169-703: The Metropolitan line , colloquially known as the Met , is a London Underground line between Aldgate in the City of London and Amersham and Chesham in Buckinghamshire , with branches to Watford in Hertfordshire and Uxbridge in Hillingdon . Printed in magenta on the tube map , the line is 41.4 miles (66.7 km) in length and serves 34 stations (13 of which are step free to platform). Between Aldgate and Finchley Road ,
338-588: A Beadle , an ancient position which is now largely ceremonial whose main remaining function is the running of an annual Wardmote of electors, representatives and officials. At the Wardmote the ward's Alderman appoints at least one Deputy for the year ahead, and Wardmotes are also held during elections. Each ward also has a Ward Club, which is similar to a residents' association . The wards are ancient and their number has changed three times since time immemorial : Following boundary changes in 1994, and later reform of
507-484: A public–private partnership managed by the Metronet consortium. Metronet entered administration in 2007 and Transport for London took over responsibilities. On 12 December 2010, the service to Amersham was reduced from four trains per hour to two, and a direct service between Chesham and central London was introduced, replacing the 4-car Chesham to Chalfont & Latimer shuttle. The final passenger services operated by
676-456: A triangle junction with the main line, with a north-facing curve between Croxley and Rickmansworth . This route, Watford North Curve, is used daily for a few services and empty stock movements. From the Watford triangle to Amersham , the line has two tracks. At Chalfont & Latimer , the 3.89 miles (6.26 km) single-track Chesham branch diverges, running parallel to the main line for
845-509: A change of government at Westminster meant the option was not taken up. The city as a distinct polity survived despite its position within the London conurbation and numerous local government reforms . Supporting this status, the city was a special parliamentary borough that elected four members to the unreformed House of Commons , who were retained after the Reform Act 1832 ; reduced to two under
1014-499: A confrontation that included Lord Mayor William Walworth . In 1450, rebel forces again occupied the City during Jack Cade's Rebellion before being ousted by London citizens following a bloody battle on London Bridge. In 1550, the area south of London Bridge in Southwark came under the control of the City with the establishment of the ward of Bridge Without . The city was burnt severely on
1183-589: A day use District Line tracks between Wimbledon and East Putney. London Underground trains come in two sizes, larger sub-surface trains and smaller deep-tube trains. Since the early 1960s all passenger trains have been electric multiple units with sliding doors and a train last ran with a guard in 2000. All lines use fixed-length trains with between six and eight cars, except for the Waterloo & City line that uses four cars. New trains are designed for maximum number of standing passengers and for speed of access to
1352-451: A day. In 2023/24 it was used for 1.181billion passenger journeys. The system's first tunnels were built just below the ground, using the cut-and-cover method; later, smaller, roughly circular tunnels—which gave rise to its nickname, the Tube—were dug through at a deeper level. Despite its name, only 45% of the system is under the ground: much of the network in the outer environs of London
1521-761: A diameter of about 11 feet 8 inches (3.56 m), with one tube for each direction. The seven deep-level lines have the exclusive use of tracks and stations along their routes with the exceptions of the Piccadilly line, which shares track with the District line, between Acton Town and Hanger Lane Junction, and with the Metropolitan line, between Rayners Lane and Uxbridge; and the Bakerloo line, which shares track with London Overground 's Watford DC Line for its above-ground section north of Queen's Park. Fifty-five per cent of
1690-457: A distance. The Metropolitan line ends at Amersham, where there are turnback sidings just beyond the platforms. The route continues to Aylesbury with Chiltern Railways trains only. The fast (non-stopping) lines between Wembley Park and Harrow on the Hill are signalled with LUL signalling, but using four-aspect Network Rail signal heads. The upper two lights are a two-aspect stop signal displaying either
1859-489: A green or red aspect, the lower two lights a repeater signal for the next stop signal ahead showing a green or yellow aspect, or no aspect when the stop signal shows a red aspect. Thus they are effectively four-light three-aspect signals with green/red/green/yellow lights from the top, danger being a single red light, caution the top green light over a yellow light, and clear two green lights.

Historically its system of government was not unusual, but it was not reformed by the Municipal Corporations Act 1835 and little changed by later reforms, so that it is the only local government in the UK where elections are not run on the basis of one vote for every adult citizen. It
2197-538: A major commercial centre in Roman Britain until its abandonment during the 5th century . Archaeologist Leslie Wallace notes that, because extensive archaeological excavation has not revealed any signs of a significant pre-Roman presence, "arguments for a purely Roman foundation of London are now common and uncontroversial." At its height, the Roman city had a population of approximately 45,000–60,000 inhabitants. Londinium
2366-476: A major meeting point for businesses. London was ranked second (after New York) in the Global Financial Centres Index , published in 2022. The insurance industry is concentrated in the eastern side of the city, around Lloyd's building . Since about the 1980s, a secondary financial district has existed outside the city, at Canary Wharf, 2.5 miles (4 km) to the east. The legal profession has

Primarily a business district, the City has a small resident population of 8,583 based on 2021 census figures, but over 500,000 are employed there (as of 2019) and some estimates put
2704-468: A more modest scale than originally planned. Until 1961, passenger trains continued to be attached to a steam locomotive at Rickmansworth to run to Aylesbury. The rebuilding electrified the line from Rickmansworth to Amersham, transferring all Aylesbury services to British Railways. A pair of fast lines was added from Harrow to north of Moor Park by 1962, allowing outer-suburban trains to run fast to Moor Park. Aluminium A stock , originally unpainted, replaced
2873-614: A name of a street and an area of the City of Westminster between Westminster and the City of London. Following the Battle of Hastings , William the Conqueror marched on London, reaching as far as Southwark , but failed to get across London Bridge or defeat the Londoners. He eventually crossed the River Thames at Wallingford , pillaging the land as he went. Rather than continuing the war, Edgar
