EMD FP7
The EMD FP7 is a , B-B dual-service passenger and freight-hauling diesel locomotive produced between June 1949 and December 1953 by General Motors' Electro-Motive Division and General Motors Diesel. Final assembly was at GM-EMD's La Grange, Illinois plant, excepting locomotives destined for Canada, in which case final assembly was at GMD's plant in London, Ontario. The FP7 was essentially EMD's F7A locomotive extended by four feet to give greater water capacity for the steam generator for heating passenger trains. Design While EMD's E-units were successful passenger engines, their A1A-A1A wheel arrangement made them less useful in mountainous terrain. Several railroads had tried EMD's F3 in passenger service, but there was insufficient water capacity in an A-unit fitted with dynamic brakes. The Atchison, Topeka and Santa Fe Railway's solution was to replace the steam generators in A-units with a water tank, and so only fitted steam generators into the B-units. The N ...

Western Pacific 805-A
Western Pacific 805-A is a preserved EMD FP7 diesel-electric railroad locomotive built by the Electro-Motive Division of General Motors. It was mainly used to pull passenger trains, specifically the ''California Zephyr'' (CZ), which was operated jointly by the Western Pacific, Denver and Rio Grande Western, and the Chicago, Burlington and Quincy Railroads. It later worked for several short line railroads before preservation at the Western Pacific Railroad Museum at Portola, California. History WP 805-A was purchased to power Western Pacific Railroad's portion of the California Zephyr run less than one year after the train began on March 20, 1949. The 805-A was built in 1950 as part of an order by WP for 6 new passenger locomotives: 4 cab equipped A units numbered 804-A, 804-C, 805-A and 805-C, and 2 B units numbered 804-B and 805-B. These locomotives supplemented WP's existing fleet of F3 models, which were the original power for the CZ train. This cab unit, which wou ...

EMD F7
The EMD F7 is a model of diesel-electric locomotive produced between February 1949 and December 1953 by the Electro-Motive Division of General Motors (EMD) and General Motors Diesel (GMD). Although originally promoted by EMD as a freight-hauling unit, the F7 was also capable of passenger service, and used in hauling trains such as the Santa Fe Railway's high-speed flagship trains, the '' Super Chief, & El Capitan'', and the Ontario Northland's '' Northlander''. History The F7 was the fourth model in GM-EMD's successful line of F-unit locomotives, and by far the best-selling cab unit of all time. In fact, more F7s were built than all other F-units combined. The F7 succeeded the F3 model in GM-EMD's F-unit series, and was replaced in turn by the F9. Final assembly was at GM-EMD's La Grange, Illinois, plant or GMD's London, Ontario, facility. There was no F4, -5 or -6 model; "7" was chosen to match the contemporary twin-engine E7, and was also applied to the new GP ...

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 ...

EMD F-unit
EMD F-units are a line of diesel-electric locomotives produced between November 1939 and November 1960 by General Motors Electro-Motive Division and General Motors-Diesel Division. Final assembly for all F-units was at the GM-EMD plant at La Grange, Illinois, and the GMDD plant in London, Ontario. They were sold to railroads throughout the United States, Canada and Mexico, and a few were exported to Saudi Arabia. The term ''F-unit'' refers to the model numbers given to each successive type (i.e. F3, F7, etc.), all of which began with the letter ''F''. The ''F'' originally meant "fourteen", as in , not "freight". Longer EMD E-units for passenger service had twin diesel engines (called " prime movers" in that type of application). The ''E'' meant "eighteen" as in . Similarly, for early model EMD switchers, ''S'' meant "six hundred" and ''N'' meant "nine hundred horsepower" ( respectively). F-units were originally designed for freight service, although many without steam generat ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

