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. Coloured magenta on the tube map, the line is 41.4 miles (66.7 km) in length and serves 34 stations. Between Aldgate and Finchley Road 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 67 million passenger journeys were made on the line in 2011/12.

The line is one of just two Underground lines to cross the Greater London boundary (the other being the Central line). It is the only Underground line with an express service at peak times; the resulting longer distance between stations means trains can achieve the system's highest speeds of over 60 miles per hour (100 km/h) on some sections.

In 1863 the Metropolitan Railway began the world's first underground railway between Paddington and Farringdon with wooden carriages and steam locomotives, but its most important route became the line north 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 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 the A Stock trains, that served the line since 1961.

The section between Aldgate and Baker Street is shared with the Circle and Hammersmith & City sub-surface lines; between Rayners Lane and Uxbridge with the Piccadilly line; and between Harrow-on-the-Hill and Amersham with the Chiltern Railways London to Aylesbury Line. Baker Street 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: the inner pair was transferred to the Bakerloo line in 1939 (becoming the Jubilee line in 1979) with services calling at all stations. The disused Metropolitan line platforms at Willesden Green and Neasden are still in place despite Metropolitan line services having been withdrawn in 1940.

History

Metropolitan Railway

Main article: Metropolitan Railway

Construction of the Metropolitan line near King's Cross station (1861)

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 the City, built beneath the New Road using the cut-and-cover method between Paddington and King's Cross, and in tunnel and cuttings beside Farringdon Road from King's Cross to near Smithfield. 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 the peak periods.^[2][3][4] In the 1871 plans for an underground railway in Paris, it was called the Métropolitain.^[5]

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,^[6] but the most important route became the line west and north-west into the Middlesex countryside, where it stimulated 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.^[7]

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 the tunnels in central London, the railway purchased electric locomotives, exchanged for steam locomotives at Harrow from 1908.^[8] In 1910, a seventeen-minute silent film recording was made showing large portions of the journey from Baker Street to Aylesbury and Uxbridge, seen from the cab of a train. The film survives and is publicly available.^[9]

Unlike other railways in the London area, the Met developed land for housing, thus benefitting from the increase in 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.^[10]

On 1 July 1933 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 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^[11] though services returned to Quainton Road between 1943 and 1948.^[12]

A stock at Amersham

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 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.^[13] (This route was transferred to the Jubilee line in 1979.)^[14] In 1936 the line was extended east from Whitechapel to Barking along the tracks of the District line.^[15] London Transport inherited a number of 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.^[16] In the 1950s, F Stock trains, with sliding doors under the control of the guard, were transferred from the District line; these mainly worked the semi-fast Harrow and Uxbridge services.^[17]

A major rebuilding of the main line from Wembley Park to Amersham was planned in the 1930s but delayed by the war. The line from Wembley to Harrow was rebuilt immediately after the war and the project was completed from 1956–1962, on 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.^{[18][failed verification]} Aluminium A stock, originally unpainted, replaced 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 4-car units that could operate as four- or eight-car trains;^[19] normally operated as eight cars, a 4-car unit operated the Chesham shuttle.^[20] One person operation of the trains was proposed in 1972, but due to conflict with the trades unions was not introduced on the line until 1986.^[21]

Although the East London line had been an isolated shuttle since 1939,^[15] it was shown on London Underground maps as part of the Metropolitan line until 1968.^[22] In 1970 it was shown with a thin white line in the middle and labelled the "East London section".^[23] By the 1985 map it had become the "East London Line", remaining the same colour as the Metropolitan line with a white line in the middle,^[24] changed to orange by the 1990 map.^[25] 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.^[15][25]

In 2003, the infrastructure was partly privatised in a public–private partnership managed by the Metronet consortium. Metronet went into administration in 2007 and Transport for London took over responsibilities.^[26]

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.^[27] The final passenger services operated by the A Stock ran on 26 September 2012,^[28] followed by a ticketed public railtour on 29 September.^[29]