3042-491: A number of occasions, the worst being in 1123 and in the Great Fire of London in 1666. Both of these fires were referred to as the Great Fire. After the fire of 1666, a number of plans were drawn up to remodel the city and its street pattern into a renaissance -style city with planned urban blocks, squares and boulevards. These plans were almost entirely not taken up, and the medieval street pattern re-emerged almost intact. In
3211-511: A potential difference of 630 V . On the sections of line shared with mainline trains, such as the District line from East Putney to Wimbledon and Gunnersbury to Richmond, and the Bakerloo line north of Queen's Park, the centre rail is bonded to the running rails. The average speed on the Underground is 20.5 mph (33.0 km/h). Outside the tunnels of central London, many lines' trains tend to travel at over 40 mph (64 km/h) in
3380-579: A public transport system. The LPTB commissioned many new station buildings, posters and public artworks in a modernist style. The schematic Tube map , designed by Harry Beck in 1931, was voted a national design icon in 2006 and now includes other transport systems besides the Underground, such as the Docklands Light Railway , London Overground , Thameslink , the Elizabeth line , and Tramlink . Other famous London Underground branding includes

A second short branch line, known as the Halton Railway , served RAF Halton near Wendover, across the Wendover Arm of the Grand Union Canal. The line was built during the First World War and closed in 1963. The trackbed is now a footpath. London Underground The London Underground (also known simply as the Underground or by its nickname
3887-472: A self-governing unit within the wider city. They can be described as electoral/political divisions; ceremonial, geographic and administrative entities; sub-divisions of the city. Each ward has an Alderman , who until the mid-1960s held office for life but since put themselves up for re-election at least every 6 years, and are the only directly elected Aldermen in the United Kingdom . Wards continue to have
4056-430: A top speed of 62 miles per hour (100 km/h), being the only London Underground stock to travel at that speed, doing so on the long-distance sections north of Finchley Road. There are 58 S8 Stock trains in operation, as well as one eight-car S7 Stock also called 'S7+1' – which retains the all-longitudinal seating of the normal seven-car S7 Stock that is operated on London Underground's other sub-surface lines. The line
4225-460: A total frequency of 16 tph between Baker Street and Harrow-on-the-Hill. Of these, 12 tph run between Aldgate and Baker Street which, together with the 6 tph frequencies on both the Circle and Hammersmith & City lines, gives a total of 24 trains every hour on the central-London section between Liverpool Street and Baker Street. In the morning peak, the southbound service pattern
4394-399: A wholly owned subsidiary of Transport for London (TfL), the statutory corporation responsible for the transport network in London. As of 2015 , 92% of operational expenditure is covered by passenger fares. The Travelcard ticket was introduced in 1983 and Oyster card , a contactless ticketing system, in 2003. Contactless bank card payments were introduced in 2014, the first such use on

The Underground is served by the following depots: In the years since the first parts of the London Underground opened, many stations and routes have been closed. Some stations were closed because of low passenger numbers rendering them uneconomical; some became redundant after lines were re-routed or replacements were constructed; and others are no longer served by

It oversees the Barbican Centre and subsidises several important performing arts companies. The London Port Health Authority, which is the responsibility of the corporation, is responsible for all port health functions on
5577-453: Is not directly connected with the fast line at Moor Park. No Metropolitan line trains call at any intermediate stations between Finchley Road and Wembley Park. These stations are served by the Jubilee line which runs parallel to the Metropolitan line along this section. During the off-peak the service pattern on the line, in trains per hour (tph), is as follows: These services combine to give

The early tube lines, originally owned by several private companies, were brought together under the Underground brand in the early 20th century, and eventually merged along with the sub-surface lines and bus services in 1933 to form London Transport under the control of the London Passenger Transport Board (LPTB). The current operator, London Underground Limited (LUL), is
6084-599: Is served by a depot at Neasden. The Metropolitan Railway opened a carriage works at Neasden in 1882 and the following year the locomotive works were moved from Edgware Road. In 1904–05, the depot was refitted to take the new electric multiple units and accommodation enlarged in 1932–3. After the amalgamation into the LTPB, the depot was rebuilt from 1936 to 1939. The depot was upgraded in 2010–11 to enable it to maintain S Stock trains. Trains are also stored overnight at Uxbridge, Watford, Rickmansworth and Wembley Park. In 1989, to celebrate

Similarly, in the evening peak, the northbound service pattern is strengthened to the following: The southbound frequencies in the evening peak are similar on each route, except all trains run as all-stations services. Since 20 September 2012, all services have been provided by eight-car S Stock trains introduced in July 2010 to replace
6422-426: Is the southbound terminus for some trains not continuing to Aldgate. Most of the route has two tracks, except for the single-track Chesham branch and a four-track section between Wembley Park and Moor Park that allows fast and semi-fast services to overtake "all stations" trains. There are four tracks between Wembley Park and Finchley Road, but only the outer ones are used by the Metropolitan line's non-stop trains:
6591-683: Is unique in the United Kingdom as it is not conducted by the Electoral Commission or a local government boundary commission every 8 to 12 years, which is the case for all other wards in Great Britain . Particular churches, livery company halls and other historic buildings and structures are associated with a ward, such as St Paul's Cathedral with Castle Baynard , and London Bridge with Bridge; boundary changes in 2003 removed some of these historic connections. Each ward elects an alderman to

7098-803: The Carausian Revolt in Britain. In the 3rd and 4th centuries, the city was under attack from Picts , Scots, and Saxon raiders. The decline continued, both for Londinium and the Empire, and in AD 410 the Romans withdrew entirely from Britain. Many of the Roman public buildings in Londinium by this time had fallen into decay and disuse, and gradually after the formal withdrawal the city became almost (if not, at times, entirely) uninhabited. The centre of trade and population moved away from

The world's first underground railway, it opened on 10 January 1863 with gas-lit wooden carriages hauled by steam locomotives. The line operated at a frequency of three trains per hour, rising to four trains per hour during
