The '''Bakerloo line''' ({{IPAc-en|ˌ|b|eɪ|k|ər|ˈ|l|uː}}) is a [[London Underground]] line that runs between {{stn|Harrow & Wealdstone}} in suburban north-west London and {{lus|Elephant & Castle}} in south London, via the [[West End of London|West End]]. Printed in brown on the [[Tube map]], it serves 25 stations, 15 of which are underground, over {{convert|14.4|mi|km|order=flip}}. It runs partly on the surface and partly through deep-level tube tunnels.

The line's name is a [[portmanteau]] of its original name, the [[Baker Street and Waterloo Railway]].<ref>{{Cite web |title=The Bakerloo line |url=https://www.ltmuseum.co.uk/collections/stories/transport/bakerloo-line |access-date=27 March 2022 |website=London Transport Museum |language=en}}</ref> From {{stn|Queen's Park||England}} to [[Harrow & Wealdstone station|Harrow & Wealdstone]] (the section above ground), the line shares tracks with the [[London Overground]] [[Lioness line]] and runs parallel to the [[West Coast Main Line]]. There is, however, a short tunnel at the western end of {{stn|Kensal Green}}.

Opened between 1906 and 1915, many of its stations retain elements of their design to a common standard: the stations below ground using [[Art Nouveau]] decorative tiling by [[Leslie Green]], and the above-ground stations built in red brick with stone detailing in an [[Arts and Crafts movement|Arts & Crafts]] style. It is the ninth-busiest line on the network, carrying more than 125 million passengers annually.

The line currently runs [[London Underground 1972 Stock|1972 Stock]] trains which, at {{age|1972|6|26}} years old, are the oldest trains in regular passenger service in Britain.

==History==
{{Further|Baker Street and Waterloo Railway}}
The route had its origins in the failed projects of the pneumatic 1865 [[Waterloo and Whitehall Railway]] and the 1882 Charing Cross and Waterloo Electric Railway.<ref>{{cite web |url=http://www.tfl.gov.uk/tfl/corporate/modesoftransport/tube/linefacts/?line=bakerloo#section-5 |title=An extended history of the Bakerloo line |website=TfL }}</ref>

Originally called the Baker Street & Waterloo Railway, the line was constructed by the [[Underground Electric Railways Company of London]] (UERL) and opened between [[Lambeth North tube station|Lambeth North]] (at the time named ''Kennington Road'') and [[Baker Street tube station|Baker Street]] on 10 March 1906.<ref name=Day>{{cite book |last1=Day |first1=J.R. |last2=Reed |first2=J. |year=2001 |title=The Story of London's Underground |location=Harrow Weald |publisher=Capital Transport Publishing |isbn=978-1-85414-245-0 }}</ref> It was extended eastward to Elephant & Castle five months later, on 5 August. The contraction of the name to "Bakerloo" rapidly caught on, and the official name was changed to match in July 1906.<ref name=Day />

When work on the line started in June 1898, it had been financed by the mining entrepreneur and company promoter [[Whitaker Wright]], who fell foul of the law over the financial proceedings involved and dramatically committed suicide at the [[Royal Courts of Justice]], after being convicted in 1904. As a result, work on the line was stopped for a few months and did not resume until [[Charles Yerkes]] and UERL stepped in and took over the project.<ref name=Day />

By 1913, the line had been extended westward from its original northern terminus at Baker Street, with [[interchange station]]s with the [[Great Central Railway]] at [[Marylebone station|Marylebone]] and with the [[Great Western Railway]] at [[Paddington tube station (Bakerloo, Circle and District lines)|Paddington]], and a new station at [[Edgware Road tube station (Bakerloo line)|Edgware Road]].

===Watford branch===
[[File:Edgware Road (Bakerloo) stn northbound look south.JPG|thumb|The northbound Bakerloo line platform at [[Edgware Road tube station (Bakerloo line)|Edgware Road]]]]
In 1915, the line was extended to {{lus|Queen's Park}}, where it joined the [[London and North Western Railway|LNWR]]'s [[Euston-Watford DC line]] (now part of [[London Overground]]) to {{rws|Watford Junction }}. Bakerloo services to Watford Junction were reduced in the 1960s and cut back in 1982 to {{lus|Stonebridge Park}}.

Services as far as Harrow & Wealdstone were gradually restored from 1984, and in 1989 the present all-day service was instituted.

