A conurbation is a region comprising a number of metropolises , cities, large towns, and other urban areas which, through population growth and physical expansion, have merged to form one continuous urban or industrially developed area. In most cases, a conurbation is a polycentric urbanised area in which transportation has developed to link areas. They create a single urban labour market or travel to work area .
100-524: The Greater London Built-up Area , or Greater London Urban Area , is a conurbation in south-east England that constitutes the continuous urban sprawl of London , and includes surrounding adjacent urban towns as defined by the Office for National Statistics . It is the largest urban area in the United Kingdom with a population of 9,787,426 in 2011. The Greater London Built-up or Urban Area had
200-492: A cost of £1.3 million. In that year, Myles Fenton , then serving as assistant manager of the Lancashire and Yorkshire Railway , was appointed as the first manager of the new company. Board of Trade inspections took place in late December 1862 and early January 1863 to approve the railway for opening. After minor signalling changes were made, approval was granted and a few days of operating trials were carried out before
300-629: A few densely populated outliers connected to it by ribbon development . Its outer boundary is constrained by the Metropolitan Green Belt and it is therefore much smaller than the wider metropolitan area of London. As a selective grouping of relatively low- to mid-density (and some high-density) output areas , each consisting of roughly 120 households, it can be compared to the London region, which covers 1,572 square kilometres (607 sq mi) and contained 8,173,194 residents at

Trial runs were carried out from November 1861 while construction was still under way. The first trip over the whole line was in May 1862 with William Gladstone among the guests. By the end of 1862, work was complete at

By then raising money was becoming very difficult although there was local support for a station at Chesham . Authorised in 1885, double track from Rickmansworth was laid for 5 miles (8.0 km), then single to Chesham. Services to Chesham calling at Chorley Wood and Chalfont Road (now Chalfont & Latimer ) started on 8 July 1889. The Met took over

Land values here were higher and, unlike the original line, the route did not follow an easy alignment under existing roads. Compensation payments for property were much higher. In Leinster Gardens , Bayswater, a façade of two five-storey houses
1300-562: A southern extension to Rickmansworth, connecting with the LNWR's Watford and Rickmansworth Railway . Following discussions between the duke and Watkin it was agreed that this line would be extended south to meet the Met at Harrow and permission for this extension was granted in 1874 and Watkin joined the board of the A&BR in 1875. Money was not found for this scheme and the Met had to return to Parliament in 1880 and 1881 to obtain permission for
1400-426: A temporary platform at Finchley Road . Double track and a full service to Willesden Green started on 24 November 1879 with a station at Kilburn & Brondesbury (now Kilburn ). The line was extended 5 miles 37.5 chains (8.80 km) to Harrow , the service from Baker Street beginning on 2 August 1880. The intermediate station at Kingsbury Neasden (now Neasden ) was opened the same day. Two years later,

The company's name was also to be changed again, to Metropolitan Railway. royal assent was granted to the Metropolitan Railway Act 1854 ( 17 & 18 Vict. c. ccxxi) on 7 August 1854. Construction of the railway was estimated to cost £1 million. Initially, with the Crimean War under way, the Met found it hard to raise
2000-580: The Great Northern and Metropolitan Junction Railway Act 1860 ( 23 & 24 Vict. c. clxviii). The GWR agreed to contribute £175,000 and a similar sum was promised by the GNR, but sufficient funds to make a start on construction had not been raised by the end of 1857. Costs were reduced by cutting back part of the route at the western end so that it did not connect directly to the GWR station, and by dropping

Former Met tracks and stations are used by the London Underground 's Metropolitan , Circle , District , Hammersmith & City , Piccadilly , Jubilee and Victoria lines, and by Chiltern Railways and Great Northern . In the first half of the 19th century the population and physical extent of London grew greatly. The increasing resident population and
2300-747: The Met ) was a passenger and goods railway that served London from 1863 to 1933, its main line heading north-west from the capital's financial heart in the City to what were to become the Middlesex suburbs. Its first line connected the main-line railway termini at Paddington , Euston , and King's Cross to the City. The first section was built beneath the New Road using cut-and-cover between Paddington and King's Cross and in tunnel and cuttings beside Farringdon Road from King's Cross to near Smithfield , near
2400-410: The River Thames . The area uses around 4 gigawatts of electricity power. The density gradient of industrialising cities has tended to follow a specific pattern: the density of the centre of the city would rise during urbanisation and the population would remain heavily concentrated in the city centre with a rapid decline in settlement towards the periphery. Then, with continued economic growth and