12506-497: The City, namely the City of London Corporation , is unique in the UK and has some unusual responsibilities for a local council, such as being the police authority. It is also unusual in having responsibilities and ownerships beyond its boundaries, e.g. Hampstead Heath . The corporation is headed by the Lord Mayor of the City of London (an office separate from, and much older than, the Mayor of London ). The Lord Mayor, as of November 2023,
12675-744: The District Railway and established the Underground Electric Railways Company of London (UERL) in 1902 to finance and operate three tube lines, the Baker Street and Waterloo Railway (Bakerloo), the Charing Cross, Euston and Hampstead Railway (Hampstead) and the Great Northern, Piccadilly and Brompton Railway , (Piccadilly), which all opened between 1906 and 1907. When the "Bakerloo" was so named in July 1906, The Railway Magazine called it an undignified "gutter title". By 1907
12844-668: The District and Metropolitan Railways had electrified the underground sections of their lines. In January 1913, the UERL acquired the Central London Railway and the City & South London Railway , as well as many of London's bus and tram operators. Only the Metropolitan Railway , along with its subsidiaries the Great Northern & City Railway and the East London Railway , and the Waterloo & City Railway , by then owned by
13013-454: The Jubilee carriage, including a Steam back on the Met scheduled for May. It was planned that a new signalling system would be used first on the line north of Baker Street from the end of 2016, but signalling contractor Bombardier was released from its contract by agreement in December 2013 amid heavy criticism of the procurement process and London Underground subsequently awarded the contract for
13182-549: The Jubilee line diverges to the Stanmore branch at a grade-separated junction. From just after Finchley Road, these four tracks run parallel with the Network Rail Chiltern Main Line from Marylebone . Between Wembley Park and Harrow-on-the-Hill , the Metropolitan is four-track, with fast and slow lines paired by direction, paralleling the two-track un-electrified London–Aylesbury line . The slow lines are between
13351-415: The Jubilee line serving the intermediate stations on an adjacent parallel line. The Jubilee line then joins the Metropolitan line in the same right-of-way at Finchley Road. Metropolitan line trains then run express from Finchley Road to Wembley Park , with the Jubilee line serving the intermediate stations. Metropolitan line platforms at Willesden Green and Neasden remain for emergency use. At Wembley Park
13520-587: The London Underground. In 1976, the Northern City Line was taken over by British Rail and linked up with the main line railway at Finsbury Park , a transfer that had already been planned prior to the accident. In 1979, another new tube, the Jubilee line , named in honour of the Silver Jubilee of Elizabeth II , took over the Stanmore branch from the Bakerloo line, linking it to a newly constructed line between Baker Street and Charing Cross stations. Under
13689-403: The Metropolitan line station . The Bakerloo line service to Stanmore was transferred to the Jubilee line when that line opened in 1979. In 1961, when steam locomotives were replaced and the line was electrified to Amersham, the Underground service to Great Missenden , Wendover , Stoke Mandeville and Aylesbury was withdrawn. Between Moor Park and Croxley, a short branch ran south-east off
13858-401: The Metropolitan line with a white line in the middle, changed to orange by the 1990 map. In 1990, the Hammersmith & City line became a separate line from Hammersmith to Whitechapel (Barking during the peak), the Metropolitan line being from Aldgate to Baker Street and northwards to Amersham with branches to Chesham, Uxbridge and Watford. In 2003, the infrastructure was partly privatised in
14027-503: The Metropolitan was amalgamated with other Underground railways, tramway companies and bus operators to form the London Passenger Transport Board , and a period of rationalisation followed. While the Metropolitan was run as an outer suburban route with steam-hauled trains and goods services, the LPTB wished to focus on electrified trains and suburban traffic. Goods services were passed to the London and North Eastern Railway , which also took over
14196-517: The Piccadilly line) just inside its boundaries. Lewisham was served by the East London line (with stations at New Cross and New Cross Gate ) until 2010 when the line and the stations were transferred to the London Overground network. London Underground's eleven lines total 402 kilometres (250 mi) in length, making it the eleventh longest metro system in the world . These are made up of
14365-450: The Roman evacuation and abandonment of Londinium, was rebuilt by the Saxons, but was periodically destroyed by Viking raids and storms. As the focus of trade and population was moved back to within the old Roman walls, the older Saxon settlement of Lundenwic was largely abandoned and gained the name of Ealdwic (the "old settlement"). The name survives today as Aldwych (the "old market-place"),
14534-570: The Royal Exchange. Immediately to the south of Cornhill, Lombard Street was the location from 1691 of Lloyd's Coffee House , which became the world-leading insurance market. London's insurance sector continues to be based in the area, particularly in Lime Street . In 1708, Christopher Wren 's masterpiece, St Paul's Cathedral , was completed on his birthday. The first service had been held on 2 December 1697, more than 10 years earlier. It replaced
14703-529: The T stock and locomotive-hauled trains. More A Stock trains were built in 1962–63 to replace the trains on the Uxbridge service, giving the main line a single train type for all services. A Stock was four-car units that could operate as four- or eight-car trains; normally operated as eight cars, a four-car unit operated the Chesham shuttle. One person operation of the trains was proposed in 1972, but due to conflict with
14872-493: The Tube ) is a rapid transit system serving Greater London and some parts of the adjacent home counties of Buckinghamshire , Essex and Hertfordshire in England. The Underground has its origins in the Metropolitan Railway , opening on 10 January 1863 as the world's first underground passenger railway. The Metropolitan is now part of the Circle , District , Hammersmith & City and Metropolitan lines . The first line to operate underground electric traction trains ,
15041-451: The Tube has taken place - with new trains (such as London Underground S7 and S8 Stock ), new signalling, upgraded stations (such as King's Cross St Pancras ) and improved accessibility (such as at Green Park ). Small changes to the Tube network occurred in the 2000s, with extensions to Heathrow Terminal 5 , new station at Wood Lane and the Circle line changed from serving a closed loop around
