History Of Rapid Transit
The history of rapid transit began in London with the opening of the Metropolitan Railway, which is now part of the London Underground, in 1863. By World War I, electric underground railways were being used in Athens Metro, Athens, Berlin U-Bahn, Berlin, Green Line (MBTA), Boston, Buenos Aires Underground, Buenos Aires, Budapest Metro, Budapest, Glasgow Subway, Glasgow, Hamburg U-Bahn, Hamburg, Metro Istanbul, Istanbul, Mersey Railway, Liverpool, New York City Subway, New York City, Paris Métro, Paris, and SEPTA, Philadelphia. In the 21st century, China became the world's leader by number of rapid transit systems as well as the fastest growth of such systems, and many other Asian countries began construction of their own rapid transit systems. Development While smoke was a major problem for urban railways in tunnels, it was less of a problem in steam-hauled elevated railways, the IRT Ninth Avenue Line, first of which opened in New York City in 1870. In 1890 London's City & S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Constructing The Metropolitan Railway
Construction are processes involved in delivering buildings, infrastructure, industrial facilities, and associated activities through to the end of their life. It typically starts with planning, financing, and design that continues until the asset is built and ready for use. Construction also covers repairs and maintenance work, any works to expand, extend and improve the asset, and its eventual demolition, dismantling or decommissioning. The construction industry contributes significantly to many countries' gross domestic products (GDP). Global expenditure on construction activities was about $4 trillion in 2012. In 2022, expenditure on the construction industry exceeded $11 trillion a year, equivalent to about 13 percent of global GDP. This spending was forecasted to rise to around $14.8 trillion in 2030. The construction industry promotes economic development and brings many non-monetary benefits to many countries, but it is one of the most hazardous industries. For exampl ...

District Railway
The Metropolitan District Railway, also known as the District Railway, was a passenger railway that served London, England, from 1868 to 1933. Established in 1864 to complete an " inner circle" of lines connecting railway termini in London, the first part of the line opened using gas-lit wooden carriages hauled by steam locomotives. The Metropolitan Railway operated all services until the District Railway introduced its own trains in 1871. The railway was soon extended westwards through Earl's Court to Fulham, Richmond, Ealing and Hounslow. After completing the inner circle and reaching Whitechapel in 1884, it was extended to Upminster in Essex in 1902. To finance electrification at the beginning of the 20th century, American financier Charles Yerkes took it over and made it part of his Underground Electric Railways Company of London (UERL) group. Electric propulsion was introduced in 1905, and by the end of the year electric multiple units operated all of the services. On ...

Cable Railway
A cable railway is a railway that uses a Wire rope, cable, rope or chain to haul trains. It is a specific type of cable transportation. The most common use for a cable railway is to move vehicles on a Grade (slope), steeply graded line that is too steep for conventional locomotives to operate on – this form of cable railway is often called an incline or inclined plane, or, in New Zealand, a jigline, or jig line. One common form of incline is the funicular – an isolated passenger railway where the cars are permanently attached to the cable.Walter Hefti: ''Schienenseilbahnen in aller Welt. Schiefe Seilebenen, Standseilbahnen, Kabelbahnen.'' Birkhäuser, Basel 1975, (in German) In other forms, the cars attach and detach to the cable at the ends of the cable railway. Some cable railways are not steeply graded - these are often used in quarries to move large numbers of wagons between the quarry to the processing plant. History The oldest extant cable railway is probably the Re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pneumatic Tube
Pneumatic tubes (or capsule pipelines, also known as pneumatic tube transport or PTT) are systems that propel cylindrical containers through networks of Tubing (material), tubes by Gas compressor, compressed air or by partial vacuum. They are used for transporting solid objects, as opposed to conventional pipelines which transport fluids. In the late 19th and early 20th centuries, pneumatic tube networks gained acceptance in offices that needed to transport small, urgent packages, such as mail, other paperwork, or money, over relatively short distances, within a building or, at most, within a city. Some installations became quite complex, but have mostly been superseded. However, they have been further developed in the 21st century in places such as hospitals, to send blood samples and the like to clinical laboratory, clinical laboratories for analysis. A small number of pneumatic transportation systems were built for larger cargo, to compete with train and subway systems. However ...