The extension to Aldersgate Street and Moorgate Street (now Barbican and Moorgate ) had opened on 23 December 1865 and all four tracks were open on 1 March 1866. The new tracks from King's Cross to Farringdon were first used by a GNR freight train on 27 January 1868. The Midland Railway junction opened on 13 July 1868 when services ran into Moorgate Street before its St Pancras terminus had opened. The line left
2600-538: The South Eastern Railway (SER), and had an aspiration to construct a line from the north through London to that railway. Owing to the cost of land purchases, the Met's eastward extension from Moorgate Street was slow to progress and it had to obtain an extension of the Act's time limit in 1869. The extension was begun in 1873, but after construction exposed burials in the vault of a Roman Catholic chapel,
2700-641: The 20 Outer London boroughs. In the 2011 census, the following areas were considered to be built-up areas but outside the Greater London Built-up Area, despite being within Greater London . All of these areas had populations of less than a thousand except New Addington BUA and Harefield BUA which had populations of 22,280 and 6,573 respectively. Note that these are Built-up areas as defined by Office for National Statistics and will have different boundaries from

In 1894, the Met and GWR joint station at Aylesbury opened. Beyond Aylesbury to Verney Junction, the bridges were not strong enough for the Met's locomotives. The GWR refused to help, so locomotives were borrowed from

By the early twentieth century, amid increasing middle-class affluence, large low-density suburbs of semi-detached houses had sprung up all around the city, doubling the area of built-up London in the interwar period alone, despite the population increase is just 10%. H. G. Wells even predicted in 1902 that within

In 1873, the M&SJWR was given authority to reach the Middlesex countryside at Neasden, but as the nearest inhabited place to Neasden was Harrow it was decided to build the line 3.5 miles (5.6 km) further to Harrow and permission was granted in 1874. To serve the Royal Agricultural Society 's 1879 show at Kilburn, a single line to West Hampstead opened on 30 June 1879 with

The plan was supported by the City, but the railway companies were not interested and the company struggled to proceed. The Bayswater, Paddington, and Holborn Bridge Railway Company was established to connect the Great Western Railway 's (GWR's) Paddington station to Pearson's route at King's Cross. A bill was published in November 1852 and in January 1853

3200-601: The City Widened Lines, were used mainly by other railway companies. A pair of single-track tunnels at King's Cross connecting the GNR to the Met opened on 1 October 1863 when the GNR began running services, the GWR returning the same day with through suburban trains from such places as Windsor. By 1864 the Met had sufficient carriages and locomotives to run its own trains and increase the frequency to six trains an hour. On 1 January 1866, LC&DR and GNR joint services from Blackfriars Bridge began operating via

The line was soon extended from both ends, and northwards via a branch from Baker Street . Southern branches, directly served, reached Hammersmith in 1864, Richmond in 1877 and the original completed the Inner Circle in 1884. The most important route
3400-638: The GWR Addison Road service was extended over the District Railway via Earl's Court to Mansion House . This became known as the Middle Circle and ran until January 1905; from 1 July 1900 trains terminated at Earl's Court. Additional stations were opened at Westbourne Park (1866), Latimer Road (1868), Royal Oak (1871), Wood Lane (1908) and Goldhawk Road (1914). Between 1 October 1877 and 31 December 1906, some services on
3500-699: The GWR withdrew its stock in August 1863. The Met continued operating a reduced service using GNR standard-gauge rolling stock before purchasing its own standard-gauge locomotives from Beyer, Peacock and Company and rolling stock. The Metropolitan initially ordered 18 tank locomotives, of which a key feature was condensing equipment which prevented most of the steam from escaping while trains were in tunnels; they have been described as "beautiful little engines, painted green and distinguished particularly by their enormous external cylinders." The design proved so successful that eventually 120 were built to provide traction on
3600-453: The H&CR became jointly owned by the two companies. The GWR began running standard-gauge trains and the broad gauge rail was removed from the H&CR and the Met in 1869. In 1871, two additional tracks parallel to the GWR between Westbourne Park and Paddington were brought into use for the H&CR and in 1878 the flat crossing at Westbourne Park was replaced by a diveunder . In August 1872,
3700-454: The H&CR were extended to Richmond over the London and South Western Railway (L&SWR) via its station at Hammersmith (Grove Road) . The early success of the Met prompted a flurry of applications to Parliament in 1863 for new railways in London, many of them competing for similar routes. To consider the best proposals, the House of Lords established a select committee , which issued
3800-479: The LNWR until two D Class locomotives were bought. The line was upgraded, doubled and the stations rebuilt to main-line standards, allowing a through Baker Street to Verney Junction service from 1 January 1897, calling at a new station at Waddesdon Manor , a rebuilt Quainton Road , Granborough Road and Winslow Road . From Quainton Road, the Duke of Buckingham had built a 6.5-mile (10.5 km) branch railway,