15210-436: The Underground but remain open to National Rail main line services. In some cases, such as Aldwych and Ongar , the buildings remain and are used for other purposes. In others, such as British Museum , all evidence of the station has been lost through demolition. London Transport Museum runs guided tours of several disused stations including Down Street and Aldwych through its "Hidden London" programme. The tours look at
15379-510: The Uxbridge branch were rebuilt, replacing temporary wooden buildings with modernist designs and giving Uxbridge station a new site in the town centre. A major bottleneck in the line, the double-track tunnel from Baker Street to Finchley Road, was bypassed by boring two tube tunnels underneath the Metropolitan tunnels, transferring slow services and the Stanmore branch to the Bakerloo line . (This route
15548-546: The Viking occupation and raids. While London, and indeed England, were afterwards subjected to further periods of Viking and Danish raids and occupation, the establishment of the City of London and the Kingdom of England prevailed. In the 10th century, Athelstan permitted eight mints to be established, compared with six in his capital, Winchester , indicating the wealth of the city. London Bridge, which had fallen into ruin following
15717-477: The Watford branch, near its junction with the main line, to Croxley Tip, a rubbish dump beside the Grand Union Canal. This site began as a gravel loading point before becoming used by the railway to dump waste such as old ballast and waste from Neasden power station . This route, never used for passenger traffic, continued to be used by London Transport's small fleet of steam engines until 1971, when diesels replaced them. The branch closed some time after this, although
15886-599: The advent of electric Tube services (the Waterloo and City Railway and the Great Northern and City Railway), the Volks Electric Railway , in Brighton , and competition from electric trams, the pioneering Underground companies needed modernising. In the early 20th century, the District and Metropolitan railways needed to electrify and a joint committee recommended an AC system, the two companies co-operating because of
16055-483: The air through the installation of garden plants. The Metropolitan even encouraged beards for staff to act as an air filter. There were other reports claiming beneficial outcomes of using the Underground, including the designation of Great Portland Street as a " sanatorium for [sufferers of ...] asthma and bronchial complaints", tonsillitis could be cured with acid gas and the Twopenny Tube cured anorexia . With
16224-612: The borders of the City of London, most notably during this period towards the West End and Westminster. Expansion continued and became more rapid by the beginning of the 19th century, with London growing in all directions. To the East the Port of London grew rapidly during the century, with the construction of many docks, needed as the Thames at the City could not cope with the volume of trade. The arrival of
16393-459: The business vote in the city, there was a major boundary and electoral representation revision of the wards in 2003, and they were reviewed again in 2010 for change in 2013, though not to such a dramatic extent. The review was conducted by senior officers of the corporation and senior judges of the Old Bailey ; the wards are reviewed by this process to avoid malapportionment . The procedure of review
16562-432: The cars and have regenerative braking and public address systems. Since 1999 all new stock has had to comply with accessibility regulations that require such things as access and room for wheelchairs, and the size and location of door controls. All underground trains are required to comply with The Rail Vehicle Accessibility (Non Interoperable Rail System) Regulations 2010 (RVAR 2010) by 2020. Stock on sub-surface lines
16731-605: The centre of London to a spiral also serving Hammersmith in 2009. In July 2005, four coordinated terrorist attacks took place, three of them occurring on the Tube network. It was the UK's deadliest terrorist incident since 1988. Electronic ticketing in the form of the contactless Oyster card was first introduced in 2003, with payment using contactless banks cards introduced in September 2014. In 2019 , over 12million Oyster cards and 35million contactless cards were used, generating around £5billion in ticketing revenue. During
16900-656: The city as a central business district led to this falling to below 5,000 after the Second World War. It has risen slightly to around 9,000 since, largely due to the development of the Barbican Estate . In 2009, the business vote was about 24,000, greatly exceeding residential voters. As the City of London Corporation has not been affected by other municipal legislation over the period of time since then, its electoral practice has become increasingly anomalous. Uniquely for city or borough elections, its elections remain independent-dominated. The business or " non-residential vote "
17069-573: The construction of tall office buildings including the 600-foot (183 m), 47-storey NatWest Tower , the first skyscraper in the UK. By the 2010s, office space development had intensified in the City, especially in the central, northern and eastern parts, with skyscrapers including 30 St. Mary Axe ("the Gherkin"'), Leadenhall Building ("the Cheesegrater"), 20 Fenchurch Street ("the Walkie-Talkie"),
17238-551: The control of the GLC, London Transport introduced a system of fare zones for buses and underground trains that cut the average fare in 1981. Fares increased following a legal challenge but the fare zones were retained, and in the mid-1980s the Travelcard and the Capitalcard were introduced. In 1984, control of London Buses and the London Underground passed back to central government with
17407-520: The creation of London Regional Transport (LRT), which reported directly to the Secretary of State for Transport , still retaining the London Transport brand. One person operation had been planned in 1968, but conflict with the trade unions delayed introduction until the 1980s. On 18 November 1987, fire broke out in an escalator at King's Cross St Pancras tube station . The resulting fire cost
17576-534: The development of new suburbs. Harrow was reached in 1880, and ultimately, as far as Verney Junction in Buckinghamshire , more than 50 miles (80 kilometres) from Baker Street. From the end of the 19th century, the railway shared tracks with the Great Central Railway route out of Marylebone . Electric traction was introduced in 1905 with electric multiple units operating between Uxbridge, Harrow-on-the-Hill and Baker Street. To remove steam and smoke from
17745-653: The early 1960s, the Metropolitan line was electrified as far as Amersham , British Railways providing services for the former Metropolitan line stations between Amersham and Aylesbury. In 1962, the British Transport Commission was abolished, and the London Transport Executive was renamed the London Transport Board , reporting directly to the Minister of Transport . Also during the 1960s,