Cut And Cover
A tunnel is an underground or undersea passageway. It is dug through surrounding soil, earth or rock, or laid under water, and is usually completely enclosed except for the two portals common at each end, though there may be access and ventilation openings at various points along the length. A pipeline differs significantly from a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods. A tunnel may be for foot or vehicular road traffic, for rail traffic, or for a canal. The central portions of a rapid transit network are usually in the tunnel. Some tunnels are used as sewers or aqueducts to supply water for consumption or for hydroelectric stations. Utility tunnels are used for routing steam, chilled water, electrical power or telecommunication cables, as well as connecting buildings for convenient passage of people and equipment.Salazar, Waneta.

Liverpool Lime Street Railway Station
Liverpool Lime Street is a railway station complex located on Lime Street, Liverpool, Lime Street in Liverpool city centre. Although publicly a single, unified station, it is operationally divided into two official railway stations: Liverpool Lime Street High Level, the main station serving the city centre of Liverpool and the oldest still-operating grand terminus mainline station in the world; and Liverpool Lime Street Low Level, an underground Wirral line station (part of the List of underground stations of the Merseyrail network, Merseyrail network) connected to the main terminal building by a pedestrian subway below street-level. Despite their operational distinctions, both stations are integrated from a passenger perspective, sharing signage, access points and overall station identity. Lime Street High Level is one of 18 stations managed by Network Rail, while Lime Street Low Level is managed directly by the train operator, Merseyrail. A branch of the West Coast Mai ...

Crown Street Railway Station
Crown Street railway station was the Liverpool terminus railway station of the Liverpool and Manchester Railway in Liverpool, England, it opened on 15 September 1830. The station was one of the world's first on an inter-city passenger railway in which all services were operated by mechanical traction. The station was only used for passengers for six years before being replaced by which was closer to Liverpool City centre. The station was demolished as the site was converted into a coal and goods yard which remained in use until 1972. The location of the station is now a park with little trace of any railway facilities. Passenger station Opening The station was opened to the public on 17 September 1830, it a ceremonial opening as part of the opening of the railway on 15 September 1830, and there had been a charter train to Manchester and back for the Society of Friends to and from their quarterly meeting on 16 September 1830.

Pen-y-Darren (locomotive)
Richard Trevithick (13 April 1771 – 22 April 1833) was a British inventor and mining engineer. The son of a mining captain, and born in the mining heartland of Cornwall, Trevithick was immersed in mining and engineering from an early age. He was an early pioneer of steam-powered road and rail transport, and his most significant contributions were the development of the first high-pressure steam engine and the first working railway steam locomotive. The world's first locomotive-hauled railway journey took place on 21 February 1804, when Trevithick's unnamed steam locomotive hauled a train along the tramway of the Penydarren Ironworks, in Merthyr Tydfil, Wales. Turning his interests abroad Trevithick also worked as a mining consultant in Peru and later explored parts of Costa Rica. Throughout his professional career he went through many ups and downs and at one point faced financial ruin, also suffering from the strong rivalry of many mining and steam engineers of the day.

Grade (slope)
The grade (US) or gradient (UK) (also called stepth, slope, incline, mainfall, pitch or rise) of a physical feature, landform or constructed line is either the elevation angle of that surface to the horizontal plane, horizontal or its tangent. It is a special case of the slope, where zero indicates horizontal plane, horizontality. A larger number indicates higher or steeper degree of "tilt". Often slope is calculated as a ratio of "rise" to "run", or as a fraction ("rise over run") in which ''run'' is the horizontal distance (not the distance along the slope) and ''rise'' is the vertical distance. Slopes of existing physical features such as canyons and hillsides, bank (geography), stream and river banks, and stream bed, beds are often described as grades, but typically the word "grade" is used for human-made surfaces such as roads, landscape grading, roof pitches, rail tracks, railroads, aqueduct (watercourse), aqueducts, and pedestrian or bicycle routes. The grade may refer to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Electrification System
Railway electrification is the use of electric power for the propulsion of rail transport. Electric railways use either electric locomotives (hauling passengers or freight in separate cars), electric multiple units ( passenger cars with their own motors) or both. Electricity is typically generated in large and relatively efficient generating stations, transmitted to the railway network and distributed to the trains. Some electric railways have their own dedicated generating stations and 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 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 ceilings and contacted by a pantograph, or a third rail mounted at track level and contacted by a sliding " pickup ...
