B-unit
A B-unit, in rail terminology, railroad terminology, is a locomotive unit (generally a diesel locomotive) which does not have a control cab (locomotive), cab or crew compartment, and must therefore be operated in tandem with another Railway coupling, coupled locomotive with a cab (an A-unit). The terms booster unit and cabless are also used. The concept is largely confined to North America and post-Soviet countries. Elsewhere, locomotives without driving cabs are rare. A B-unit is distinct from a Slug (railroad), slug unit, which only has traction motors and in certain instances may have a cab. The term primarily is applied to freight locomotives, but can be applied to passenger multiple units as well in some cases for when motor cars are put in the middle of trains. In practice however, the term is rarely used to describe multiple unit trains, and in many circumstances the non-cab cars are directly or indirectly permanently attached to a cab car. Controls Some B-units ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
A-unit
An A-unit, in railroad terminology, is a diesel locomotive (or more rarely an electric locomotive) equipped with a driving cab and a control system to control other locomotives in a multiple unit, and therefore able to be the lead unit in a consist of several locomotives controlled from a single position. This terminology is generally used in North America, since only there was it commonplace to build B-units—cabless locomotive units which normally could not lead a train. Typical features Typical driving cab features, and therefore A-unit features, include windshields, rectangular side windows, crew seats, heating, and sometimes, radios, air conditioning and toilets. B-units always lack all of these features, except that some EMD F-units have an extra porthole-style side window(s) for a hostler (an employee permitted to move a locomotive in a yard only, not on the road). Terminology This terminology has fallen out of use for newer locomotives, since it only really applied ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EMD FT
The EMD FT is a diesel-electric locomotive that was produced between March 1939 and November 1945, by General Motors' Electro-Motive Corporation (EMC), later known as GM Electro-Motive Division (EMD). The "F" stood for Fourteen Hundred (1400) horsepower (rounded from 1350) and the "T" for Twin, as it came standard in a two-unit set. The design was developed from the TA model built for the C,RI&P in 1937, and was similar in cylinder count, axle count, length, and layout. All told 555 cab-equipped ”A” units were built, along with 541 cabless booster or ”B” units, for a grand total of 1,096 units. The locomotives were all sold to customers in the United States. It was the first model in EMD's very successful F-unit series of cab unit freight diesels and was the locomotive that convinced many U.S. railroads that the diesel-electric freight locomotive was the future. Many rail historians consider the FT one of the most important locomotive models of all time. Design an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haysi Railroad
The Haysi Railroad Company (reporting mark HRR) was a terminal/switching railroad that owned and operated seven miles of track from Haysi, Virginia, to Vicey, Virginia. The railroad was known most for its unusual motive power. History The Haysi Railroad was founded in February 1970, after the Clinchfield railroad completed its Greenbrier Branch from Haysi-Vicey Virginia. HRR was controlled by the Seaboard Coast Line Railroad and Louisville and Nashville Railroad (later Family Lines System holding company in November 1972). It served coal mines in and around Haysi, Virginia. On June 1, 1983, the Seaboard System merged the Haysi Railroad, ending its existence as an independent entity. In 2007 the last of the coal operations on the line shut down, and since then the line has been unmaintained by CSX, virtually abandoned. Motive power The Haysi Railroad probably was best known for its unorthodox motive power, which included an EMD F7B that was built in February 1949 as Clin ...

Slug (railroad)
In railroading, a slug is a version of a diesel–electric locomotive which lacks a Prime mover (locomotive), prime mover and often a cab. It derives the electrical power needed to operate its traction motors and motor controls from a fully-powered mother locomotive. At low speeds the drawing (or regenerative braking, braking) force a diesel–electric locomotive can produce is often limited by its traction motors or the grip of its drive wheels on the track, not the capability of its diesel engine(s). A slug adds more traction motors and drive wheels to both use more of the power the mother's engine can produce that cannot otherwise be used at low speeds and provide better braking, without the expense of a full locomotive. A slug is distinct from a B unit, which has both a prime mover and traction motors but no cab. A slug may have an operator's cab to allow engineers to operate a train with the slug in the lead, or the cab and much of the body can be omitted to reduce cost an ...

EMD GP60B
The EMD GP60 is a model of 4-axle ( B-B) diesel-electric locomotive built by General Motors Electro-Motive Division between 1985 and 1994. The GP60 was EMD's first engine that was classified as a "third-generation" locomotive. Hidden behind the electrical cabinet doors on the rear wall of the cab, the GP60 concealed a trio of microprocessors that monitored and managed a host of engine, cooling system and control functions. The engine's on-board microprocessors replaced hundreds of wiring circuits, dozens of relays and all but one module card, making it an improvement among EMD's engines. Power was provided by a 16-cylinder 710G3A diesel engine, which could produce . This locomotive was 59 feet 9 inches long and featured a fuel tank. The GP60 series shared the same frame as the GP59. Cabless 'B' units of this locomotive model were also built; they were known as GP60B models. Units built with a North American Safety Cab were designated GP60M. These latter two types were ...