17914-463: The early 2000s, London Underground was reorganised in a Public-Private Partnership (PPP) as part of a project to upgrade and modernise the system. Private infrastructure companies (infracos) would upgrade and maintain the railway, and London Underground would run the train service. One infraco – Metronet – went into administration in 2007, and TfL took over the other – Tube Lines – in 2010. Despite this, substantial investment to upgrade and modernise
18083-682: The emergency services. In April 1994, the Waterloo & City Railway , by then owned by British Rail and known as the Waterloo & City line, was transferred to the London Underground. In 1999, the Jubilee Line Extension project extended the Jubilee line from Green Park station through the growing Docklands to Stratford station . This resulted in the closure of the short section of tunnel between Green Park and Charing Cross stations. The 11 new stations were designed to be " future-proof ", with wide passageways, large quantities of escalators and lifts, and emergency exits. The stations were
18252-520: The end of May. From 1994, diesel locomotive 20227, owned by the Class 20 Locomotive Society, and electric locomotive Sarah Siddons provided air braking for the coaches. In 1995, trains ran between Amersham and Watford. Engines used included BR standard class 5 and BR standard class 4 and GWR Pannier tanks . There was other rolling stock on static display at Rickmansworth sidings. The steam trains ran between normal Metropolitan and main line services. Due to
18421-461: The fast lines, and the two intermediate stations have island platforms. Harrow-on-the-Hill has platforms on all six lines. The central slow lines diverge here at a grade-separated junction to become the 7.5 miles (12.1 km) Uxbridge branch. After West Harrow , at Rayners Lane the line is joined by the Piccadilly line , which shares the tracks to Uxbridge; a turnback siding allows some Piccadilly line services to terminate at Rayners Lane. On
18590-590: The first bishop to the Anglo-Saxon kingdom of the East Saxons and their king, Sæberht . Sæberht's uncle and overlord, Æthelberht , king of Kent , built a church dedicated to St Paul in London, as the seat of the new bishop. It is assumed, although unproven, that this first Anglo-Saxon cathedral stood on the same site as the later medieval and the present cathedrals. Alfred the Great , King of Wessex occupied and began
18759-549: The first on the Underground to have platform edge doors , and were built to have step-free access throughout. The stations have subsequently been praised as exemplary pieces of 20th-century architecture. In 2000, Transport for London (TfL) was created as an integrated body responsible for London's transport system. Part of the Greater London Authority , the TfL Board is appointed by the Mayor of London , who also sets
18928-606: The form of the Greater London Council (GLC), and the London Transport Board was abolished. The London Transport brand continued to be used by the GLC. On 28 February 1975, a southbound train on the Northern City Line failed to stop at its Moorgate terminus and crashed into the wall at the end of the tunnel, in the Moorgate tube crash . There were 43 deaths and 74 injuries, the greatest loss of life during peacetime on
19097-532: The former East London line becoming part of the Overground network in 2010. Many Overground stations interchange with Underground ones, and Overground lines were added onto the Tube map. In the 2010s, the £18.8 billion Crossrail project built a new east–west railway tunnel under central London. The project involved rebuilding and expanding several central Underground stations including Tottenham Court Road and Whitechapel . By increasing rail capacity,
19266-609: The former Metropolitan Railway closed, the Brill Tramway in 1935, and the line from Quainton Road to Verney Junction in 1936. The 1935–40 New Works Programme included the extension of the Central and Northern lines and the Bakerloo line to take over the Metropolitan's Stanmore branch. The Second World War suspended these plans after the Bakerloo line had reached Stanmore and the Northern line High Barnet and Mill Hill East in 1941. Following bombing in 1940, passenger services over
19435-399: The history of the network and feature historical details drawn from the museum's own archives and collections. City of London The City of London , also known as the City , is a city , ceremonial county and local government district that contains the ancient centre, and constitutes, along with Canary Wharf , the primary central business district (CBD) of London and one of
19604-707: The imminent partial privatisation of LUL and the stock condition, the last steam excursion took place in 2000. In 2008, special trains ran on using Metropolitan Railway electric locomotive "Sarah Siddons" and diesel Class 20 locomotives. To celebrate the 150th anniversary of the opening of the Metropolitan, special services ran in January 2013 using a restored 1892 "Jubilee" carriage, 1898–1900 Ashbury and Cravens bogie carriages, Metropolitan Railway milk van No.3, Metropolitan Railway E Class steam locomotive No. 1 and electric locomotive Sarah Siddons . Further events were planned for 2013 involving Locomotive No. 1, Sarah Siddons and
19773-513: The inner pair was transferred to the Bakerloo line in 1939 (becoming the Jubilee line in 1979) with services calling at all stations. The Metropolitan Railway, also known as the Met , was a passenger and goods railway that served London from 1863 to 1933, its main line heading north-west from the City to what were to become the Middlesex suburbs. Its first line connected the mainline railway termini at Paddington , Euston and King's Cross to
19942-409: The inter-operability with Chiltern Railways which shares tracks with the Metropolitan line in this area. In order from east to west. The Brill Tramway with stations Waddesdon Road , Westcott , Wotton , Church Siding , Wood Siding and Brill closed in 1935. In the following year, the line was cut back to Aylesbury, with Waddesdon station and Granborough Road , Winslow Road stations on
20111-455: The leading financial centres of the world. It constituted most of London from its settlement by the Romans in the 1st century AD to the Middle Ages , but the modern area referred to as London has since grown far beyond the City of London boundary. The City is now only a small part of the metropolis of Greater London , though it remains a notable part of central London . The City of London
20280-516: The line aims to reduce overcrowding on the Tube and cut cross-London journey times. The railway opened as the Elizabeth line in May 2022. Although not part of the Underground, the line connects with several Underground stations. In 2020, passenger numbers fell significantly during the COVID-19 pandemic and 40 stations were temporarily closed. The Northern Line Extension opened in September 2021, extending
20449-593: The line north-west into the Middlesex countryside, where it stimulated the development of new suburbs. Harrow was reached in 1880, and ultimately the line continued as far as Verney Junction in Buckinghamshire, more than 50 miles (80 km) from Baker Street . From the end of the 19th century, the railway shared tracks with the Great Central Railway out of Marylebone . The central London lines were electrified by 1907 but electric locomotives were exchanged for steam locomotives on trains heading north of Harrow. After
