. Traffic congestion in the city and the surrounding areas had increased significantly in this period, partly due to the need for rail travellers to complete their journeys into the city centre by road. The idea of building an underground railway to link the City of London with the mainline terminals had first been proposed in the 1830s, but it was not until the 1850s that the idea was taken seriously as a solution to the traffic congestion problems.

 to the City of London Corporation at the time. Pearson had supported the idea of an underground railway in London for several years. He advocated plans for the demolition of the unhygienic slums which would be replaced by new accommodation for their inhabitants in the suburbs, with the new railway providing transportation to their places of work in the city centre. Although he was never directly involved in the running of the Metropolitan Railway, he is widely credited as being one of the first true visionaries behind the concept of underground railways. And in 1859 it was Pearson who persuaded the City of London Corporation to help fund the scheme. Work finally began in February 1860, under the guidance of chief engineer John Fowler. Pearson died before the work was completed.

The Metropolitan Railway opened on 10 January 1863. Within a few months of opening it was carrying over 26,000 passengers a day. The Hammersmith and City Railway

 in the north-west.

The early tunnels were dug mainly using cut-and-cover construction methods. This caused widespread disruption and required the demolition of several properties on the surface. The first trains were steam-hauled, which required effective ventilation to the surface. Ventilation shafts at various points on the route allowed the engines to expel steam and bring fresh air into the tunnels. One such vent is at Leinster Gardens, W2. In order to preserve the visual characteristics in what is still a well-to-do street, a five-foot-thick (1.5 m) concrete façade was constructed to resemble a genuine house frontage.

) was opened, operating services from Bank to Shepherd's Bush. It was nicknamed the "Twopenny Tube" for its flat fare and cylindrical tunnels; the "tube" nickname was eventually transferred to the Underground system as a whole. An interchange with the C&SLR was provided at Bank. Construction had also begun in August 1898 on the Baker Street & Waterloo Railway. However work on this railway came to a halt 18 months after it began when funds ran out.

Integration

In the early 20th century the presence of six independent operators running different Underground lines caused passengers substantial inconvenience; in many places passengers had to walk some distance above ground to change between lines. The costs associated with running such a system were also heavy, and as a result many companies looked to financiers who could give them the money they needed to expand into the lucrative suburbs as well as electrify the earlier steam operated lines. The most prominent of these was Charles Yerkes

 by 1907.

In early 1908, in an effort to increase passenger numbers, the underground railway operators agreed to promote their services jointly as "the Underground", publishing new adverts and creating a free publicity map of the network for the purpose. The map featured a key labelling the Bakerloo Railway, the Central London Railway, the City & South London Railway, the District Railway, the Great Northern & City Railway, the Hampstead Railway (the shortened name of the CCE&HR), the Metropolitan Railway and the Piccadilly Railway. Some other railways appeared on the map but with less prominence than the aforementioned lines. These included part of the ELR (although the map wasn't big enough to fit in the whole line) and the Waterloo and City Railway. As the latter was owned by a main line railway company it wasn't included in this early phase of integration. As part of the process, "The Underground" name appeared on stations for the first time and electric ticket-issuing machines were also introduced. This was followed in 1913 by the first appearance of the famous circle and horizontal bar symbol, known as "the roundel", designed by Edward Johnston

On 1 January 1913 the UERL absorbed two other independent tube lines, the C&SLR and the Central London Railway. As the Combine expanded, only the Metropolitan stayed away from this process of integration, retaining its ambition to be considered as a main line railway. Proposals were put forward for a merger between the two companies in 1913 but the plan was rejected by the Metropolitan. In the same year the company asserted its independence by buying out the cash strapped Great Northern and City Railway. It also sought a character of its own. The Metropolitan Surplus Lands Committee had been formed in 1887 to develop accommodation alongside the railway and in 1919 Metropolitan Railway Country Estates Ltd. was founded to capitalise on the post-World War One demand for housing. This ensured that the Metropolitan would retain an independent image until the creation of London Transport in 1933.

The Metropolitan also sought to electrify its lines. The District and the Metropolitan had agreed to use the low voltage dc system for the Inner Circle, comprising two electric rails to power the trains, back in 1901. At the start of 1905 electric trains began to work the Uxbridge branch and from 1 November 1906 electric locomotives took trains as far as Wembley Park

This consisted of plans to extend some lines, to take over the operation of others from main-line railway companies, and to electrify the entire network.

The implementation of nationalised railways was a move of necessity as well as ideology. The main line railways had struggled to cope with a war economy in the First World War and by the end of World War Two the four remaining companies were on the verge of bankruptcy. Nationalisation was the easiest way to save the railways in the short term and provide money to fix war time damage.

