SD26
The SD26 were EMD SD24 diesel locomotives rebuilt by the Atchison, Topeka and Santa Fe Railway between January 1973 and January 1978. In an effort to spare the cost of purchasing new motive power, the Santa Fe elected to expand on the success of its CF7 and other capital rebuild programs and extend the life of its fleet of 80 aging SD24s by rebuilding them at its San Bernardino, California Shops. The rebuilt locomotives saw service throughout much of the Santa Fe system. One unit, the 4625, was wrecked in August 1974 shortly after rebuild. Another 44 units were retired by Santa Fe in 1985 and replaced with state-of-the-art equipment, while a year later the remaining 35 units were sold to Guilford Rail System (now Pan Am Railways). As of 2012, all SD26s have been scrapped. History Development The first locomotive to go through the rebuild program was Santa Fe #4533, which entered the San Bernardino shops in January 1973. Its four roof-mounted "torpedo tube" air reservoir tanks wer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EMD SD24
The EMD SD24 was a six-axle ( C-C) diesel-electric locomotive built by General Motors' Electro-Motive Division of La Grange, Illinois between July 1958 and March 1963. A total of 224 units were built for customers in the United States, comprising 179 regular, cab-equipped locomotives and 45 cabless B units. The latter were built solely for the Union Pacific Railroad. The SD24 was the first EMD production locomotive to be built with an EMD turbocharged diesel engine. The first SD24 was built sixteen months before the four-axle ( B-B) model GP20. Power output of the SD24 was 33 percent higher than the of the concurrent Roots blower-equipped SD18s with the same engine displacement. The SD24 had per axle, limited by the traction motors then available. Nevertheless, the turbocharged SD24 provided full rated power at all altitudes, which the Roots-blown SD18 could not provide. In terms of sales, the SD24 was only a moderate success, and had average service lives in SD24 confi ... [...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 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 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 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 Tugboats. Its bus line extended passenger transportation to areas not ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electro-Motive Diesel
Progress Rail Locomotives, doing business as Electro-Motive Diesel (EMD), is an American manufacturer of diesel-electric locomotives, locomotive products and diesel engines for the rail industry. The company is owned by Caterpillar through its subsidiary Progress Rail. Electro-Motive Diesel traces its roots to the Electro-Motive Engineering Corporation, a designer and marketer of gasoline-electric self-propelled rail cars founded in 1922 and later renamed Electro-Motive Company (EMC). In 1930, General Motors purchased Electro-Motive Company and the Winton Engine Co., and in 1941 it expanded EMC's realm to locomotive engine manufacturing as Electro-Motive Division (EMD). In 2005, GM sold EMD to Greenbriar Equity Group and Berkshire Partners, which formed Electro-Motive Diesel to facilitate the purchase. In 2010, Progress Rail completed the purchase of Electro-Motive Diesel from Greenbriar, Berkshire, and others. EMD's headquarters, engineering facilities and parts manufactur ...

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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intermodal Freight Transport
Intermodal freight transport involves the transportation of freight in an intermodal container or vehicle, using multiple modes of transportation (e.g., rail, ship, aircraft, and truck), without any handling of the freight itself when changing modes. The method reduces cargo handling, and so improves security, reduces damage and loss, and allows freight to be transported faster. Reduced costs over road trucking is the key benefit for inter-continental use. This may be offset by reduced timings for road transport over shorter distances. Origins Intermodal transportation has its origin in 18th century England and predates the railways. Some of the earliest containers were those used for shipping coal on the Bridgewater Canal in England in the 1780s. Coal containers (called "loose boxes" or "tubs") were soon deployed on the early canals and railways and were used for road/rail transfers (road at the time meaning horse-drawn vehicles). Wooden coal containers were first used on the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unit Train
A unit train, also called a block train or a trainload service, is a train in which all cars (wagons) carry the same commodity and are shipped from the same origin to the same destination, without being split up or stored en route. They are distinct from wagonload trains, which comprise differing numbers of cars for various customers. Unit trains enable railways to compete more effectively with road and internal waterway transport systems. Time and money is saved by avoiding the complexities and delays that would otherwise be involved with assembling and disassembling trains at rail yards near the origin and destination. Unit trains are particularly efficient and economical for high-volume commodities. Since they often carry only one commodity, cars are of all the same type; often the cars are identical. Use Unit trains are typically used for the transportation of bulk goods. These can be solid substances such as: * Track ballast or gravel * Iron ore from mines to ports or s ...

Sulfur
Sulfur (or sulphur in British English) is a chemical element with the symbol S and atomic number 16. It is abundant, multivalent and nonmetallic. Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula S8. Elemental sulfur is a bright yellow, crystalline solid at room temperature. Sulfur is the tenth most abundant element by mass in the universe and the fifth most on Earth. Though sometimes found in pure, native form, sulfur on Earth usually occurs as sulfide and sulfate minerals. Being abundant in native form, sulfur was known in ancient times, being mentioned for its uses in ancient India, ancient Greece, China, and ancient Egypt. Historically and in literature sulfur is also called brimstone, which means "burning stone". Today, almost all elemental sulfur is produced as a byproduct of removing sulfur-containing contaminants from natural gas and petroleum.. Downloahere The greatest commercial use of the element is the production ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wheat
Wheat is a grass widely cultivated for its seed, a cereal grain that is a worldwide staple food. The many species of wheat together make up the genus ''Triticum'' ; the most widely grown is common wheat (''T. aestivum''). The archaeological record suggests that wheat was first cultivated in the regions of the Fertile Crescent around 9600 BCE. Botanically, the wheat kernel is a type of fruit called a caryopsis. Wheat is grown on more land area than any other food crop (, 2014). World trade in wheat is greater than for all other crops combined. In 2020, world production of wheat was , making it the second most-produced cereal after maize. Since 1960, world production of wheat and other grain crops has tripled and is expected to grow further through the middle of the 21st century. Global demand for wheat is increasing due to the unique viscoelastic and adhesive properties of gluten proteins, which facilitate the production of processed foods, whose consumption is i ...

Coal
Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous ( Pennsylvanian) and Permian times. Many significant coal deposits are younger than this and originate from the Mesozoic and Cenozoic eras. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energy and over a third of its electricity. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barstow, California
Barstow is a city in San Bernardino County, California, in the Mojave Desert of Southern California. Located in the Inland Empire region of California, the population was 25,415 at the 2020 census. Barstow is an important crossroads for the Inland Empire and home to Marine Corps Logistics Base Barstow. History The settlement of Barstow began in the late 1840s in the Mormon Corridor. Every fall and winter, as the weather cooled, the rain produced new grass growth and replenished the water sources in the Mojave Desert. People, goods, and animal herds would move from New Mexico and later Utah to Los Angeles, along the Old Spanish Trail from Santa Fe, or after 1848, on the Mormon Road from Salt Lake City. Trains of freight wagons traveled back to Salt Lake City and other points in the interior. These travelers followed the course of the Mojave River, watering and camping at Fish Ponds on its south bank (west of Nebo Center) or 3.625 miles up river on the north bank, at a rive ...