===Stanmore branch===
By the mid-1930s, the [[Metropolitan line]] was suffering from congestion caused by the limited capacity of its tracks between Baker Street and [[Finchley Road tube station|Finchley Road]] stations. To relieve this pressure, the network-wide [[New Works Programme]] included the construction of new sections of tunnel between the Bakerloo line's platforms at Baker Street and Finchley Road and the replacement of three Metropolitan line stations ({{lus|Lord's}}, {{lus|Marlborough Road}} and {{lus|Swiss Cottage}}) between those points with two new Bakerloo line stations ({{lus|St John's Wood}} and [Swiss Cottage Swiss Cottage]). The Bakerloo line took over the Metropolitan line's service to [[Stanmore tube station|Stanmore]] on 20 November 1939. The branch remained part of the Bakerloo line until 1 May 1979, when similar congestion problems for the Bakerloo line caused by two branches converging at Baker Street led to the creation of the [[Jubilee line]], initially formed by connecting the Stanmore branch to new tunnels bored between Baker Street and {{lus|Charing Cross}}.

When the Bakerloo line was extended to Watford in 1917, it acquired an interchange at Harrow & Wealdstone with another route to Stanmore, the [[Stanmore branch line]]. This branch line was operated by the LNWR and terminated at a separate Stanmore station (later renamed {{rws|Stanmore Village}}). It was closed in 1964, partly due to the success of the rival Metropolitan/Bakerloo Underground line to Stanmore.<ref>{{cite web |title=Disused Stations: Harrow & Wealdstone Station |url=http://www.disused-stations.org.uk/h/harrow_wealdstone/ |url-status=dead |date=12 February 2018 |access-date=12 February 2018 |archive-url=https://web.archive.org/web/20180212135022/http://www.disused-stations.org.uk/h/harrow_wealdstone/ |archive-date=12 February 2018}}</ref>

===Camberwell extension===
{{Main|Bakerloo line extension#Historical extension proposals}}
An extension at the southern end of the line to [[Camberwell]] and [[Denmark Hill]] was proposed and approved in 1931 as part of the ''London Electric Metropolitan District and Central London Railway Companies (Works) Act, 1931''.<ref name=Gazette_1>{{London Gazette |issue=33699 |pages=1809–1811 |date=17 March 1931}}</ref><ref name=Gazette_2>{{London Gazette |issue=33761 |page=6462 |date=9 October 1931}}</ref> In April 1937, the estimated cost of the proposed extension was £5,000,000 (approximately £{{Formatprice|{{Inflation|UK-GDP|5000000|1937}}|0}} today){{Inflation-fn|UK|df=y}} and the [[London Passenger Transport Board]] announced that, due to rising materials prices, the extension had been postponed until the Board's finances improved.<ref>{{cite news |title=Rising Cost of Steel - London Transport Economics - Extensions Delayed |date=10 April 1937 |newspaper=[[The Times]] |page=14 |location=London}}</ref> Apart from the extension of the sidings south of [[Elephant & Castle tube station|Elephant & Castle]], no work on the extension took place before the [[Second World War]], but the powers were renewed by the government in 1947 under the ''Special Enactments (Extension of Time) Act, 1940''.<ref name=Gazett_3>{{London Gazette |issue=38145 |page=5876 |date=12 December 1947}}</ref> A projected extension as far as [[Camberwell]] was shown on a 1949 edition of the Underground map but no further work was done.<ref name="1949map">{{cite web |title=London Tube Map |url=http://homepage.ntlworld.com/clive.billson/tubemaps/1949.html |url-status=dead |date=June 1949 |access-date=13 January 2008 |publisher=London Transport |archive-url=https://web.archive.org/web/20080125074800/http://homepage.ntlworld.com/clive.billson/tubemaps/1949.html |archive-date=25 January 2008 }}</ref> The train describers at [[Warwick Avenue tube station|Warwick Avenue]] station showed ''Camberwell'' as a destination until the 1990s.<ref>{{cite book |last=Garland |first=Ken |title=Mr Beck's Underground Map |publisher=Capital Transport |year=1994 |page=41 |isbn=978-1-85414-168-2}}</ref> Further extensions of the line were considered, south to Peckham Rye in the 1970s, and east to [[London Docklands]] and [[Canary Wharf]] in the 1980s.