They ruled that the Act stipulated that London Transport must plan, as far as was possible, to break even.

 was directly responsible. The Government planned to modernise the system while slashing its subsidy from taxpayers and ratepayers. As part of this strategy London Underground Limited was set up on 1 April 1985 as a wholly owned subsidiary of LRT to run the network.

The prognosis for LRT was good. Oliver Green, the then Curator of the London Transport Museum, wrote in 1987:

"In its first annual report, London Underground Ltd was able to announce that more passengers had used the system than ever before. In 1985-86 the Underground carried 762 million passengers - well above its previous record total of 720 million in 1948. At the same time costs have been significantly reduced with a new system of train overhaul and the introduction of more driver-only operation. Work is well in hand on the conversion of station booking offices to take the new Underground Ticketing System (UTS)...and prototype trials for the next generation of tube trains (1990) stock started in late 1986. As the London Underground celebrates its 125th anniversary in 1988, the future looks promising."


However cost-cutting was not without its critics. At 19:30 on 18 November 1987 a fire

), the fire was most probably caused by a commuter discarding a burning match, which fell down the side of the escalator onto the running track (Fennell 1988, p. 111). The running track had not been cleaned in some time and was covered in grease and fibrous detritus. The Member of Parliament

) under 30-year contracts, whilst London Underground Limited remained publicly owned and operated by TfL.

There was much controversy over the implementation of the PPP. Supporters of the change claimed that the private sector would eliminate the inefficiencies of public sector enterprises and take on the risks associated with running the network, while opponents said that the need to make profits would reduce the investment and public service aspects of the Underground.

The case for PPP was also weakened in 2008 when it was revealed that the demise of Metronet had cost the UK government £2 billion.

But under a deal struck with the government in 2003 the companies were protected from any further liability. The UK taxpayer therefore had to foot the rest of the bill. This undermined the argument that the PPP would place the risks involved in running the network into the hands of the private sector.

Transport for London

Transport for London (TfL) was created in 2000 as the integrated body responsible for London's transport system. It replaced London Regional Transport. It assumed control of London Underground Limited in July 2003.

TfL is part of the Greater London Authority
Greater London Authority

The Greater London Authority is the region-wide governing body for London, England. It consists of a directly-elected executive Mayor of London, currently Boris Johnson, and an elected 25-member London Assembly with scrutiny powers....
 and is constituted as a statutory corporation regulated under local government finance rules. It has three subsidiaries: London Transport Insurance (Guernsey) Ltd., the TfL Pension Fund Trustee Co. Ltd. and Transport Trading Ltd (TTL). TTL has six wholly-owned subsidiaries, one of which is London Underground Limited.

The TfL Board is appointed by the Mayor of London. The Mayor also sets the structure and level of public transport fares in London. However the day-to-day running of the corporation is left to the Commissioner

The Mayor is responsible for producing an integrated transport strategy for London and for consulting the GLA, TfL, local councils and others on the strategy. The Mayor is also responsible for setting TfL's budget. The GLA is consulted on the Mayor's transport strategy, and inspects and approves the Mayor's budget. It is able to summon the Mayor and senior staff to account for TfL's performance. London TravelWatch, a body appointed by and reporting to the Assembly, deals with complaints about transport in London.

London Underground Subsurface and Tube Trains
Lines on the Underground can be classified into two types: subsurface and deep-level. The subsurface lines were dug by the cut-and-cover method, with the tracks running about below the surface. The deep-level or tube lines, bored using a tunnelling shield

 is thus considerably smaller than on the subsurface lines. Lines of both types usually emerge onto the surface outside the central area.

While the tube lines are for the most part self-contained, the subsurface lines are part of an interconnected network: each shares track with at least two other lines. The subsurface arrangement is similar to the New York City Subway

The Underground is one of the few networks in the world that uses a four-rail system. The additional rail carries the electrical return that on third-rail and overhead networks is provided by the running rails. On the Underground a top-contact third rail is beside the track, energised at +420 V DC, and a top-contact fourth rail is centrally between the running rails, at -210 V DC, which combine to provide a traction voltage of 630 V DC.

As some part of the lines, that are used bei third rail system trains, too, work with third rail besides at +630 V (see http://trainblog.com/tags/subway-underground-metro/) (and the centrally fourth rail between the running rails at +/- 0 V, there cannot be a technical reason in at least a part of the trains.

, which is planned to begin operation in 2025, may be part of the London Underground, which would mean it would give the network a new Northeast to South cross London line to provide more interchanges with other lines and relieve overcrowding on other lines. However it is still on the drawing board. It was first proposed in 1901 and has been in planning since then. In 2007 the line was passed over to Cross London Rail Ltd, the current developers of Crossrail. Therefore, the line may be either part of the London Underground network or the National Rail network. There are advantages and disadvantages for both.

