EMD SD39
An SD39 is a 6-axle diesel-electric locomotive built by General Motors Electro-Motive Division between August 1968 and May 1970. 54 were built for American railroads. In 1966 EMD replaced all their old models with new ones having the new 645 diesel. These included six-axle models SD38, SD40, SDP40 and SD45; the SD39 was added in 1968. All shared standard components including the frame, cab, traction alternator, trucks, traction motors, and air brakes. The difference was the power output: SD38 = from a non-turbocharged V16, SD39 = from a turbocharged V12, SD40 = from a turbocharged V16, and SD45 = from a turbocharged V20. The SD39 had the smallest prime mover and therefore had the most unused space above the frame, inside the hood between the main generator and electrical cabinet, and outside in large end "porches". Variant A variant was the SDL39, ordered by the Milwaukee Road The Chicago, Milwaukee, St. Paul and Pacific Railroad (CMStP&P), often referre ...

Alternator
An alternator is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current. For reasons of cost and simplicity, most alternators use a rotating magnetic field with a stationary armature.Gordon R. Selmon, ''Magnetoelectric Devices'', John Wiley and Sons, 1966 no ISBN pp. 391-393 Occasionally, a linear alternator or a rotating armature with a stationary magnetic field is used. In principle, any AC electrical generator can be called an alternator, but usually the term refers to small rotating machines driven by automotive and other internal combustion engines. An alternator that uses a permanent magnet for its magnetic field is called a magneto. Alternators in power stations driven by steam turbines are called turbo-alternators. Large 50 or 60 Hz three-phase alternators in power plants generate most of the world's electric power, which is distributed by electric power grids. History Alternating current generating ...

EMD Dash 2
The EMD Dash 2 is a line of diesel-electric locomotives introduced by General Motors' Electro-Motive Division (EMD) on January 1, 1972. Designations of these models were those of the former models with "-2" added (e.g., the SD40 was replaced by the SD40-2). They retained the basic specifications of the earlier models in terms of power output and most other features, but introduced a number of improvements to the locomotives' internal systems, specifically the electrical systems and the trucks of the locomotives. These were intended to improve availability, efficiency, and ease of maintenance. One major improvement was a modularized electrical control cabinet, allowing maintenance by unit replacement and the use of common parts. These concepts were first tested on the DDA40X. Changes Minor externally visible changes common across the whole line include the following: * Modified trucks with damping struts. Four-axle trucks have damping struts on two diagonally opposite corners. Si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southern Pacific Transportation Company
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 ...

Minneapolis, Northfield And Southern Railway
The Minneapolis, Northfield and Southern Railway was an long American shortline railroad connecting Minneapolis and Northfield, Minnesota. It was incorporated in 1918 to take over the trackage of the former Minneapolis, St. Paul, Rochester and Dubuque Electric Traction Company, also known as the Dan Patch Lines. On June 2, 1982, it was acquired by the Soo Line Railroad, which operated it as a separate railroad until merging it on January 1, 1986 along with the Chicago, Milwaukee, St. Paul and Pacific Railroad (Milwaukee Road). Until around 1963, it was a Class I railroad; in 1967, it reported 131 million ton-miles of revenue freight on of railroad. The Dan Patch Lines Marion W. Savage, owner of the race horse Dan Patch, planned an electric railroad that would connect the Twin Cities to his farm and stables south of the Minnesota River. Savage purchased Dan Patch for $62,000 (a fortune in 1902), then lavishly promoted his equine protégé. Savage and his backers chose 54th ...

Illinois Terminal Railroad
The Illinois Terminal Railroad Company (reporting marks "ITC"), known as the Illinois Traction System until 1937, was a heavy duty interurban electric railroad with extensive passenger and freight business in central and southern Illinois from 1896 to 1956. When Depression era Illinois Traction was in financial distress and had to reorganize, the Illinois Terminal name was adopted to reflect the line's primary money making role as a freight interchange link to major steam railroads at its terminal ends, Peoria, Danville, and St. Louis. Interurban passenger service slowly was reduced, ending in 1956. Freight operation continued but was hobbled by tight street running in some towns requiring very sharp radius turns. In 1956, ITC was absorbed by a consortium of connecting railroads. History ITC was a successor in interest to a series of interurban railroads that were consolidated in the early 1900s by businessman William B. McKinley into the ''Illinois Traction System'' (ITS), an ... [...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 larger railroads in the United States. The railroad was chartered in February 1859 to serve the cities of Atchison, Kansas, Atchison and Topeka, Kansas, and Santa Fe, New Mexico. The railroad reached the Kansas–Colorado border in 1873 and Pueblo, Colorado, in 1876. To create a demand for its services, the railroad set up real estate offices and sold farmland from the land grants that it was awarded by United States Congress, Congress. Despite being chartered to serve the city, the railroad chose to bypass Santa Fe, due to the engineering challenges of the mountainous terrain. Eventually Santa Fe Southern Railway, a branch line from Lamy, New Mexico, brought the Santa Fe railroad to its namesake city. 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 fleet of Santa Fe Railroad Tugboa ...

EMD SDL39
The EMD SDL39 is a model of 6-axle diesel-electric locomotive built by General Motors Electro-Motive Division between March 1969 and November 1972. Power was provided by the EMD 645E3 12-cylinder engine as used in the EMD GP39 which generated 2,300 horsepower (1.7 MW). The unit was built on a short frame with C-C export trucks, barely tipping the scales at and managing a light-footed axle-loading of just per axle. All 10 examples of this locomotive model were built for Milwaukee Road, who wanted a lightweight road-switcher to replace their fleet of 1947-built ALCO RSC-2s. These Milwaukee Road units were numbered 581–590. The 581 was wrecked at Sacred Heart, MN in 1983, and scrapped the following year. The remaining nine units were transferred to the Soo Line Railroad when it acquired the Milwaukee Road. All were subsequently included in the sale of the Soo's Lakes States Division (most of its network in Wisconsin and Upper Michigan, plus some lines in adjoining Illinois and ...

V20 Engine
V, or v, is the twenty-second and fifth-to-last letter in the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''vee'' (pronounced ), plural ''vees''. History The letter V ultimately comes from the Phoenician letter ''waw'' by way of U. See U for details. During the Late Middle Ages, two minuscule glyphs of U developed which were both used for sounds including and modern . The pointed form "v" was written at the beginning of a word, while a rounded form "u" was used in the middle or end, regardless of sound. So whereas "valour" and "excuse" appeared as in modern printing, "have" and "upon" were printed as "haue" and "vpon". The first distinction between the letters "u" and "v" is recorded in a Gothic script from 1386, where "v" preceded "u". By the mid-16th century, the "v" form was used to represent the consonant and "u" the vowel sound, giving us the modern letter V. ...
