SD7
An SD7 is a 6-axle diesel locomotive built by Electro-Motive Diesel, General Motors Electro-Motive Division between May 1951 and November 1953. It had an EMD 567B 16-cylinder (engine), 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 B ...

Southern Pacific 1518
Southern Pacific Railroad (SP) number 1518 is an EMD SD7, and was the first ever SD series diesel locomotive, originally built in May 1951 as General Motors Electro-Motive Division's (EMD) prototype Demonstrator #990. Its road number 990 was in reference to EMD Engineering Department's project number 15990. It successfully completed numerous demonstration tours for EMD on several railroads before being completely overhauled and subsequently sold to Southern Pacific. During this overhaul at EMD's LaGrange, IL shops, the prime mover and electrical cabinet were refurbished and new wheelsets were installed. When 5308 was delivered to SP shortly thereafter, it was slightly different from all other SD7s in that it was their only SD7 to have dual control stands, a winterization hatch over its forward fan (a rare, early feature for SP at that time, but not entirely unbeknownst to them: several of their F7s and the odd GP20 also had them), and two single-bell Leslie A-200 horns mounted ...

Southern Pacific Railroad
The Southern Pacific (or Espee from the railroad initials- SP) was an American Class I railroad network that existed from 1865 to 1996 and operated largely in the Western United States. The system was operated by various companies under the names Southern Pacific Railroad, Southern Pacific Company and Southern Pacific Transportation Company. The original Southern Pacific began in 1865 as a land holding company. The last incarnation of the Southern Pacific, the Southern Pacific Transportation Company, was founded in 1969 and assumed control of the Southern Pacific system. The Southern Pacific Transportation Company was acquired in 1996 by the Union Pacific Corporation and merged with their Union Pacific Railroad. The Southern Pacific legacy founded hospitals in San Francisco, Tucson, and Houston. In the 1970s, it also founded a telecommunications network with a state-of-the-art microwave and fiber optic backbone. This telecommunications network became part of Sprint, a compa ...

Diesel Locomotive
A diesel locomotive is a type of railway locomotive in which the prime mover is a diesel engine. Several types of diesel locomotives have been developed, differing mainly in the means by which mechanical power is conveyed to the driving wheels. Early internal combustion locomotives and railcars used kerosene and gasoline as their fuel. Rudolf Diesel patented his first compression-ignition engine in 1898, and steady improvements to the design of diesel engines reduced their physical size and improved their power-to-weight ratios to a point where one could be mounted in a locomotive. Internal combustion engines only operate efficiently within a limited power band, and while low power gasoline engines could be coupled to mechanical transmissions, the more powerful diesel engines required the development of new forms of transmission. This is because clutches would need to be very large at these power levels and would not fit in a standard -wide locomotive frame, or wear too quic ...

EMD 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] |
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] |
Nevada Northern Railway
The Nevada Northern Railway was a railroad in the U.S. state of Nevada, built primarily to reach a major copper producing area in White Pine County, Nevada. The railway, constructed in 1905–06, extended northward about from Ely to connections with the Western Pacific Railroad at Shafter and Southern Pacific Railroad at Cobre. In 1967 NN reported 40 million net ton-miles of revenue freight on of line. History The Nevada Northern owes its beginnings to the discovery and development of large porphyry copper deposits near Ely early in the 20th century. Two of the region's largest mines (including the Robinson Mine) were purchased in 1902 by Mark Requa, president of the Eureka and Palisade Railroad in central Nevada. Requa then organized the White Pine Copper Company to develop his new properties, and it soon became evident that rail access to the isolated region would be essential to fully exploit the potential of the mines. Subsequent surveys indicated that the most pra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bogie
A bogie ( ) (in some senses called a truck in North American English) is a chassis or framework that carries a wheelset, attached to a vehicle—a modular subassembly of wheels and axles. Bogies take various forms in various modes of transport. A bogie may remain normally attached (as on many railroad cars and semi-trailers) or be quickly detachable (as the dolly in a road train or in railway bogie exchange); it may contain a suspension within it (as most rail and trucking bogies do), or be solid and in turn be suspended (as most bogies of tracked vehicles are); it may be mounted on a swivel, as traditionally on a railway carriage or locomotive, additionally jointed and sprung (as in the landing gear of an airliner), or held in place by other means (centreless bogies). In Scotland, the term is used for a child’s (usually home-made) wooden cart. While ''bogie'' is the preferred spelling and first-listed variant in various dictionaries, bogey and bogy are also used.

Denver And Rio Grande Western Railroad
The Denver & Rio Grande Western Railroad , often shortened to ''Rio Grande'', D&RG or D&RGW, formerly the Denver & Rio Grande Railroad, was an American Class I railroad company. The railroad started as a narrow-gauge line running south from Denver, Colorado, in 1870. It served mainly as a transcontinental bridge line between Denver, and Salt Lake City, Utah. The Rio Grande was also a major origin of coal and mineral traffic. The Rio Grande was the epitome of mountain railroading, with a motto of ''Through the Rockies, not around them'' and later ''Main line through the Rockies'', both referring to the Rocky Mountains. The D&RGW operated the highest mainline rail line in the United States, over the Tennessee Pass in Colorado, and the famed routes through the Moffat Tunnel and the Royal Gorge. At its height, in 1889, the D&RGW had the largest narrow-gauge railroad network in North America with of track interconnecting the states of Colorado, New Mexico, and Utah. Known for ...

Chicago And North Western Railway
The Chicago and North Western was a 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 the railroad to a mainline ...

Bessemer And Lake Erie Railroad
The Bessemer and Lake Erie Railroad is a class II railroad that operates in northwestern Pennsylvania and northeastern Ohio. The railroad's main route runs from the Lake Erie port of Conneaut, Ohio, to the Pittsburgh suburb of Penn Hills, Pennsylvania, a distance of . The original rail ancestor of the B&LE, the Shenango and Allegheny Railroad, began operation in October 1869. Rail operations were maintained continuously by various corporate descendants on the growing system that ultimately became the BLE in 1900. In 2004 BLE came under the ownership of the Canadian National Railway (CN) as part of CN's larger purchase of holding company Great Lakes Transportation. BLE is operated by CN as their Bessemer Subdivision. As a subsidiary of CN, BLE has been largely unchanged (though repainting of BLE locomotives into CN paint with "BLE" sub-lettering began in April 2015) and still does business as BLE. BLE locomotives, especially the former Southern Pacific SD40T-3 "Tunnel Motors", h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
