Navajo Mine And Railroad
The Navajo Mine is a surface coal mine owned and operated by Navajo Transitional Energy Company (NTEC) in New Mexico, United States, within the Navajo Nation. The mine is about southwest of Farmington, New Mexico. The Navajo Mine Railroad has of track between the Four Corners Generating Station and Navajo Mine. History Navajo Mine's coal lease was granted in 1957. In 1963, Navajo Mine began operations for Utah International. The Navajo Mine is the sole supplier of coal to the adjacent Four Corners Power Plant (FCPP). In 1977 General Electric acquired Navajo Mine from Utah International. Seven years later in 1984, BHP acquired Navajo Mine. In 2013, the 22nd Navajo Nation Council created Navajo Transitional Energy Company (NTEC), under legislation No. 0116-13 with a vote of 7-4. By the end of that year, NTEC acquired Navajo Mine. NTEC received a lease extension through the Department of the Interior and the Office of Surface Mining Reclamation & Enforcement (OSMRE) for 25-year s ...

Rail Freight Transport
Rail freight transport is the use of railways and trains to transport cargo as opposed to human passengers. A freight train, cargo train, or goods train is a group of freight cars (US) or goods wagons (International Union of Railways) hauled by one or more locomotives on a railway, transporting cargo all or some of the way between the shipper and the intended destination as part of the logistics chain. Trains may haul bulk material handling, bulk material, intermodal containers, general freight or specialized freight in purpose-designed cars. Rail freight practices and economics vary by country and region. When considered in terms of ton-miles or tonne-kilometers hauled, Energy efficiency in transport#Trains, energy efficiency can be greater with rail transportation than with other means. Maximum economies are typically realized with bulk commodities (e.g., coal), especially when hauled over long distances. Moving goods by rail often involves transshipment costs, particularly ...

Air Filter
A particulate air filter is a device composed of fibrous, or porous materials which removes particulates such as smoke, dust, pollen, mold, viruses and bacteria from the air. Filters containing an adsorbent or catalyst such as charcoal (carbon) may also remove odors and gaseous pollutants such as volatile organic compounds or ozone. Air filters are used in applications where air quality is important, notably in building ventilation systems and in engines. Some buildings, as well as aircraft and other human-made environments (e.g., satellites, and Space Shuttles) use foam, pleated paper, or spun fiberglass filter elements. Another method, air ionizers, use fibers or elements with a static electric charge, which attract dust particles. The air intakes of internal combustion engines and air compressors tend to use either paper, foam, or cotton filters. Oil bath filters have fallen out of favour aside from niche uses. The technology of air intake filters of gas turbines has impr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wabash Railroad
The Wabash Railroad was a Class I railroad that operated in the mid-central United States. It served a large area, including track in the states of Ohio, Indiana, Illinois, Iowa, Michigan, and Missouri and the province of Ontario. Its primary connections included Chicago, Illinois; Kansas City, Missouri; Detroit, Michigan; Buffalo, New York; St. Louis, Missouri; and Toledo, Ohio. The Wabash's major freight traffic advantage was the direct line from Kansas City to Detroit, without going through St. Louis or Chicago. Despite being merged into the Norfolk and Western Railway (N&W) in 1964, the Wabash company continued to exist on paper until the N&W merged into the Norfolk Southern Railway (NS) in 1982. At the end of 1960 Wabash operated 2,423 miles of road on 4,311 miles of track, not including Ann Arbor Railroad (1895–1976), the Ann Arbor Railroad and the New Jersey, Indiana and Illinois Railroad; that year it reported 6,407 million net ton-miles of revenue freight and 164& ...

Norfolk & Western
The Norfolk and Western Railway , commonly called the N&W, was a US class I railroad, formed by more than 200 railroad mergers between 1838 and 1982. It was headquartered in Roanoke, Virginia, for most of its existence. Its motto was "Precision Transportation"; it had a variety of nicknames, including "King Coal" and "British Railway of America". In 1986, N&W merged with Southern Railway to form today's Norfolk Southern Railway. The N&W was famous for manufacturing its own steam locomotives, which were built at the Roanoke Shops, as well as its own hopper cars. After 1960, N&W was the last major Class I railroad using steam locomotives; the last remaining Y class 2-8-8-2s would eventually be retired in 1961. In December 1959, the N&W merged with the Virginian Railway (reporting mark VGN), a longtime rival in the Pocahontas coal region. By 1970, other mergers with the Nickel Plate Road and Wabash formed a system that operated of road on of track from North Carolina to New ...