London Heathrow Airport

London Heathrow Airport or Heathrow , located in the London Borough of Hillingdon, is the largest and Busiest airports in the United Kingdom by total passenger traffic airport in the United Kingdom....
. Stations on the Metropolitan line outside Greater London are in Zones 7-9.

Travelcard zones 7–9 also apply on the Euston-Watford Junction line (part of the London Overground) as far as Watford High Street. Watford Junction is outside these zones and special fares apply.

There are staffed ticket offices, some open for limited periods only, and ticket machines usable at any time. Some machines that sell a limited range of tickets accept coins only, other touch-screen machines accept coins and banknotes, and usually give change. These machines also accept major credit and debit cards: some newer machines accept cards only.

More recently, TfL has introduced the Oyster card
Oyster card

The Oyster card is a form of electronic ticketing used on public transport services within the Greater London area of the United Kingdom. It is promoted by Transport for London and is valid on a number of different travel systems including London Underground, London buses, the Docklands Light Railway , London Overground, Tramlink and some Nat...
, a smartcard with an embedded contactless RFID chip, that travellers can obtain, charge with credit, and use to pay for travel. Like Travelcards they can be used on the Underground, buses, trams and the Docklands Light Railway. The Oyster card is cheaper to operate than cash ticketing or the older-style magnetic-strip-based Travelcards, and the Underground is encouraging passengers to use Oyster cards instead of Travelcards and cash (on buses) by implementing significant price differences. Oyster-based Travelcards can be used on National Rail throughout London. Pay as you go is available on a restricted, but increasing, number of routes
Oyster card (pay as you go) on National Rail

The acceptance of Oyster Card on National Rail in London, England has been limited to a restricted number of National Rail services since the introduction of the stored-value card product on London Underground in January 2004....
.

For tourists or other non-residents, not needing to travel in the morning peak period, the all day travelcard is the best ticketing option available. These are available from any underground station. These cost around £5.50 and allow unlimited travel on the network from 9:30am onwards for the rest of the day. This provides excellent value for money and a huge saving considering one single journey on the network can cost close to £5. Travel cards for multiple days are also available.

Penalty fares and fare evasion

Delays

According to statistics obtained under the Freedom of Information Act, the average commuter on the Metropolitan line wasted three days, 10 hours and 25 minutes in 2006 due to delays (not including missed connections). Between 17 September 2006 and 14 October 2006, figures show that 211 train services were delayed by more than 15 minutes. Passengers are entitled to a refund if their journey is delayed by 15 minutes or more due to circumstances within the control of TfL.

Hours of operation

The Underground does not run 24 hours a day (except at New Year and major public events - such as the Queen's Golden Jubilee in 2002 and the Opening and Closing Ceremonies of the London Olympics

TfL plans that by 2020 there should be a network of over 100 fully accessible stations, consists of those recently built or rebuilt, and a handful of suburban stations that happen to have level access, along with selected 'key stations', which will be rebuilt. These key stations have been chosen due to high usage, interchange potential, and geographic spread, so that up to 75% of journeys will be achievable step-free.

Overcrowding

Overcrowding on the Underground has been of concern for years and is very much the norm for most commuters especially during the morning and evening rush hours. Stations which particularly have a problem include Camden Town station

 may be present to help with overcrowding.

On 24 September 2007 the entirety of King's Cross underground station was closed due to "overcrowding". Some stations are closed or are made exit-only stations due to overcrowding in peak periods. At other times trains simply don't stop at the overcrowded station and go onto the next closest station, in places where there is another station within walking distance. Overcrowding can also be limited by temporarily disallowing passengers from passing through ticket gates to the platforms at some stations.

According to a 2003 House of Commons report, commuters faced a "daily trauma" and were forced to travel in "intolerable conditions".

TfL licences the sale of clothing and other accessories featuring its graphic elements and it takes legal action against unauthorised use of its trademarks and of the Tube map. Nevertheless, unauthorised copies of the logo continue to crop up worldwide.

Map


The original maps were often street maps with the lines superimposed, but as well as being visually complex, this produced problems of space, as central stations were far closer together than outlying ones.

The modern stylised Tube map evolved from a design by electrical engineer Harry Beck in 1933. It is characterized by a schematic non-geographical layout (thought to have been based on circuit diagram

s) and the use of colour coding for lines.

The map is now considered a design classic; virtually every major urban rail system in the world now has a similar map, and many bus companies have also adopted the concept.

There are many references in culture to the map, including parodies of it using different station-names, particularly in London advertisements for unrelated products & services.