20618-518: The line to Verney Junction closing. Initially Verney Junction and Quainton Road remained open, with main line services provided by the LNER. In 1939, the Stanmore branch and the stopping service between Finchley Road and Wembley Park were transferred to the Bakerloo line . On the St John's Wood section, Lord's and Marlborough Road stations were replaced by St John's Wood , and Swiss Cottage replaced
20787-411: The line. Electrification was extended north from Harrow to Rickmansworth , and branches opened from Rickmansworth to Watford in 1925 and from Wembley Park to Stanmore in 1932. The Piccadilly line was extended north to Cockfosters and took over District line branches to Harrow (later Uxbridge) and Hounslow. In 1933, most of London's underground railways, tramway and bus services were merged to form
20956-530: The lives of 31 people and injured a further 100. London Underground was strongly criticised in the aftermath for its attitude to fires underground, and publication of the report into the fire led to the resignation of senior management of both London Underground and London Regional Transport. Following the fire, substantial improvements to safety on the Tube were implemented – including the banning of smoking, removal of wooden escalators, installation of CCTV and fire detectors, as well as comprehensive radio coverage for
21125-618: The main line London and South Western Railway , remained outside the Underground Group's control. A joint marketing agreement between most of the companies in the early years of the 20th century included maps, joint publicity, through ticketing and U NDERGROUN D signs, incorporating the first bullseye symbol, outside stations in Central London. At the time, the term Underground was selected from three other proposed names; 'Tube' and 'Electric' were both officially rejected. Ironically,
21294-406: The main line between Harrow-on-the-Hill and Moor Park , the line is four-track, paired by use. The western fast tracks are shared with Aylesbury line services from Marylebone; the eastern slow tracks have platforms at the intermediate stations. North of Moor Park, the Watford branch diverges from the slow lines. This double-track branch has stations at Croxley and Watford . The Watford branch has
21463-480: The monarch. London's chosen sheriffs also served as the sheriffs for the county of Middlesex . This meant that the City and Middlesex were regarded as one administratively for addressing crime and keeping the peace (not that the county was a dependency of the city). London's sheriffs continued to serve Middlesex until the county was given its own sheriffs again following the Local Government Act 1888 . By 1141
21632-415: The nearly deserted Roman walled city, building quays along the Thames, and laying a new city street plan. Alfred's taking of London and the rebuilding of the old Roman city was a turning point in history, not only as the permanent establishment of the City of London, but also as part of a unifying moment in early England, with Wessex becoming the dominant English kingdom and the repelling (to some degree) of
21801-522: The neighbouring London Borough of Tower Hamlets . It owns and helps fund the Old Bailey , the Central Criminal Court for England and Wales , as a gift to the nation, having begun as the City and Middlesex Sessions. The Honourable The Irish Society , a body closely linked with the corporation, also owns many public spaces in Northern Ireland . The city has its own independent police force,
21970-409: The number of workers in the City to be over 1 million. About three-quarters of the jobs in the City of London are in the financial, professional, and associated business services sectors. The Roman legions established a settlement known as "Londinium" on the current site of the City of London around AD 43. Its bridge over the River Thames turned the city into a road nexus and major port , serving as
22139-441: The only London Underground line to operate non-stop services through some of its stations, although since 11 December 2011 these only run on weekdays during peak times (southbound in the morning peak, northbound in the evening peak). Since 8 April 2024, all trains in the northbound direction going towards Amersham and Chesham now run semi-fast and only run as an all-stations service in the first and last 4 hours of service. Depending on
22308-569: The original St Paul's, which had been completely destroyed in the Great Fire of London, and is considered to be one of the finest cathedrals in Britain and a fine example of Baroque architecture . The 18th century was a period of rapid growth for London, reflecting an increasing national population, the early stirrings of the Industrial Revolution , and London's role at the centre of the evolving British Empire . The urban area expanded beyond
22477-628: The peak periods. In the 1871 plans for an underground railway in Paris, it was called the Métropolitain . The railway was soon extended from both ends and northwards via a branch from Baker Street . It reached Hammersmith in 1864 and Richmond in 1877; it completed the Inner Circle in 1884, but the most important route became the line west and north-west into the Middlesex countryside, where it stimulated
22646-415: The post-war modernist changes made, such as at Paternoster Square . The City suffered terrorist attacks including the 1993 Bishopsgate bombing ( IRA ) and the 7 July 2005 London bombings ( Islamist ). In response to the 1993 bombing, a system of road barriers, checkpoints and surveillance cameras referred to as the " ring of steel " has been maintained to control entry points to the city. The 1970s saw
22815-526: The project to Thales in August 2015. With the introduction of S8 Stock, the track, electrical supply, and signalling systems are being upgraded in a programme planned to increase peak-hour capacity on the line by 27 per cent by the end of 2023. A single control room for the sub-surface railway opened at Hammersmith on 6 May 2018, and communications-based train control (CBTC) provided by Thales will progressively replace 'fixed block' signalling equipment dating back
22984-439: The railway was absorbed by the London Passenger Transport Board in 1933, the line was cut back to Aylesbury . Steam trains ran until 1961, when the line was electrified to and services were curtailed at Amersham. The Hammersmith & City line was shown on the tube map as a part of the Metropolitan line until 1990, when it appeared as a separate line. The current S8 Stock trains entered service between 2010 and 2012, replacing
23153-592: The railways and the Tube meant that London could expand over a much greater area. By the mid-19th century, with London still rapidly expanding in population and area, the City had already become only a small part of the wider metropolis. An attempt was made in 1894 with the Royal Commission on the Amalgamation of the City and County of London to end the distinction between the city and the surrounding County of London, but
