Mississippi, Ohio, and Wabash rive ... [...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 model ...

EMD GP40
The GP40 is a 4-axle diesel-electric locomotive built by General Motors' Electro-Motive Division between November 1965 and December 1971. It has an EMD 645E3 16-cylinder engine generating . The GP40 is longer than its EMD 567D3A-engined predecessor, the GP35, and distinguished visually by its three 48-inch radiator fans at the rear of the long hood, while the GP35 has two large fans and a smaller one in between. It was built on a frame; the GP35 was built on a frame - as was the GP7, 9, 18, and 30. The difference in length can be seen in the GP40's ten handrail stanchions compared to the GP35's nine. 1,187 GP40s were built for 28 U.S. railroads; 16 were built for one Canadian carrier, Canadian National; and 18 were built for two Mexican carriers, Ferrocarril Chihuahua al Pacífico and Ferrocarriles Nacionales de México. 60 units were built with high-short-hoods and dual control stands for Norfolk & Western Railway. Two passenger versions, the GP40P and GP40TC, were a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