The Wycombe Railway built a single-track railway from Princes Risborough to Aylesbury and when the GWR took over this company it ran shuttles from Princes Risborough through Aylesbury to Quainton Road and from Quainton Road to Verney Junction. The A&BR had authority for

After an official opening ceremony on 17 September and trial running a circular service started on Monday 6 October 1884. On the same day the Met extended some H&CR services over the ELR to New Cross, calling at new joint stations at Aldgate East and St Mary's. Joint stations opened on

To complete the circuit,

This led to an 1897 Board of Trade report, which reported that a pharmacist was treating people in distress after having travelled on the railway with his 'Metropolitan Mixture'. The report recommended more openings be authorised but the line
4700-612: The Metropolitan & St John's Wood Railway (M&SJWR) opened a single-track railway in tunnel to Swiss Cottage from new platforms at Baker Street (called Baker Street East). There were intermediate stations at St John's Wood Road and Marlborough Road , both with crossing loops, and the line was worked by the Met with a train every 20 minutes. A junction was built with the Inner Circle at Baker Street, but there were no through trains after 1869. The original intention of

This 4-4-0 tank engine can therefore be considered as the pioneer motive power on London 's first underground railway; ultimately, 148 were built between 1864 and 1886 for various railways, and most kept running until electrification in 1905. In the belief that it would be operated by smokeless locomotives,

Internationally the term " urban agglomeration " is often used to convey a similar meaning to "conurbation". A conurbation should be contrasted with a megalopolis . In a megalopolis the urban areas are close but not physically contiguous, and
5000-489: The WLR. There were no intermediate stations and at first this service operated as a shuttle from Gloucester Road. By mid-1869 separate tracks had been laid between South Kensington and Brompton and from Kensington (High Street) to a junction with the line to West Brompton. During the night of 5 July 1870 the District secretly built the disputed Cromwell curve connecting Brompton and Kensington (High Street). East of Westminster,
5100-428: The built-up central area. The concept of an underground railway linking the City with the mainline termini was first proposed in the 1830s. Charles Pearson , Solicitor to the City, was a leading promoter of several schemes and in 1846 proposed a central railway station to be used by multiple railway companies. The scheme was rejected by the 1846 commission, but Pearson returned to the idea in 1852 when he helped set up

All appealed and were allowed, in 1874, to settle for a much lower amount. In October 1872, to restore shareholders' confidence, Edward Watkin was appointed chairman and the directors were replaced. Watkin was an experienced railwayman and already on the board of several railway companies, including
5300-498: The capital. While it attempted to raise the funds it presented new bills to Parliament seeking an extension of time to carry out the works. In July 1855, the Metropolitan Railway (Deviation) Act 1855 ( 18 & 19 Vict. c. cii), which made a direct connection to the GNR at King's Cross, received royal assent. The plan was modified by the Metropolitan (Great Northern Branch and Amendment) Act 1856 and again later by

The Met's Tower of London station closed on 12 October 1884 after the District refused to sell tickets to the station. Initially, the service was eight trains an hour, completing the 13 miles (21 kilometres) circle in 81–84 minutes, but this proved impossible to maintain and so the frequency was reduced to six trains an hour - albeit with an improved timing of 70 minutes - in 1885. Guards were permitted no relief breaks during their shift until September 1885, when they were permitted three 20-minute breaks. In April 1868,

This dropped the City terminus and extended the route south from Farringdon to the General Post Office in St. Martin's Le Grand . The route at the western end was also altered so that it connected more directly to the GWR station. Permission was sought to connect to the London and North Western Railway (LNWR) at Euston and to

