Railway Services Introduced In 1960
Rail transport (also known as train transport) is a means of transport using wheeled vehicles running in tracks, which usually consist of two parallel steel rails. Rail transport is one of the two primary means of land transport, next to road transport. It is used for about 8% of passenger and freight transport globally, thanks to its energy efficiency and potentially high speed.Rolling stock on rails generally encounters lower frictional resistance than rubber-tyred road vehicles, allowing rail cars to be coupled into longer trains. Power is usually provided by diesel or electric locomotives. While railway transport is capital-intensive and less flexible than road transport, it can carry heavy loads of passengers and cargo with greater energy efficiency and safety. Precursors of railways driven by human or animal power have existed since antiquity, but modern rail transport began with the invention of the steam locomotive in the United Kingdom at the beginning of the 19th ...

Alaska Railroad Oil Train At Nenna
Alaska ( ) is a Non-contiguous United States, non-contiguous U.S. state on the northwest extremity of North America. Part of the Western United States region, it is one of the two non-contiguous U.S. states, alongside Hawaii. Alaska is also considered to be the northernmost, westernmost, and easternmost (the Aleutian Islands cross the 180th meridian into the eastern hemisphere) state in the United States. It borders the Provinces and territories of Canada, Canadian territory of Yukon and the Provinces and territories of Canada, province of British Columbia to the east. It shares a western maritime border, in the Bering Strait, with Russia's Chukotka Autonomous Okrug. The Chukchi Sea, Chukchi and Beaufort Sea, Beaufort Seas of the Arctic Ocean lie to the north, and the Pacific Ocean lies to the south. Technically, it is a enclave and exclave, semi-exclave of the U.S., and is the largest exclave in the world. Alaska is the list of U.S. states and territories by area, largest U ...

Aviation
Aviation includes the activities surrounding mechanical flight and the aircraft industry. ''Aircraft'' include fixed-wing and rotary-wing types, morphable wings, wing-less lifting bodies, as well as lighter-than-air aircraft such as hot air balloons and airships. Aviation began in the 18th century with the development of the hot air balloon, an apparatus capable of atmospheric displacement through buoyancy. Clément Ader built the "Ader Éole" in France and made an uncontrolled, powered hop in 1890. This was the first powered aircraft, although it did not achieve controlled flight. Some of the most significant advancements in aviation technology came with the controlled gliding flying of Otto Lilienthal in 1896. A major leap followed with the construction of the '' Wright Flyer'', the first powered airplane by the Wright brothers in the early 1900s. Since that time, aviation has been technologically revolutionized by the introduction of the jet engine which enabl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rapid Transit
Rapid transit or mass rapid transit (MRT) or heavy rail, commonly referred to as metro, is a type of high-capacity public transport that is generally built in urban areas. A grade separation, grade separated rapid transit line below ground surface through a tunnel can be regionally called a subway, tube, metro or underground. They are sometimes grade-separated on elevated railways, in which case some are referred to as el trains – short for "elevated" – or skytrains. Rapid transit systems are usually electric railway, electric railways, that unlike buses or trams operate on an exclusive right-of-way (transportation), right-of-way, which cannot be accessed by pedestrians or other vehicles. Modern services on rapid transit systems are provided on designated lines between metro station, stations typically using electric multiple units on railway tracks. Some systems use rubber-tyred metro, guided rubber tires, magnetic levitation (''maglev''), or monorail. The stations typica ...

Tram
A tram (also known as a streetcar or trolley in Canada and the United States) is an urban rail transit in which Rolling stock, vehicles, whether individual railcars or multiple-unit trains, run on tramway tracks on urban public streets; some include segments on segregated Right-of-way (property access), right-of-way. The tramlines or tram networks operated as public transport are called tramways or simply trams/streetcars. Because of their close similarities, trams are commonly included in the wider term ''light rail'', which also includes systems separated from other traffic. Tram vehicles are usually lighter and shorter than Main line (railway), main line and rapid transit trains. Most trams use electrical power, usually fed by a Pantograph (transport), pantograph sliding on an overhead line; older systems may use a trolley pole or a bow collector. In some cases, a contact shoe on a third rail is used. If necessary, they may have dual power systems—electricity in city stre ...