The Metropolitan line is 42 miles (67 km) long and serves 34 stations.^[30] It is electrified with a four-rail DC system: a central conductor rail is energised at –250 V and a rail outside the running rail at +500 V, giving a potential difference of 750 V, except for the section from Uxbridge to Finchley Road (via Harrow-on-the-Hill) which is energised at –210 V and +420 V respectively (630 V potential difference) to maintain compatibility with 1973 Stock and 1996 Stock that runs in those areas.^[31][32] The first 6 miles (9.7 km) from Aldgate are below ground,^[33] shared with the Circle and Hammersmith & City lines to Baker Street, where the line diverges, remaining in tunnel until Finchley Road.^[34] Metropolitan line trains then run express from Finchley Road to Wembley Park, with the Jubilee line serving the intermediate stations. At Wembley Park 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.^[34]

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 Chiltern Main Line. The slow lines are between the fast lines, and the two intermediate stations have island platforms.^[34] Harrow-on-the-Hill has platforms on all six lines.^[34] 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.^[34][35]

On 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 Chiltern line services from Marylebone; the eastern slow tracks have platforms at the intermediate stations. There is access at Watford triangle to the Watford branch.^[34] This double-track branch has stations at Croxley and Watford.^[34][36] 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 a distance.^[30][34] 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.^[37]

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.^[38] The upper two lights are a two-aspect stop signal displaying either 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.^[38]

The Metropolitan line's suburban rail character opposed to other London Underground lines is also shown by the long distances between stops. Eight of the top 10 furthest apart stations on the Underground are on the Metropolitan line. The section between Chalfont & Latimer and Chesham is the longest at 3.9 miles (6.3 km),^[39] whilst the Finchley Road to Wembley Park section is the second longest, and Rickmansworth to Chorleywood the fourth longest overall.

Services

The Metropolitan line is 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).^[40] Depending on 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:

• All-stations services call at all stations en route^[40]
• Semi-fast services run non-stop between Wembley Park and Harrow-on-the-Hill, and call at all other stations en route^[40]
• Fast services run non-stop between Wembley Park and Harrow-on-the-Hill and between Harrow-on-the-Hill and Moor Park^[40]
• In the southbound direction, fast and semi-fast trains do not call at Wembley Park and run non-stop from Harrow-on-the-Hill to Finchley Road^[40]

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 is not directly connected with the fast line at Moor Park.^[41]

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.^[40]

Frequency

During the off-peak the service pattern on the line, in trains per hour (tph), is as follows:^[40]

• 8tph Aldgate - Uxbridge (all stations);
• 4tph Baker Street - Watford (all stations);
• 2tph Aldgate - Amersham (all stations);
• 2tph Aldgate - Chesham (all stations).

These services combine to give a total frequency of 16tph between Baker Street and Wembley Park. Of these, 12tph run between Aldgate and Baker Street which, together with the 6tph frequencies on both the Circle and Hammersmith & City lines,^[42] 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 is strengthened to the following:^[40]

• 4tph Uxbridge - Baker Street (all stations);
• 6tph Uxbridge - Aldgate (4 all stations, 2 semi-fast);
• 6tph Watford - Baker Street (3 all stations, 3 semi-fast);
• 2tph Watford - Aldgate (1 all stations, 1 semi-fast);
• 4tph Amersham - Aldgate (2 semi-fast, 2 fast)
• 2tph Chesham - Aldgate (fast).

The northbound frequencies in the morning peak are similar on each route, except all trains run as all-stations services.

Similarly, in the evening peak, the northbound service pattern is strengthened to the following:^[40]

• 3tph Baker Street - Uxbridge (all stations);
• 7tph Aldgate - Uxbridge (all stations);
• 4tph Baker Street - Watford (2 all stations, 2 semi-fast)
• 4tph Aldgate - Watford (semi-fast);
• 2tph Baker Street - Amersham (semi-fast);
• 2tph Aldgate - Amersham (fast);
• 2tph Aldgate - Chesham (fast).

The southbound frequencies in the evening peak are similar on each route, except all trains run as all-stations services.

Rolling stock

Main article: London Underground S7 and S8 Stock

S8 Stock trains featuring partial transverse seating, a reminiscence of the older A Stock trains

Since 20 September 2012 all services have been provided by eight-car S Stock trains^[43] introduced in July 2010 to replace the 1960s A Stock.^[44] Part of Bombardier's Movia family, they have air-conditioning, feasible because the sub-surface tunnels, unlike tube tunnels, are able to disperse the exhausted hot air.^[45][46] They have regenerative brakes, returning around 20% of their energy to the network and thus reducing energy consumption.^[47] With fewer seats than the older A Stock – 306 compared with 448 – they can accommodate 697 standing passengers, compared with 597 in A Stock,^{[note 1]} and have dedicated space for wheelchairs.^[48] They have a top speed of 62 miles per hour (100 km/h),^[45] 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.