Loader (equipment)
A loader is a heavy equipment machine used in construction to move or load materials such as soil, rock, sand, demolition debris, etc. into or onto another type of machinery (such as a dump truck, conveyor belt, feed-hopper, or railroad car). There are many types of loader, which, depending on design and application, are variously called a bucket loader, end loader, front loader, front-end loader, payloader, high lift, scoop, shovel dozer, skid-steer, skip loader, tractor loader or wheel loader. Description A loader is a type of tractor, usually wheeled, sometimes on tracks, that has a front-mounted wide bucket connected to the end of two booms (arms) to scoop up loose material from the ground, such as dirt, sand or gravel, and move it from one place to another without pushing the material across the ground. A loader is commonly used to move a stockpiled material from ground level and deposit it into an awaiting dump truck or into an open trench excavation. The loade ...

Railfan & Railroad
''Railfan & Railroad'' is an American monthly magazine that has been in publication since the 1970s. It was the first magazine title established in-house by Carstens Publications. As a magazine dedicated to trains and rail transportation, it stands out from its main competitor ''Trains'' as a publication focused on the enthusiast and related activities. Established in 1974 as ''Railfan'' magazine (ISSN 0098-0714), it merged in 1979 with ''Railroad'' magazine, which Carstens purchased at that time. The magazine was renamed ''Railfan & Railroad'', but the two former titles were listed separately on the masthead until 2015. The magazine was acquired by White River Productions in September 2014. The magazine is produced monthly, edited by Steve Barry. Founding and early days As early as 1968, future '' Railroad Model Craftsman'' editor Tony Koester visited publisher Harold Carstens to pitch an idea for a "railfan's" magazine, at the insistence of his friend Jim Boyd (who was at t ...

Catenary
In physics and geometry, a catenary ( , ) is the curve that an idealized hanging chain or wire rope, cable assumes under its own weight when supported only at its ends in a uniform gravitational field. The catenary curve has a U-like shape, superficially similar in appearance to a parabola, which it is not. The curve appears in the design of certain types of Catenary arch, arches and as a cross section of the catenoid—the shape assumed by a soap film bounded by two parallel circular rings. The catenary is also called the alysoid, chainette,#MathWorld, MathWorld or, particularly in the materials sciences, an example of a funicular curve, funicular. Rope statics describes catenaries in a classic statics problem involving a hanging rope. Mathematically, the catenary curve is the Graph of a function, graph of the hyperbolic cosine function. The surface of revolution of the catenary curve, the catenoid, is a minimal surface, specifically a minimal surface of revolution. A ha ...

GE E60
The GE E60 is a family of six-axle C-C electric locomotives made by GE Transportation Systems (GE) between 1972 and 1983. The E60s were produced in several variants for both freight and passenger use in the United States and Mexico. GE designed the locomotive for use on the Black Mesa and Lake Powell Railroad (BM&LP), a dedicated coal-hauling route in Arizona, which began operation in 1973. That same year GE adapted the design for high-speed passenger service on Amtrak's Northeast Corridor. The largest customer was Ferrocarriles Nacionales de México (NdeM), the state-owned railroad in Mexico, which bought 39 for a new electrification project in the early 1980s. The E60s were successful in the coal-hauling role. They ran on the BM&LP for decades and remain in use on several mining railroads in the Western United States. The passenger variants failed in their intended role. Problems with the truck design caused derailments above , rendering the locomotives unusable for high-s ...

Kayenta Mine
The Kayenta mine was a surface coal mine operated by Peabody Western Coal Company, a subsidiary of Peabody Energy) on the Navajo Nation in northern Arizona from 1973 to 2019. About 400 acres were mined and reclaimed each year, providing about 8 million tons of coal annually to the Navajo Generating Station. History The Kayenta mine was located near the northern edge of Black Mesa, a 5,400 square mile highland plateau in northeast Arizona that contains extensive coal deposits in several geologic formations. Since about 1300 AD, the Hopi had extracted coal from the area for pottery firing and domestic heating. In the early 1900s, limited surveying of the coal field was made and a number of small underground mines were put into production, supplying local reservation schools and communities in the region. The coal field received increased attention beginning in 1950 when the Navajo-Hopi Long Range Rehabilitation Act was enacted in response to dire economic conditions on t ...