After successful lobbying, the company secured parliamentary approval under the name of the "North Metropolitan Railway" in mid-1853. The bill submitted by the City Terminus Company was rejected by Parliament, which meant that the North Metropolitan Railway would not be able to reach the City: to overcome this obstacle,

The railway was initially worked by GWR broad-gauge Metropolitan Class tank locomotives and rolling stock. Soon after the opening, disagreement arose between the Met and the GWR over the need to increase the frequency, and

The congested streets and the distance to the City from the stations to the north and west prompted many attempts to get parliamentary approval to build new railway lines into the City. None were successful, and the 1846 Royal Commission on Metropolitan Railway Termini banned construction of new lines or stations in

This point was generally reached when the city reached a certain stage of economic development. In London, this point was reached in the first half of the nineteenth century, in Paris towards the end of the century and in New York City at
6600-552: The expense of construction delayed further progress on the completion of the inner circle. In 1874, frustrated City financiers formed the Metropolitan Inner Circle Completion Railway Company with the aim of finishing the route. This company was supported by the District and obtained parliamentary authority on 7 August 1874. The company struggled to raise the funding and an extension of time was granted in 1876.

Charles Pearson did not live to see the completion of the project; he died in September 1862. The 3.75-mile (6 km) railway opened to the public on 10 January 1863, with stations at Paddington (Bishop's Road) (now Paddington ), Edgware Road , Baker Street , Portland Road (now Great Portland Street ), Gower Street (now Euston Square ), King's Cross (now King's Cross St Pancras ), and Farringdon Street (now Farringdon ). The railway

The District's level of debt meant that the merger was no longer attractive to the Met and did not proceed, so the Met's directors resigned from the District's board. To improve its finances, the District gave the Met notice to terminate

The center and national capital, Jakarta , has a population of 10.3 million within its borders. The second-most populated city in Indonesia, Surabaya , also forms a conurbation known as Gerbangkertosusila with a metropolitan population of about 10 million compared to the city proper of 3 million. Conurbations are also present around Bandung and Medan . The Mumbai Metropolitan Region (MMR) consists of Mumbai and its satellite towns. Developing over
7000-405: The line had been built with little ventilation and a long tunnel between Edgware Road and King's Cross. Initially the smoke-filled stations and carriages did not deter passengers and the ventilation was later improved by making an opening in the tunnel between Gower Street and King's Cross and removing glazing in the station roofs. With the problem continuing after the 1880s, conflict arose between
7100-538: The line south of Farringdon. In 1858, Pearson arranged a deal between the Met and the City of London Corporation whereby the Met bought land it needed around the new Farringdon Road from the City for £179,000 and the City purchased £200,000 worth of shares. The route changes were approved by Parliament in August 1859, meaning that the Met finally had the funding to match its obligations and construction could begin. Despite concerns about undermining and vibrations causing subsidence of nearby buildings and compensating
7200-575: The main line at St Paul's Road Junction, entering a double-track tunnel and joining the Widened Lines at Midland Junction. In November 1860, a bill was presented to Parliament, supported by the Met and the GWR, for a railway from the GWR's main line a mile west of Paddington to the developing suburbs of Shepherd's Bush and Hammersmith , with a connection to the West London Railway at Latimer Road. Authorised on 22 July 1861 in
7300-584: The merging of labour markets has not yet developed. A conurbation should also be contrasted with a megacity . A megacity is hierarchical with an indisputable dominant urban core, whereas a conurbation is polycentric and no single urban centre has the dominant role over all other centres.