EMD FP9
The EMD FP9 is an American , B-B dual-service passenger and freight-hauling diesel locomotive that was produced between February 1954 and December 1959 by General Motors Electro-Motive Division, and General Motors Diesel. Final assembly was at GM-EMD's La Grange, Illinois plant, except for Canadian orders, which were assembled by Canadian subsidiary GMD at London, Ontario. The FP9 was essentially EMD's F9 locomotive extended by to give greater steam generator and water capacity for hauling passenger trains. A total of 86 cab-equipped lead A units were built; unlike the freight series, no cabless booster B units were sold. Regular F9B units were sometimes used with FP9 A units, since they, lacking cabs, had more room for water and steam generators. The FP9 and its predecessor, the FP7, were offshoots of GM-EMD's highly successful F-unit series of cab unit diesel locomotives. Original owners EMD built 86 FP9 locomotives. The two largest buyers were the Canadian National Ra ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

B Unit
A B-unit, in railroad terminology, is a locomotive unit (generally a diesel locomotive) which does not have a control cab or crew compartment, and must therefore be operated in tandem with another 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 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 cannot be moved without a controlling unit attached, but most have some ... [...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 applie ...

Amtrak San Francisco Zephyr
The National Railroad Passenger Corporation, doing business as Amtrak (; ), is the national passenger railroad company of the United States. It operates intercity rail service in 46 of the 48 contiguous U.S. states and three Canadian provinces. ''Amtrak'' is a portmanteau of the words ''America'' and ''track.'' Founded in 1971 as a quasi-public corporation to operate many U.S. passenger rail routes, Amtrak receives a combination of state and federal subsidies but is managed as a for-profit organization. The company's headquarters is located one block west of Union Station in Washington, D.C. Amtrak is headed by a Board of Directors, two of whom are the secretary of transportation and chief executive officer (CEO) of Amtrak, while the other eight members are nominated to serve a term of five years. Amtrak's network includes over 500 stations along of track. It directly owns approximately of this track and operates an additional of track; the remaining mileage is over ra ...

Baggage Car
A passenger railroad car or passenger car (American English), also called a passenger carriage, passenger coach (British English and International Union of Railways), or passenger bogie (Indian English) is a railroad car that is designed to carry passengers, usually giving them space to sit on train seats. The term ''passenger car'' can also be associated with a sleeping car, a baggage car, a dining car, railway post office and prisoner transport cars. The first passenger cars were built in the early 1800s with the advent of the first railroads, and were small and little more than converted freight cars. Early passenger cars were constructed from wood; in the 1900s construction shifted to steel and later aluminum for improved strength. Passenger cars have increased greatly in size from their earliest versions, with modern bi-level passenger cars capable of carrying over 100 passengers. Amenities for passengers have also improved over time, with developments such as lighti ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Northern Pacific Railway
The Northern Pacific Railway was an important American transcontinental railroad that operated across the northern tier of the Western United States, from Minnesota to the Pacific Northwest between 1864 and 1970. It was approved and chartered by the 38th Congress of the United States in the national / federal capital of Washington, D.C., during the last years of the American Civil War (1861-1865), and received nearly of adjacent land grants, which it used to raise additional money in Europe (especially in President Henry Villard's home country of the new German Empire), for construction funding. Construction began in 1870 and the main line opened all the way from the Great Lakes to the Pacific Ocean, just south of the United States-Canada border when Ulysses S. Grant, drove in the final "golden spike" completing the line in western Montana Territory (future State of Montana in 1889), on September 8, 1883. The railroad had about of track and served a large area, including ... [...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.

Dynamic Brake
Dynamic braking is the use of an electric traction motor as a generator when slowing a vehicle such as an electric or diesel-electric locomotive. It is termed " rheostatic" if the generated electrical power is dissipated as heat in brake grid resistors, and " regenerative" if the power is returned to the supply line. Dynamic braking reduces wear on friction-based braking components, and regeneration lowers net energy consumption. Dynamic braking may also be used on railcars with multiple units, light rail vehicles, electric trams, trolleybuses, and electric and hybrid electric automobiles. Principle of operation Converting electrical energy to the mechanical energy of a rotating shaft (electric motor) is the inverse of converting the mechanical energy of a rotating shaft to electrical energy (electric generator). Both are accomplished through the interactions of armature windings with a (relatively) moving external magnetic field, with the armature connected to an electrical c ...
