London Underground Infrastructure
The railway infrastructure of the London Underground includes 11 lines, with 272 stations. There are two types of line on the London Underground: services that run on the sub-surface network just below the surface using larger trains, and the deep-level tube lines, that are mostly self-contained and use smaller trains. Most of the lines emerge on the surface outside the Central London area. The oldest trains currently in service on the Underground are 1972 Stock trains on the Bakerloo line. The Underground is electrified using a four-rail system, the DC traction supply being independent of the running rails. Planned improvements include new stations, line extensions and more lines with automatic train operation (ATO). Railway The total length of railway on the London Underground is and made up of the sub-surface network and the deep-tube lines. In 1971/72 it was re-measured in kilometres using Ongar as the zero point. Sub-surface network and deep-level tube lines The Cir ...

Rail Transport
Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer facilit ...

Jubilee Line
The Jubilee line is a London Underground line that runs between in east London and in the suburban north-west, via the Docklands, South Bank and West End. Opened in 1979, it is the newest line on the Underground network, although some sections of track date back to 1932 and some stations to 1879. The western section between and was previously a branch of the Metropolitan line and later the Bakerloo line, while the newly built line was completed in two major sections: initially in 1979 to , then in 1999 with an extension to Stratford. The later stations are larger and have special safety features, both aspects being attempts to future-proof the line. Following the extension to east London, serving areas once poorly connected to the Underground, the line has seen a huge growth in passenger numbers and is the third-busiest on the network (after the Northern and Central lines), with over 213 million passenger journeys in 2011/12. Between and the Jubilee line shares its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
London Borough Of Croydon
The London Borough of Croydon () is a London borough in south London, part of Outer London. It covers an area of . It is the southernmost borough of London. At its centre is the historic town of Croydon from which the borough takes its name; while other urban centres include Coulsdon, Purley, South Norwood, Norbury, New Addington and Thornton Heath. Croydon is mentioned in Domesday Book, and from a small market town has expanded into one of the most populous areas on the fringe of London. The borough is now one of London's leading business, financial and cultural centres, and its influence in entertainment and the arts contribute to its status as a major metropolitan centre. Its population is 386,710, making it the second largest London borough and fifteenth largest English district. The borough was formed in 1965 from the merger of the County Borough of Croydon with Coulsdon and Purley Urban District, both of which had been within Surrey. The local authority, Croydon Londo ...

London Borough Of Bromley
The London Borough of Bromley () is the southeasternmost of the London boroughs that make up Greater London, bordering the ceremonial county of Kent, which most of Bromley was part of before 1965. The borough's population is an estimated 332,336. It is named after Bromley, its principal town; other major towns are Penge, Hayes, West Wickham, Chislehurst, Beckenham and Orpington. The local authority is Bromley London Borough Council. Geography The borough is the largest in Greater London by area and occupies . The majority of the borough is Metropolitan Green Belt, including nearly all of the land south of the A232-A21 route between West Wickham and Pratt's Bottom. Consequently, it is also perhaps the most rural borough and contains more of the North Downs than any other, as that escarpment is broad between Bromley and Banstead. This is also reflected in its population density, which is the lowest of the 32 London boroughs. Most of the population lives in the north and west of t ...

River Thames
The River Thames ( ), known alternatively in parts as the River Isis, is a river that flows through southern England including London. At , it is the longest river entirely in England and the second-longest in the United Kingdom, after the River Severn. The river rises at Thames Head in Gloucestershire, and flows into the North Sea near Tilbury, Essex and Gravesend, Kent, via the Thames Estuary. From the west it flows through Oxford (where it is sometimes called the Isis), Reading, Henley-on-Thames and Windsor. The Thames also drains the whole of Greater London. In August 2022, the source of the river moved five miles to beyond Somerford Keynes due to the heatwave in July 2022. The lower reaches of the river are called the Tideway, derived from its long tidal reach up to Teddington Lock. Its tidal section includes most of its London stretch and has a rise and fall of . From Oxford to the Estuary the Thames drops by 55 metres. Running through some of the drier parts of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
London Boroughs
The London boroughs are the 32 local authority districts that together with the City of London make up the administrative area of Greater London; each is governed by a London borough council. The present London boroughs were all created at the same time as Greater London on 1 April 1965 by the ''London Government Act 1963'' and are a type of local government district. Twelve were designated as Inner London boroughs and twenty as Outer London boroughs. The City of London, the historic centre, is a separate ceremonial county and local government district that functions quite differently from a London borough. However, the two counties together comprise the administrative area of Greater London as well as the London Region, all of which is also governed by the Greater London Authority. The London boroughs have populations of between 150,000 and 400,000. Inner London boroughs tend to be smaller, in both population and area, and more densely populated than Outer London boroughs. ...