===Electricity supply===
One oddity is that, almost from its opening until 1917, the Bakerloo operated with the polarity of the [[Third rail|conductor rail]]s reversed, the outside rail negative and the centre rail positive. This came about because the Bakerloo shared a power source with the [[District Railway]]. On the Bakerloo, the outside conductor rail tended to leak to the tunnel wall, whereas on the District Railway, the centre rail shared a similar problem. The solution was to reverse the polarity on the Bakerloo line, so that the negative rail leaked on both systems.<ref>{{cite web |title=Bakerloo Line, Dates |url=http://www.davros.org/rail/culg/bakerloo.html#dates |url-status=live |work=Clive's Underground Lines Guide |access-date=13 January 2008 |archive-url=https://web.archive.org/web/20080126103530/http://www.davros.org/rail/culg/bakerloo.html |archive-date=26 January 2008}}</ref> In 1917, the two lines were separated when the LNWR began its 'New Line' service between Euston and Watford Junction, which the Bakerloo would share north of Queens Park. As a result, normal operation was restored.

===Centenary===
The line celebrated its centenary on 10 March 2006, when events were organised with actors and staff in Edwardian costume entertaining travellers.<ref name="centenary">{{cite news |title=Tube line's 100 year celebration |url=http://news.bbc.co.uk/1/hi/england/london/4790322.stm |work=[[BBC News]] |location=London |date=10 March 2006 |access-date=<!--13 November 2007-->}}</ref>

===2017 fire===
In 2017, a fire on a train at Oxford Circus station caused disruption on the Bakerloo line. A number of people were treated for the effects of smoke inhalation.<ref>{{Cite news |url= https://www.theguardian.com/uk-news/2017/aug/11/oxford-circus-station-evacuated-rush-hour-bakerloo-line-train-catches-fire |title=Two taken to hospital after fire on rush-hour tube train in London |work=The Guardian |location= London |first=Jamie |last=Grierson |date=11 August 2017}}</ref>

==Future developments==
===Re-extension to Watford Junction===
Operation of the northern section of the line may be changed following the decision in February 2006 to transfer responsibility for Euston-Watford suburban services (on the [[Watford DC Line]]) from the [[Department for Transport]] to [[Transport for London]] (TfL). This was in conjunction with the reorganisation of a number of north London railways under [[London Overground]].<ref name=londonplan>{{cite web |title=Scenario Testing for the Further Alterations to the London Plan |publisher=[[Greater London Authority]] |date=March 2006 |url=http://www.london.gov.uk/archive/mayor/strategies/sds/further-alts/docs/scenarios.pdf |access-date=19 June 2007 |url-status=dead |archive-url=https://web.archive.org/web/20110604094443/http://www.london.gov.uk/archive/mayor/strategies/sds/further-alts/docs/scenarios.pdf |archive-date=4 June 2011 }}</ref><ref>{{cite web |url=http://www.tfl.gov.uk/assets/downloads/businessandpartners/network-rail-rus-response.pdf |archive-url=https://web.archive.org/web/20070930200336/http://www.tfl.gov.uk/assets/downloads/businessandpartners/network-rail-rus-response.pdf |archive-date=30 September 2007 |url-status=live |title=Information on Bakerloo line re-extension to Watford Junction |website=Transport for London }}</ref>

In a former London Plan, it was projected that by 2026 the Bakerloo line would be re-extended from Harrow & Wealdstone to Watford Junction, restoring the pre-1982 service. The railway line from Queens Park to Watford Junction, currently shared with London Overground, would be shared with the Bakerloo line.<ref name=londonplan/> The Best And Final Bid documentation for the [[Croxley Rail Link]] project indicates that this Bakerloo line extension is now "unlikely" because "TfL's plans to extend the Bakerloo line to Watford Junction are on hold indefinitely due to funding and business case constraints".<ref name="CRLBABFVFM">{{cite web |url= http://www.croxleyraillink.com/media/30037/croxley%20rail%20link%20value%20for%20money%20annex.pdf |archive-url=https://web.archive.org/web/20120405231547/http://www.croxleyraillink.com/media/30037/croxley%20rail%20link%20value%20for%20money%20annex.pdf |archive-date=5 April 2012 |url-status=live |title= Croxley Rail Link BAFB Value For Money Annex |year=2011 |publisher=Steer Davis Gleave |access-date=29 November 2011}}</ref>