7400-408: The mid-nineteenth century, the first major suburban areas were springing up around London as the city (then the largest in the world) became more overcrowded and unsanitary. A major catalyst in the growth in urban sprawl came from the opening of the Metropolitan Railway in the 1860s. The line joined the capital's financial heart in the City to what were to become the suburbs of Middlesex . Harrow
7500-403: The new meat market at Smithfield . The trench was 33 feet 6 inches (10.2 m) wide, with brick retaining walls supporting an elliptical brick arch or iron girders spanning 28 feet 6 inches (8.7 m). The tunnels were wider at stations to accommodate the platforms. Most of the excavation work was carried out manually by navvies ; a primitive earth-moving conveyor
7600-403: The next section of the District's line ran in the new Victoria Embankment built by the Metropolitan Board of Works along the north bank of the River Thames . The line opened from Westminster to Blackfriars on 30 May 1870 with stations at Charing Cross (now Embankment ), The Temple (now Temple ) and Blackfriars . On its opening the Met operated the trains on the District, receiving 55% of
7700-431: The operating agreement. Struggling under the burden of its very high construction costs, the District was unable to continue with the remainder of the original scheme to reach Tower Hill and made a final extension of its line just one station east from Blackfriars to a previously unplanned City terminus at Mansion House . On Saturday 1 July 1871, an opening banquet was attended by Prime Minister William Gladstone , who
7800-511: The railway east of Mansion House were allowed to lapse. At the other end of the line, the District part of South Kensington station opened on 10 July 1871 and Earl's Court station opened on the West Brompton extension on 30 October 1871. In 1868 and 1869, judgements had been against the Met in a number of hearings, finding financial irregularities such as the company paying a dividend it could not afford and expenses being paid out of
7900-520: The services, though electrification of outlying sections did not occur until decades later. Unlike other railway companies in the London area, the Met developed land for housing, and after World War I promoted housing estates near the railway using the " Metro-land " brand. On 1 July 1933, the Met was amalgamated with the Underground Electric Railways Company of London and the capital's tramway and bus operators to form
8000-810: The settlements after which they are named. At the time of the 2001 Census, the Office for National Statistics defined the Greater London Urban Area as being made up of the following components: Within the region, there were 33 components corresponding to the City of London and the London boroughs. However, the ONS boundaries are not identical to the local authority boundaries, and outlying areas such as Biggin Hill in Bromley are omitted.

8100-670: The shops; two years later land was given to the Wesleyan Church for a church building and a school for 200 children. In 1868, the Duke of Buckingham opened the Aylesbury and Buckingham Railway (A&BR), a 12.75-mile (20.5 km) single track from Aylesbury to a new station at Verney Junction on the Buckinghamshire Railway 's Bletchley to Oxford line. At the beginning lukewarm support had been given by
8200-412: The single-track tunnel between Baker Street and Swiss Cottage was duplicated and the M&SJWR was absorbed by the Met. In 1882, the Met moved its carriage works from Edgware Road to Neasden. A locomotive works was opened in 1883 and a gas works in 1884. To accommodate employees moving from London over 100 cottages and ten shops were built for rent. In 1883, a school room and church took over two of
8300-848: The state, Amaravati , is being developed between the cities of Vijayawada and Guntur at the center of the conurbation. The region holds a total population of 58 lakhs.