GE BQ23-7
The GE BQ23-7 was a model of diesel locomotive manufactured by General Electric, a variant of the B23-7 built between 1978 and 1979 (the 'Q' stood for "crew Quarters"). It was mechanically identical to a regular B23-7, but equipped with an enlarged operating cab for accommodating the train crew, thus making a case for eliminating the caboose from the rear of freight trains. SCL no.5130-5139 were the only ones built. Following a practice dating back to ACL and SAL U30Bs of 1967, SCL's 10 BQ23-7s and 30 standard B23-7s were delivered riding on reconditioned Blomberg trucks from EMD trade-ins. Only ten were built, all for the Seaboard Coast Line railroad, (originally no.5130–5139).

Chicago & North Western Railway
The Chicago and North Western was a Railroad classes#Class I, Class I railroad in the Midwestern United States. It was also known as the "North Western". The railroad operated more than of track at the turn of the 20th century, and over of track in seven states before retrenchment in the late 1970s. Until 1972, when the employees purchased the company, it was named the Chicago and North Western Railway (or Chicago and North Western Railway Company). The C&NW became one of the longest railroads in the United States as a result of mergers with other railroads, such as the Chicago Great Western Railway, Minneapolis and St. Louis Railway and others. By 1995, track sales and abandonment had reduced the total mileage to about 5,000. The majority of the abandoned and sold lines were lightly trafficked branches in Iowa, Illinois, Minnesota, South Dakota and Wisconsin. Large line sales, such as those that resulted in the Dakota, Minnesota and Eastern Railroad, further helped reduce th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BNSF GP60B 346
BNSF Railway is the largest freight railroad in the United States. One of six North American Class I railroads, BNSF has 36,000 employees, of track in 28 states, and over 8,000 locomotives. It has three Transcontinental railroad, transcontinental routes that provide rail connections between the western and eastern United States. BNSF trains traveled over in 2010, more than any other North American railroad. The BNSF Railway Company is the principal operating subsidiary of parent company Burlington Northern Santa Fe, LLC. Headquartered in Fort Worth, Texas, the railroad's parent company is a wholly owned subsidiary of Berkshire Hathaway Inc., of Omaha, Nebraska. The current CEO is Kathryn Farmer. According to corporate press releases, BNSF Railway is among the top transporters of intermodal freight in North America. It also hauls bulk cargo, including coal.

EMD E8
The EMD E8 is a , A1A-A1A passenger-train locomotive built by General Motors' Electro-Motive Division (EMD) of La Grange, Illinois. A total of 450 cab versions, or E8As, were built from January 1950 to January 1954, 447 for the U.S. and 3 for Canada. 46 E8Bs were built from December 1950 to January 1954, all for the U.S. The 2,250 hp came from two 12 cylinder model 567B engines, each driving a generator to power the two traction motors on one truck. The E8 was the ninth model in the line of passenger diesels of similar design known as EMD E-units. Starting in September 1953, a total of 21 E8As were built which used either the 567BC or 567C engines. In profile the front of the nose of E7, E8, and E9 units is less slanted than earlier EMD units, so E7/8/9s (and their four axle cousins, the F-unit series) have been nicknamed " bulldog nose" units. Earlier E-unit locomotives were nicknamed "slant nose" units. After passenger trains were canceled on the Erie Lackawanna ...

Burlington Northern
The Burlington Northern Railroad was a United States–based railroad company formed from a merger of four major U.S. railroads. Burlington Northern operated between 1970 and 1995. Its historical lineage begins in the earliest days of railroading with the chartering in 1848 of the Chicago and Aurora Railroad, a direct ancestor line of the Chicago, Burlington and Quincy Railroad, which lends Burlington, from Burlington, Iowa, to the names of various merger-produced successors. Burlington Northern acquired the Atchison, Topeka and Santa Fe Railway on December 31, 1996, to form the Burlington Northern and Santa Fe Railway (later renamed BNSF Railway), which was owned by the Burlington Northern Santa Fe Corporation. That corporation was purchased in 2009 by Berkshire Hathaway, which is controlled by investor Warren Buffett. History The Burlington Northern Railroad was the product of the merger of four major railroads: the Great Northern Railway (GN), the Northern Pacific Railwa ...

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 ...