London Underground With Greater London Map
London is the capital and largest city of England and the United Kingdom, with a population of just under 9 million. It stands on the River Thames in south-east England at the head of a estuary down to the North Sea, and has been a major settlement for two millennia. The City of London, its ancient core and financial centre, was founded by the Romans as ''Londinium'' and retains its medieval boundaries.See also: Independent city ยง National capitals The City of Westminster, to the west of the City of London, has for centuries hosted the national government and parliament. Since the 19th century, the name "London" has also referred to the metropolis around this core, historically split between the counties of Middlesex, Essex, Surrey, Kent, and Hertfordshire, which largely comprises Greater London, governed by the Greater London Authority.The Greater London Authority consists of the Mayor of London and the London Assembly.

Cross-platform Interchange
A cross-platform interchange is a type of interchange between different lines at a metro (or other railway) station. The term originates with the London Underground; such layouts exist in other networks but are not commonly so named. In the United States, it is often referred to as a cross-platform transfer. This configuration occurs at a station with island platforms, with a single platform in between the tracks allocated to two directions of travel, or two side platforms between the tracks, connected by level corridors. The benefit of this design is that passengers do not need to use stairs to another platform level for transfer. A cross-platform interchange arrangement may be costly to build due to the complexity of rail alignment, especially if the railway designers also arrange the track with flyovers (which is typically done to increase efficiency). A typical bidirectional cross-platform interchange configuration consists of two outbound directions of two different lines ...

London Overground
London Overground (also known simply as the Overground) is a suburban rail network serving London and its environs. Established in 2007 to take over Silverlink Metro routes, (via archive.org). it now serves a large part of Greater London as well as the home county of Hertfordshire, with 113 stations on nine different routes. The Overground forms part of the United Kingdom's National Rail network but it is under the concession control and branding of Transport for London. Operation has been contracted to Arriva Rail London since 2016. TfL assigned orange as a mode-specific colour for the Overground in branding and publicity including the roundel, on the Tube map, trains and stations. History Pre-1999 Rail services in Great Britain are mostly run under franchises operated by private train operating companies, marketed together as National Rail. The concept of developing a network of orbital services around London goes back to the independently produced Ringrail proposals ...

Tunnelling Shield
A tunnelling shield is a protective structure used during the excavation of large, man-made tunnels. When excavating through ground that is soft, liquid, or otherwise unstable, there is a potential health and safety hazard to workers and the project itself from falling materials or a cave-in. A tunnelling shield can be used as a temporary support structure. It is usually in place for the short-term from when the tunnel section is excavated until it can be lined with a permanent support structure. The permanent structure may be made up of, depending on the period, bricks, concrete, cast iron, or steel. Although modern shields are commonly cylindrical, the first "shield", designed by Marc Isambard Brunel, was actually a large, rectangular, scaffold-like iron structure with three levels and twelve sections per level, with a solid load-bearing top surface. The structure protected the men from cave-ins as they laboured within it, digging the tunnel out in front of the shield. History ...

Waterloo & City Line
The Waterloo & City line, colloquially known as The Drain, is a London Underground shuttle line that runs between Waterloo and Bank with no intermediate stops. Its primary traffic consists of commuters from south-west London, Surrey and Hampshire arriving at Waterloo main line station and travelling forward to the City of London financial district. For this reason, the line has historically not operated on Sundays or public holidays, except in very limited circumstances. However, following the COVID-19 pandemic, the line is currently only open on weekdays. It is one of only two lines on the Underground network to run completely underground, the other being the Victoria line. Printed in turquoise on the Tube map, it is by far the shortest line on the Underground network, being long, with an end-to-end journey lasting just four minutes. In absolute terms, it is the least-used Tube line, carrying just over 15 million passengers annually. However, in terms of the average nu ...