8400-826: The term in his book Cities in Evolution (1915). He drew attention to the ability of the new technology at the time of electric power and motorised transport to allow cities to spread and agglomerate together, and gave as examples " Midlandton " in England, the Ruhr in Germany, Randstad in the Netherlands, and the Northeastern Seaboard in the United States. The term as described is used in Britain whereas in
8500-456: The thousands of people whose homes were destroyed during the digging of the tunnel, construction began in March 1860. The line was mostly built using the " cut-and-cover " method from Paddington to King's Cross; east of there it continued in a 728 yards (666 m) tunnel under Mount Pleasant, Clerkenwell then followed the culverted River Fleet beside Farringdon Road in an open cutting to near
8600-664: The time of the 2011 census. The built-up area of the Greater London region continues beyond the region's administrative boundary in some places, while stopping short of it in others. For this reason, the density of the Greater London Built-Up Area is 8.3% higher than that of Greater London, the figure for which includes these outlying rural areas (notably in Hillingdon , Enfield , Havering and Bromley ). All of both areas are drained ultimately by
8700-421: The turn of the twentieth. However, London had been sprawling out of its medieval confines within the City since the eighteenth century, when the city experienced its first great urban surge. Areas to the west of Westminster were increasingly built up for the wealthy, to live in the suburbs of the city. A dramatic increase in the city's urban sprawl began in the nineteenth century when labourers flocked from
8800-467: The whole circle. A large contribution was made by authorities for substantial road and sewer improvements. In 1882, the Met extended its line from Aldgate to a temporary station at Tower of London . Two contracts to build joint lines were placed, from Mansion House to the Tower in 1882 and from the circle north of Aldgate to Whitechapel with a curve onto the ELR in 1883. From 1 October 1884, the District and
8900-483: Was also a shareholder. The following Monday, Mansion House opened and the District began running its own trains. From this date, the two companies operated a joint Inner Circle service between Mansion House and Moorgate Street via South Kensington and Edgware Road every ten minutes, supplemented by a District service every ten minutes between Mansion House and West Brompton and H&CR and GWR suburban services between Edgware Road and Moorgate Street. The permissions for
9000-464: Was authorised in May 1865. This appeared on some maps. Financial difficulties meant the scope of the line only progressed as far as Swiss Cottage, The branch to Hampstead was cancelled in 1870. A 156 yards (143 m) section of tunnel was built north of Swiss Cottage station for the Hampstead branch most of which was used for the later extension to the north-west. A short length towards Hampstead
9100-410: Was built at Nos. 23 and 24 to conceal the gap in a terrace created by the railway passing through. To ensure adequate ventilation, most of the line was in cutting except for a 421-yard (385 m) tunnel under Campden Hill . Construction of the District proceeded in parallel with the work on the Met and it too passed through expensive areas. Construction costs and compensation payments were so high that
9200-479: Was electrified before these were built. With connections to the GWR and GNR under construction and connections to the Midland Railway and London, Chatham and Dover Railway (LC&DR) planned, the Met obtained permission in 1861 and 1864 for two additional tracks from King's Cross to Farringdon Street and a four-track eastward extension to Moorgate . The Met used two tracks: the other two tracks,
9300-427: Was hailed a success, carrying 38,000 passengers on the opening day, using GNR trains to supplement the service. In the first 12 months 9.5 million passengers were carried and in the second 12 months this increased to 12 million. The original timetable allowed 18 minutes for the journey. Off-peak service frequency was every 15 minutes, increased to ten minutes during the morning peak and reduced 20 minutes in
9400-411: Was intended that they would soon merge. The Met's chairman and three other directors were on the board of the District, John Fowler was the engineer of both companies and the construction works for all of the extensions were let as a single contract. The District was established as a separate company to enable funds to be raised independently of the Met. Starting as a branch from Praed Street junction,
9500-474: Was northwest into the Middlesex countryside, stimulating the development of new suburbs. Harrow was reached in 1880, and from 1897, having achieved the early patronage of the Duke of Buckingham and the owners of Waddesdon Manor , services extended for many years to Verney Junction in Buckinghamshire . Electric traction was introduced in 1905, and by 1907 electric multiple units operated most of
9600-414: Was not used again by regular traffic. During the extension of the railway to Aldgate several hundred cartloads of bullocks' horn were discovered in a layer 20 ft (6.1 m) below the surface. A terminus opened at Aldgate on 18 November 1876, initially for a shuttle service to Bishopsgate before all Met and District trains worked through from 4 December. Conflict between the Met and the District and
9700-520: Was not without incident. In May 1860, a GNR train overshot the platform at King's Cross and fell into the workings. Later that year, a boiler explosion on an engine pulling contractor's wagons killed the driver and his assistant. In May 1861, the excavation collapsed at Euston causing considerable damage to the neighbouring buildings. The final accident occurred in June 1862 when the Fleet sewer burst following
9800-402: Was reached in 1880, and the line eventually extended as far as Verney Junction in Buckinghamshire , more than 50 miles (80 kilometres) from Baker Street and the centre of London. Unlike other railway companies, which were required to dispose of surplus land, the Met was allowed to retain such land that it believed was necessary for future railway use. Initially, the surplus land was managed by
9900-408: Was unused. This is still visible today when travelling on a southbound Metropolitan line service. In the early 1870s, passenger numbers were low and the M&SJWR was looking to extend the line to generate new traffic. Recently placed in charge of the Met, Watkin saw this as the priority as the cost of construction would be lower than in built-up areas and fares higher; traffic would also be fed into
10000-462: Was used to remove excavated soil from the trench. Within the tunnel, two lines were laid with a 6-foot (1.8 m) gap between. To accommodate both the standard gauge trains of the GNR and the broad gauge trains of the GWR, the track was three-rail dual gauge , the rail nearest the platforms being shared by both gauges. Signalling was on the absolute block method, using electric Spagnoletti block instruments and fixed signals. Construction