== Rolling stock ==

=== Current rolling stock ===
{{Main|London Underground rolling stock}}
[[File:72 T INTERIOR Bakerloo line.JPG|thumb|The interior of a Bakerloo line train]]
The Bakerloo line is operated entirely by [[London Underground 1972 Stock|1972 Stock]], displaced from the Jubilee line by [[London Underground 1983 Stock|1983 stock]]. The trains are maintained at Stonebridge Park depot. All Bakerloo line trains are painted in the London Underground livery of red, white and blue, and are the smaller of the two train sizes used on the network, as the line runs deep underground in small-diameter tunnels.

In the early 2000s, the interiors of the trains were 'deep-cleaned' and the upholstery replaced with a blue [[moquette]]. The seating layouts are both longitudinal and transverse; some cars have longitudinal seating only. A TfL Finance and Policy Committee Paper dated 11 March 2015 revealed that the repair programme for the 1972 Stock would be more expensive than anticipated, due to the unexpectedly inferior condition of the fleet.<ref>{{cite web |url= http://cdn.londonreconnections.com/2013/bakerloo-line.pdf |archive-url=https://ghostarchive.org/archive/20221010/http://cdn.londonreconnections.com/2013/bakerloo-line.pdf |archive-date=10 October 2022 |url-status=live |title=Bakerloo Line Fleet Life Extension |date=11 March 2015 |publisher=Transport for London |access-date=23 April 2016}}</ref>

In early 2016, a four-year refurbishment programme began with the first of the new-look cars operating on the line in March.<ref>{{cite news |url= https://www.standard.co.uk/news/transport/a3215311.html#gallery |title= First look at newly-refurbished Bakerloo Line train |date= 31 March 2016 |work= London Evening Standard |access-date= 23 April 2016 |archive-url= https://web.archive.org/web/20160424035416/http://www.standard.co.uk/news/transport/a3215311.html#gallery |archive-date= 24 April 2016 |url-status= dead }}</ref> Each car's interior was cleaned, the seating moquette replaced with a variation of the Barman type seen on other lines, and handrails and lighting renewed. Each car was assessed and repair work carried out to ensure the stock can operate safely.

According to a November 2021 paper by the TfL Finance Committee, replacement of the current trains may not occur until the late 2030s or early 2040s, due to a lack of funding. In this case, the trains would be 60-70 years old at the time of replacement, around twice their design life.<ref>{{Cite web |date=21 November 2021 |title=Impacts of Reduced Funding for TfL |url=https://board.tfl.gov.uk/documents/s16939/fc-20211124-item11a-Impacts-of-Reduced-Funding.pdf |archive-url=https://ghostarchive.org/archive/20221010/https://board.tfl.gov.uk/documents/s16939/fc-20211124-item11a-Impacts-of-Reduced-Funding.pdf |archive-date=10 October 2022 |url-status=live |access-date=17 June 2022 |website=Transport for London}}</ref> Since the withdrawal of the final [[British Rail Class 483|Class 483 trains]] on the Isle of Wight, the 1972 Stock have become the oldest non-heritage trains running in the United Kingdom.<ref>{{cite news |last1=Haigh |first1=Philip |title=All change on the Bakerloo Line for the UK's oldest trains? |work=RAIL |publisher=Bauer Consumer Media |date=13 December 2023 |location=Peterborough |pages=56–57}}</ref>

When opened in 1906, the Bakerloo line was operated by [[London Underground 1906 Stock|Gate Stock]] trains, built at [[Trafford Park]], [[Manchester]]. To cope with the extension to Queen's Park, 12 extra motor cars of the [[London Underground 1914 Stock]] were ordered, ten from [[Brush Traction|Brush]] of [[Loughborough]] and two from the [[Leeds Forge Company]].

To operate services north of Queen's Park, 72 additional cars were built by the [[Metro Cammell|Metropolitan Carriage, Waggon and Finance Company]] of [[Birmingham]]. These trains, known as the [[London Underground Watford Joint Stock|Watford Joint Stock]], were partly owned by the Underground and partly by the London and North Western Railway (later [[London, Midland and Scottish Railway]] (LMS)). They were initially painted in LNWR livery. They were not equipped with air-operated doors and proved slow and unreliable, so they were replaced by new trains of [[London Underground Standard Stock|Standard Stock]] by 1930 (although a few were retained by the LMS). For some years in the 1930s, Watford trains had a distinctive blue stripe at window level.