It is planned to increase the traction voltage from the present nominal 630 V to 750 V to give better performance and allow the trains to return more energy to the network through their regenerative brakes.^[49]

Depot

Main article: Neasden Depot

The line is served by a depot at Neasden.^{[note 2]} The Metropolitan Railway opened a carriage works at Neasden in 1882 and the following year the locomotive works were moved from Edgware Road.^[50] In 1904–05 the depot was refitted to take the new electric multiple units^[51] and accommodation enlarged in 1932–3.^[52] After the amalgamation into the LTPB, the depot was rebuilt from 1936 to 1939. The depot was upgraded in 2010–11 to make it suitable for maintenance of S Stock trains.^[53] Trains are also stabled overnight at Uxbridge, Watford, Rickmansworth and Wembley Park.^[54]

Steam on the Met

LMS Black 5 44932 at Amersham in 1992

In 1989, to celebrate the 100th anniversary of the opening of the Metropolitan to Chesham, the first Steam on the Met event took place with London Underground running two weekends of steam specials between Chesham and Watford.^[55] The event was a success and so in 1990 London Underground ran steam between Harrow and Amersham. In 1992, to celebrate 100 years of the Met at Amersham, the event was extended to five days at 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.^{[citation needed]} In 1995 trains ran between Amersham and Watford.^[56]

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 the imminent partial privatisation of LUL and the stock condition, the last steam excursion took place in 2000.^{[citation needed]} In 2008, special trains ran on using Metropolitan Railway electric locomotive "Sarah Siddons" and diesel Class 20 locomotives.^[57]

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".^[58] Further events are planned in 2013 for Locomotive No. 1, "Sarah Siddons" and the Jubilee carriage, including a Steam back on the Met scheduled for May.^[59]

Four Lines Modernisation (4LM)

It was planned that a new signalling system would be used first on the line north of Baker Street from the end of 2016,^[60] but signalling contractor Bombardier was released from its contract by agreement in December 2013 amid heavy criticism of the procurement process^[61] and London Underground subsequently awarded the contract for the project to Thales in August 2015.^[62]

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.^[60][63][64]A single control room for the sub-surface railway opened at Hammersmith on 6 May 2018, and Communications Based Control (CBTC) provided by Thales will progressively replace 'fixed block' signalling equipment dating back the 1940s.^[60][65] Trackside signals with automatic train protection (ATP) will remain on the line north of Harrow-on-the-Hill, shared with Chiltern Railways DMUs.^[60]

The rollout of CBTC has been split into sections, each known as a Signal Migration Area (SMA), and are located on the line as follows:^[66]

Former stations

LT loco L92 at Croxley tip in 1969

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 the line to Verney Junction closing.^[15] 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 the Metropolitan line station.^[13][15] The Bakerloo line service to Stanmore was transferred to the Jubilee line when that line opened in 1979.^[14]

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.^[15]

Goods-only branches

Between Moor Park and Croxley, a short branch ran south-east off 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 a section of the spur line remained visible from a passing train.

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.^[67] The trackbed is now a footpath.^[68]

Although not operated by Metropolitan passenger services, the line from South Harrow to Rayners Lane was built by the Metropolitan railway as the District Railway was in financial difficulties at the time. This included a short branch, part of which is still visible, on a viaduct to a gas works. Other minor freight connections along the line once included connections to the Midland main line at Finchley Road.

A single-track spur from a small yard between Ickenham and Ruislip stations connects to Ruislip Depot of the Central line. This line is used for engineering and empty stock transfers, although occasional plans suggest extending the Central line into Uxbridge by upgrading the connection. It was built in 1973.

Metropolitan line extension

Main article: Croxley Rail Link

Diagram of the Croxley Rail Link

Also known as the Croxley Rail Link, an extension to the Metropolitan line was to reroute the Watford branch from the current terminus using the disused Croxley Green branch line to Watford Junction. Funding was agreed in December 2011^[69] and the necessary permission was granted by the UK Government in July 2013.^[70][36][71] Due to a funding shortfall, the project was cancelled in 2016.^[71]