23322-545: The resettlement of the old Roman walled area, in 886, and appointed his son-in-law Earl Æthelred of Mercia over it as part of their reconquest of the Viking occupied parts of England. The refortified Anglo-Saxon settlement was known as Lundenburh ("London Fort", a borough ). The historian Asser said that "Alfred, king of the Anglo-Saxons, restored the city of London splendidly ... and made it habitable once more." Alfred's "restoration" entailed reoccupying and refurbishing
23491-576: The retention of the business vote argue that it is a cause of institutional inertia. The City of London (Ward Elections) Act 2002 , a private Act of Parliament, reformed the voting system and greatly increased the business franchise, allowing many more businesses to be represented. Under the new system, the number of non-resident voters has doubled from 16,000 to 32,000. Previously disenfranchised firms (and other organisations) are entitled to nominate voters, in addition to those already represented, and all such bodies are now required to choose their voters in
23660-508: The roads to avoid the need for agreement with owners of property on the surface. This opened in 1890 with electric locomotives that hauled carriages with small opaque windows, nicknamed padded cells . The Waterloo and City Railway opened in 1898, followed by the Central London Railway in 1900, known as the "twopenny tube". These two ran electric trains in circular tunnels having diameters between 11 feet 8 inches (3.56 m) and 12 feet 2.5 inches (3.72 m), whereas
23829-423: The role of providing steam locomotives for trains beyond the end of electrification at Rickmansworth. All services north-west of Aylesbury were withdrawn by 1936 though services returned to Quainton Road between 1943 and 1948. The 1930s was a period of rapid growth for the north-western suburbs of London, and LPTB developed ambitious plans to simplify the Metropolitan line and expand capacity. Several stations on
23998-488: The service. The Metropolitan District Railway (commonly known as the District Railway ) opened in December 1868 from South Kensington to Westminster as part of a plan for an underground "inner circle" connecting London's main-line stations. The Metropolitan and District railways completed the Circle line in 1884, built using the cut and cover method. Both railways expanded, the District building five branches to
24167-579: The shared ownership of the inner circle. The District, needing to raise the finance necessary, found an investor in the American Charles Yerkes who favoured a DC system similar to that in use on the City & South London and Central London railways. The Metropolitan Railway protested about the change of plan, but after arbitration by the Board of Trade , the DC system was adopted. Yerkes soon had control of
24336-463: The stopping pattern, services are advertised as either all-stations , semi-fast or fast on platform information boards and on-train announcements. The stopping pattern of each type of service is as follows: Owing to the track layout, fast services can only run to/from Amersham or Chesham . The Uxbridge branch diverges from the rest of the line before the "fast" section, while the Watford branch
24505-540: The structure and level of public transport fares in London. The day-to-day running of the corporation is left to the Commissioner of Transport for London . TfL eventually replaced London Regional Transport, and discontinued the use of the London Transport brand in favour of its own brand. The transfer of responsibility was staged, with transfer of control of London Underground delayed until July 2003, when London Underground Limited became an indirect subsidiary of TfL. In
24674-612: The sub-surface network and the deep-tube lines. The Circle , District , Hammersmith & City , and Metropolitan lines form the sub-surface network, with cut-and-cover railway tunnels just below the surface and of a similar size to those on British main lines They converged on a bi-directional loop in central London, sharing tracks and stations with each other at various places along their respective routes. The Bakerloo , Central , Jubilee, Northern, Piccadilly, Victoria and Waterloo & City lines are deep-level tubes, with smaller trains that run in circular tunnels ( tubes ) with
24843-513: The suburban and countryside areas. The Metropolitan line can reach speeds of 62 mph (100 km/h). The London Underground was used for 1.181 billion journeys in the year 2023–2024. The Underground uses several railways and alignments that were built by main-line railway companies. Chiltern Railways shares track with the Metropolitan Line between Harrow-on-the-Hill and Amersham. Three South Western Railway passenger trains
25012-418: The system runs on the surface. There are 20 miles (32 km) of sub-surface tunnels and 93 miles (150 km) of tube tunnels. Many of the central London Underground stations on deep-level tube routes are higher than the running lines to assist deceleration when arriving and acceleration when departing. Trains generally run on the left-hand track. In some places, the tunnels are above each other (for example,
25181-457: The term Tube was later adopted alongside the Underground. The Bakerloo line was extended north to Queen's Park to join a new electric line from Euston to Watford , but the First World War delayed construction and trains reached Watford Junction in 1917. During air raids in 1915 people used the tube stations as shelters. An extension of the Central line west to Ealing was also delayed by
25350-450: The terms the City and the Square Mile are often used as metonyms for the UK's trading and financial services industries, which continue a notable history of being largely based in the City. The name London is now ordinarily used for a far wider area than just the City. London most often denotes the sprawling London metropolis, or the 32 Greater London boroughs, in addition to the City of London itself. The local authority for
25519-458: The track is mostly in shallow " cut and cover " tunnels, apart from short sections at Barbican and Farringdon stations. The rest of the line is above ground, with a loading gauge of a similar size to those on main lines. Just under 94 million passenger journeys were made on the line in 2019. The line is one of just two Underground lines to cross the Greater London boundary (the other being
25688-402: The trade unions was not introduced on the line until 1986. Although the East London line had been an isolated shuttle since 1939, it was shown on London Underground maps as part of the Metropolitan line until 1968. In 1970, it was shown with a thin white line in the middle and labelled the "East London section". By the 1985 map, it had become the "East London Line", remaining the same colour as
25857-410: The tunnels in central London, the railway purchased electric locomotives , exchanged for steam locomotives at Harrow from 1908. In 1910, a seventeen-minute silent film was made showing large portions of the journey from Baker Street to Aylesbury and Uxbridge, seen from the cab of a train. Unlike other railways in the London area, the Met developed land for housing, thus benefitting from the increase in