In 1932, some carriages built for the [[Piccadilly line]] by Cammell Laird in [[Nottingham]] in 1919 were transferred to the Bakerloo line. When built, these had been the first Tube trains to have air-operated doors. These were later replaced by more trains of Standard Stock, in turn being replaced by [[London Underground 1938 Stock|1938 stock]] and [[London Underground 1949 Stock|1949 stock]].

Until the 1980s, the Bakerloo line was mainly worked by 1938 stock. [[London Underground 1972 Stock|1972 stock]] operated briefly on the line during the late 1970s until it was transferred to the [[Jubilee line]] when it opened in 1979. From 1983, the 1938 stock began to be replaced by trains of [[London Underground 1959 Stock|1959 stock]] from the [[Northern line]], but this was a temporary measure until 1972 stock became available. The last 1938 stock train was withdrawn on 20 November 1985. From 1986, the 1959 stock was transferred back to the Northern line and was replaced by the current 1972 stock.<ref>{{cite book |last=Horne |first=M.A.C. |title=The Bakerloo Line |publisher=Capital Transport |year=2001 |isbn=978-1-85414-248-1}}</ref>

===Former stations===

====Watford branch====
{{See also|London Overground|Watford DC Line}}
Between 1917 and 1982, Bakerloo line trains continued along the DC line past Harrow & Wealdstone to Watford Junction. These stations continue to be served by [[Lioness line]]. Proposals have surfaced to re-extend the Bakerloo line to Watford Junction and service the following stations:

==== Stanmore branch ====
{{Main|Jubilee line}}
The [[Stanmore]] branch was originally constructed by the [[Metropolitan Railway]] and was later designated as the '''Stanmore branch''' of the Bakerloo line in 1939. It was transferred to the Jubilee line on 1 May 1979. It connected to the main Bakerloo line at Baker Street.

==Depots==
[[File:Bakerloo line depot at elephant.jpg|thumb|Bakerloo line depot at London Road]]
The Bakerloo line is currently served by three depots: a main depot at [[Stonebridge Park Depot|Stonebridge Park]],{{ref|map 26|map 26}} opened on 9 April 1979 on the site of a former [[British Rail]] power station which contains the fleet's maintenance facilities; the original depot at [[London Road, Southwark|London Road]]{{ref|map 27|map 27}} (between [[Elephant and Castle tube station|Elephant and Castle]] and [[Lambeth North tube station|Lambeth North]], though connected to the line between Lambeth North and Waterloo); and a small depot at [[Queen's Park (London) station|Queens Park station]].

The Queen's Park depot has six tracks, all under cover and numbered 21–26, split between two buildings located at each end of the station, known as the North Shed and the South Shed.<ref>{{cite book |last1=Padgett |first1=David |last2=Kelman |first2=Leanne |editor-last=Munsey |editor-first=Myles |title=Railway Track Diagrams 5: Southern & TfL |edition=4th |date=November 2019 |orig-year=1994 |publisher=Trackmaps |location=Frome |isbn=978-1-9996271-2-6 |at=map 40B }}</ref> The South Shed has two terminal tracks (nos. 25 and 26) and is above the service tracks into the main Bakerloo line tunnels{{ref|map 28|map 28}} built in 1915. The North Shed has two terminal tracks (nos. 22 and 23) and two through tracks (nos. 21 and 24), and is unique on the London Underground network in that trains in passenger service run through it. Tracks 22 and 23 are used by trains from the south terminating at Queen's Park during service. All four tracks in the north shed are also used for stabling trains overnight.

When Bakerloo line services ran to Watford, there was also an additional depot, [[Croxley Green Light Maintenance Depot]] at [[Croxley Green]]; this depot closed in November 1985 following the withdrawal of services.

When the Bakerloo had two branches at its northern end, to Queens Park (as currently) and to Stanmore (now taken over by the Jubilee line), the depot at Neasden on the Stanmore branch was the principal one on the line. The Jubilee taking over this branch from 1979 was the reason behind building the new Stonebridge Park depot.

The London Road depot is unusual in that, although the depot is on the surface, the line passes nearby in tunnel, connected by a short and sharply graded branch tunnel.
