EMD GP50
An EMD GP50 is a 4-axle diesel-electric locomotive built by General Motors Electro-Motive Division (EMD). It is powered by a 16-cylinder EMD 645F3B diesel engine, which can produce between . 278 examples of this locomotive were built by EMD between 1980 and 1985. BN 3110-3162 were all delivered with five cab seats, the final five of these having the cab lengthened vs. the standard EMD cab. The GP50 retains the same overall length of as the GP38, GP39, and GP40 series locomotives. In 2015–2016 the Norfolk Southern Railway rebuilt 28 of their GP50s into the low-emission GP33ECO. And in early 2016, Norfolk Southern rebuilt one GP50 into their first GP59ECO. These units, most of which utilized GP59 cores, have similar specifications as the earlier GP33ECO program but have been built without public funding contributing to their construction. History EMD delivered the first GP50s to Chicago Northwestern in the summer of 1980. Much of the GP50's new technology was tested and ...

Chicago And North Western Transportation Company
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 ...

Southern Railway (US)
The Southern Railway (also known as Southern Railway Company and now known as the Norfolk Southern Railway) was a class 1 railroad based in the Southern United States between 1894 and 1982, when it merged with the Norfolk & Western to form Norfolk Southern. The railroad was the product of nearly 150 predecessor lines that were combined, reorganized and recombined beginning in the 1830s, formally becoming the Southern Railway in 1894. At the end of 1971, the Southern operated of railroad, not including its Class I subsidiaries Alabama Great Southern (528 miles or ); Central of Georgia (1729 miles); Savannah & Atlanta (167 miles); Cincinnati, New Orleans and Texas Pacific Railway (415 miles); Georgia Southern & Florida (454 miles); and twelve Class II subsidiaries. That year, the Southern itself reported 26,111 million net ton-miles of revenue freight and 110 million passenger-miles.

Missouri Pacific Railroad
The Missouri Pacific Railroad , commonly abbreviated as MoPac, was one of the first railroads in the United States west of the Mississippi River. MoPac was a Class I railroad growing from dozens of predecessors and mergers. In 1967, the railroad operated 9,041 miles of road and 13,318 miles of track, not including DK&S, NO&LC, T&P, and its subsidiaries C&EI and Missouri-Illinois. Union Pacific Corporation, the parent company of the Union Pacific Railroad, agreed to buy the Missouri Pacific Railroad on January 8, 1980. Lawsuits filed by competing railroads delayed approval of the merger until September 13, 1982. After the Supreme Court denied a trial to the Southern Pacific, the merger took effect on December 22, 1982. However, due to outstanding bonds of the Missouri Pacific, its full merger into the Union Pacific Railroad did not become official until January 1, 1997. History On July 4, 1851, ground was broken at St. Louis on the Pacific Railroad, the predecessor of the M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Union Pacific Railroad
The Union Pacific Railroad , legally Union Pacific Railroad Company and often called simply Union Pacific, is a freight-hauling railroad that operates 8,300 locomotives over routes in 23 U.S. states west of Chicago and New Orleans. Union Pacific is the second largest railroad in the United States after BNSF, with which it shares a duopoly on transcontinental freight rail lines in the Western, Midwestern and Southern United States. Founded in 1862, the original Union Pacific Rail Road was part of the first transcontinental railroad project, later known as the Overland Route. Over the next century, UP absorbed the Missouri Pacific Railroad, the Chicago and North Western Transportation Company, the Western Pacific Railroad, the Missouri–Kansas–Texas Railroad and the Chicago, Rock Island and Pacific Railroad. In 1996, the Union Pacific merged with Southern Pacific Transportation Company, itself a giant system that was absorbed by the Denver and Rio Grande Western Railroad ...

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 ...

Doppler Radar
A Doppler radar is a specialized radar that uses the Doppler effect to produce velocity data about objects at a distance. It does this by bouncing a microwave signal off a desired target and analyzing how the object's motion has altered the frequency of the returned signal. This variation gives direct and highly accurate measurements of the radial component of a target's velocity relative to the radar. Concept Doppler effect The Doppler effect (or Doppler shift), named after Austrian physicist Christian Doppler who proposed it in 1842, is the difference between the observed frequency and the emitted frequency of a wave for an observer moving relative to the source of the waves. It is commonly heard when a vehicle sounding a siren approaches, passes and recedes from an observer. The received frequency is higher (compared to the emitted frequency) during the approach, it is identical at the instant of passing by, and it is lower during the recession. This variation of f ...