26026-428: The value of its land caused by the building of the railway. After World War I it promoted its housing estates near the railway with the " Metro-land " brand. To improve services, more powerful electric and steam locomotives were purchased in the 1920s. A short branch opened from Rickmansworth to Watford in 1925. After World War I , the 4-mile (6.4 km) Stanmore branch was built from Wembley Park. On 1 July 1933,
26195-632: The walled Londinium to Lundenwic ("London market"), a settlement to the west, roughly in the modern-day Strand / Aldwych / Covent Garden area. During the Anglo-Saxon Heptarchy , the London area came in turn under the Kingdoms of Essex , Mercia , and later Wessex , though from the mid 8th century it was frequently under threat from raids by different groups including the Vikings . Bede records that in AD 604 St Augustine consecrated Mellitus as
26364-437: The war and was completed in 1920. After the war, government-backed financial guarantees were used to expand the network and the tunnels of the City and South London and Hampstead railways were linked at Euston and Kennington; the combined service was not named the Northern line until later. The Metropolitan promoted housing estates near the railway with the " Metro-land " brand and nine housing estates were built near stations on
26533-498: The west reaching Ealing , Hounslow , Uxbridge , Richmond and Wimbledon and the Metropolitan eventually extended as far as Verney Junction in Buckinghamshire – more than 50 miles (80 km) from Baker Street and the centre of London. For the first deep-level tube line, the City and South London Railway , two 10 feet 2 inches (3.10 m) diameter circular tunnels were dug between King William Street (close to today's Monument station ) and Stockwell , under
26702-431: The western ward of Farringdon Without are within the boundaries and liberties of the City, but can be thought of as independent enclaves . They are two of the few remaining liberties , an old name for a geographic division with special rights. They are extra-parochial areas , historically not governed by the City of London Corporation (and are today regarded as local authorities for most purposes ) and equally outside
26871-465: The whole body of the citizenry was considered to constitute a single community. This ' commune ' was the origin of the City of London Corporation and the citizens gained the right to appoint, with the king's consent, a mayor in 1189—and to directly elect the mayor from 1215. From medieval times, the city has been composed of 25 ancient wards , each headed by an alderman , who chairs Wardmotes , which still take place at least annually. A Folkmoot , for
27040-409: The whole of the City held at the outdoor cross of St Paul's Cathedral , was formerly also held. Many of the medieval offices and traditions continue to the present day, demonstrating the unique nature of the City and its Corporation . In 1381, the Peasants' Revolt affected London. The rebels took the City and the Tower of London, but the rebellion ended after its leader, Wat Tyler, was killed during
27209-416: The worst civilian disaster in Britain during the Second World War, and the largest loss of life in a single incident on the London Underground network. On 1 January 1948, under the provisions of the Transport Act 1947 , the London Passenger Transport Board was nationalised and renamed the London Transport Executive , becoming a subsidiary transport organisation of the British Transport Commission , which
27378-461: The Ætheling , Edwin of Mercia and Morcar of Northumbria surrendered at Berkhamsted . William granted the citizens of London a charter in 1075; the city was one of a few examples of the English retaining some authority. The city was not covered by the Domesday Book . William built three castles around the city, to keep Londoners subdued: Around 1132 the City was given the right to appoint its own sheriffs rather than having sheriffs appointed by
27547-501: Was abolished in other UK local council elections by the Representation of the People Act 1969 , but was preserved in the City of London. The principal reason given by successive UK governments for retaining this mechanism for giving businesses representation, is that the city is "primarily a place for doing business". About 330,000 non-residents constitute the day-time population and use most of its services, far outnumbering residents, who number around 7,000 (2011). By contrast, opponents of
27716-399: Was an ethnically diverse city, with inhabitants from across the Roman Empire, including natives of Britannia, continental Europe , the Middle East, and North Africa. The Romans built the London Wall some time between AD 190 and 225. The boundaries of the Roman city were similar to those of the City of London today, though the City extends further west than Londinium's Ludgate , and the Thames
27885-430: Was formed on the same day. Under the same act, the country's main line railways were also nationalised, and their reconstruction was given priority over the maintenance of the Underground and most of the unfinished plans of the pre-war New Works Programme were shelved or postponed. The District line needed new trains and an unpainted aluminium train entered service in 1953, this becoming the standard for new trains. In
28054-410: Was founded in 1565 by Sir Thomas Gresham as a centre of commerce for London's merchants, and gained Royal patronage in 1571. Although no longer used for its original purpose, its location at the corner of Cornhill and Threadneedle Street continues to be the geographical centre of the city's core of banking and financial services, with the Bank of England moving to its present site in 1734, opposite
28223-436: Was transferred to the Jubilee line in 1979.) In 1936, the line was extended east from Whitechapel to Barking along the tracks of the District line. London Transport inherited incompatible electric multiple units from the railway, including the 1927–33 multiple-unit compartment stock used on routes to Watford and Rickmansworth, and these were refurbished to form a uniform fleet and designated London Underground T Stock . In
28392-420: Was undredged and thus wider than it is today, with Londinium's shoreline slightly north of the city's present shoreline. The Romans built a bridge across the river, as early as AD 50, near to today's London Bridge. By the time the London Wall was constructed, the city's fortunes were in decline, and it faced problems of plague and fire. The Roman Empire entered a long period of instability and decline , including
28561-403: Was used for two years in the development of the first underground train, and was later, in 1861, filled up. The world's first underground railway, it opened in January 1863 between Paddington and Farringdon using gas-lit wooden carriages hauled by steam locomotives. It was hailed as a success, carrying 38,000 passengers on the opening day, and borrowing trains from other railways to supplement
