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 ...

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. History Atchison, Topeka & Santa Fe Railway The railroad was chartered in February 1859 to se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tractive Effort
In railway engineering, the term tractive effort describes the pulling or pushing capability of a locomotive. The published tractive force value for any vehicle may be theoretical—that is, calculated from known or implied mechanical properties—or obtained via testing under controlled conditions. The discussion herein covers the term's usage in mechanical applications in which the final stage of the power transmission system is one or more wheels in frictional contact with a railroad track. Defining tractive effort The term ''tractive effort'' is often qualified as ''starting tractive effort'', ''continuous tractive effort'' and ''maximum tractive effort''. These terms apply to different operating conditions, but are related by common mechanical factors: input torque to the driving wheels, the wheel diameter, coefficient of friction () between the driving wheels and supporting surface, and the weight applied to the driving wheels (). The product of and is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

EMD E7
The E7 was a , A1A-A1A passenger train locomotive built by General Motors' Electro-Motive Division of La Grange, Illinois. 428 cab versions, or E7As, were built from February 1945 to April 1949; 82 booster E7Bs were built from March 1945 to July 1948. (Circa 1953 one more E7A was built by the Los Angeles General Shops of the Southern Pacific by rebuilding an E2A.) The 2,000 hp came from two 12 cylinder model 567A engines. Each engine drove its own electrical generator to power the two traction motors on one truck. The E7 was the eighth model in a line of passenger diesels of similar design known as EMD E-units, and it became the best selling E model upon its introduction. In profile the front of the nose of an E7A was less slanted than on earlier EMD passenger locomotives, and the E7, E8, and E9 units have been nicknamed “ bulldog nose” units. Some earlier units were called “shovel nose” units or “slant nose” units. In film A Gulf, Mobile and Ohio R ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

La Grange, Illinois
La Grange ( ; often spelled LaGrange) is a village (United States)#Illinois, village in Cook County, Illinois, United States. It is a suburb of Chicago. The population was 16,321 at the 2020 census. History The area around La Grange was first settled in the 1830s, when Chicago residents moved out to the west due to the rapid population increase in the city in the decade since its incorporation. The first settler, Robert Leitch, came to the area in 1830, seven years before the City of Chicago was incorporated. La Grange's location, at approximately from the Chicago Loop, is not considered far from the city by today's standards, but in that time the residents enjoyed the peace of rural life without much communication with urban residents. The village was officially incorporated on June 11, 1879. It was founded by Franklin Dwight Cossitt, who was born in Granby, Connecticut, and raised in Tennessee, and moved to Chicago in 1862 where he built a successful wholesale grocery busines ...

EMD F9
The EMD F9 is a Diesel-electric locomotive produced between February 1953 and May 1960 by the Electro-Motive Division of General Motors (EMD) and General Motors Diesel (GMD). It succeeded the F7 model in GM-EMD's F-unit sequence. Final assembly was at GM-EMD's La Grange, Illinois plant. The F9 was also built in Canada by General Motors Diesel at their London, Ontario London is a city in southwestern Ontario, Canada, along the Quebec City–Windsor Corridor.

EMD F3
The EMD F3 is a B-B freight- and passenger-hauling carbody diesel locomotive produced between July 1945 and February 1949 by General Motors’ Electro-Motive Division. Final assembly was at GM-EMD's La Grange, Illinois plant. A total of 1,106 cab-equipped lead A units and 694 cabless booster B units were built. The F3 was the third model in GM-EMD's highly successful F-unit series of cab unit diesel locomotives, and it was the second most produced of the series. The F3 essentially differed from the EMD F2 in that it used the “new” D12 generator to produce more power and from the later EMD F7 in electrical equipment. Some late-model F3's had the same D27 traction motors, along with the heavier-duty electrical cables, used in the F7, and were referred to as model F5 by EMD's Engineering Department. Design The F3 used a 16-cylinder 567B series diesel engine developing at 800 rpm. The 567 was purpose-designed for locomotive service, and is a mechanically-aspira ...

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] |
Northlander
The ''Northlander'' was a passenger train operated by the provincially-owned Ontario Northland Railway in southern and northeastern Ontario, Canada. In 2012, rail service was discontinued and replaced with express bus service. Rail service will be reinstated in the mid-2020s with an expanded route, greater frequency, new Siemens Venture trainsets manufactured by Siemens Mobility, and various track and station upgrades. The new bi-directional route will run up to seven days a week from Toronto Union Station to Timmins, with an additional new rail connection from Timmins to Cochrane (where passengers can then connect directly to the Polar Bear Express at Cochrane Station) and express bus service from Matheson to Cochrane Station. Prior to 2012, the ''Northlander'' operated six days per week year-round in both directions and connected Cochrane with Toronto. The train typically consisted of one engine, an auxiliary power unit, two coaches and a cafeteria lounge car. It ran on ON ...