Railway Electrification
Railway electrification is the use of electric power for the propulsion of rail transport. Electric railways use either electric locomotives (hauling passengers or Rail freight transport, freight in separate cars), electric multiple units (Passenger car (rail), passenger cars with their own motors) or both. Electricity is typically generated in large and relatively efficient electric power station, generating stations, transmitted to the railway network and distributed to the trains. Some electric railways have their own dedicated generating stations and electric transmission line, transmission lines, but most purchase power from an electric utility. The railway usually provides its own distribution lines, switches, and transformers. Power is supplied to moving trains with a (nearly) continuous electrical conductor, conductor running along the track that usually takes one of two forms: an overhead line, suspended from poles or towers along the track or from structure or tunnel cei ...

Great American Desert
The term Great American Desert was used in the 19th century to describe the part of North America east of the Rocky Mountains to approximately the 100th meridian west, 100th meridian. It can be traced to Stephen Harriman Long, Stephen H. Long's Stephen H. Long's Expedition of 1820, 1820 scientific expedition which put the Great American Desert on the map. Today the area is usually referred to as the High Plains (United States), High Plains, and the original term is sometimes used to describe the List of North American deserts, arid region of North America, which includes parts of northwestern Mexico and the Southwestern United States, American southwest. The concept of "desert" The meaning of the term "desert" has varied through time and across cultures. The term was sometimes used to describe any uninhabited or treeless land, whether or not it was arid, and sometimes to refer to hot and arid lands, evoking images of sandy wastelands. European colonists believed that treeless la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rail Transportation In The United States
Rail transportation in the United States consists primarily of Rail freight transport, freight shipments along a well integrated network of Standard-gauge railway, standard gauge private freight railroads that also extend into Canada and Mexico. The United States has the List of countries by rail transport network size, largest rail transport network of any country in the world, about . Passenger train, Passenger service is a Public transport, mass transit option for Americans with commuter rail in most major American cities, especially on the East Coast of the United States, East Coast. Intercity passenger service was once a large and vital part of the nation's passenger transportation network, but passenger service shrank in the 20th century as Aviation in the United States, commercial air traffic and the Interstate Highway System made commercial air and road transport a practical option throughout the United States. The nation's earliest railroads were built in the 1820s and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shipping
Freight transport, also referred to as freight forwarding, is the physical process of transporting commodities and merchandise goods and cargo. The term shipping originally referred to transport by sea but in American English, it has been extended to refer to transport by land or air (International English: "carriage") as well. "Logistics", a term borrowed from the military environment, is also used in the same sense. History Prehistoric Era Initial human civilization relied heavily on domesticated animals, such as horses, camels, and donkeys, to transport their goods. The invention of the wheel in Mesopotamia in 5000BC improved this efficiency by allowing for carts and carriages to be created, which animals could pull. Classical Era Romans The Romans built a vast network of roads, which facilitated trade across the numerous cities in its empire. Silk Road Transport along the silk road, a land-based route, was generally done through caravans, equipped ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Industrial Revolution
The Industrial Revolution, sometimes divided into the First Industrial Revolution and Second Industrial Revolution, was a transitional period of the global economy toward more widespread, efficient and stable manufacturing processes, succeeding the Second Agricultural Revolution. Beginning in Kingdom of Great Britain, Great Britain around 1760, the Industrial Revolution had spread to continental Europe and the United States by about 1840. This transition included going from craft production, hand production methods to machines; new Chemical industry, chemical manufacturing and Puddling (metallurgy), iron production processes; the increasing use of Hydropower, water power and Steam engine, steam power; the development of machine tools; and rise of the mechanisation, mechanised factory system. Output greatly increased, and the result was an unprecedented rise in population and population growth. The textile industry was the first to use modern production methods, and textiles b ...
