== Background ==
[[File:Elephant & Castle stn Bakerloo east look north.JPG|thumb|[[Elephant & Castle tube station|Elephant & Castle]], the southern terminus of the Bakerloo line]]
Most of the London Underground network lies north of the [[River Thames]], public transport in South London generally being provided by lower-frequency [[National Rail]] suburban services and [[London Buses]].<ref>{{cite map |url= http://content.tfl.gov.uk/london-connections-map.pdf |title=London Connections Map |publisher=[[Transport for London]] |url-status=live |access-date=22 October 2018 |date=May 2014 |archive-url= https://web.archive.org/web/20181022121327/http://content.tfl.gov.uk/london-connections-map.pdf |archive-date=22 October 2018}}</ref><ref>{{cite map |url= http://content.tfl.gov.uk/london-rail-and-tube-services-map.pdf |title=London Rail and Tube Services Map |date=May 2018 |access-date=22 October 2018 |archive-date=22 October 2018 |archive-url= https://web.archive.org/web/20181022121446/http://content.tfl.gov.uk/london-rail-and-tube-services-map.pdf |url-status=live}}</ref>

A large area of South-east London has no rail or tube links, and low [[public transport accessibility level]]s.<ref>{{cite web |title=Blackfriars&nbsp;– Loughborough Junction |url= http://www.abandonedstations.org.uk/Blackfriars_Loughborough.html |access-date=2 October 2009 |website= abandonedstations.org.uk}}</ref><ref>{{Cite web |author= Diamond Geezer |date=15 July 2015 |title=Where in London is over one mile from a station? |url=https://www.google.com/maps/d/viewer?mid=1Qc0XsLq_t_gNu4hkv-b2Dyw8z_o |access-date=28 March 2021 |website= Google My Maps}}</ref><ref name=":10">{{Cite web |last=Aron |first=Isabelle |title=This map shows all the places in London that are more than a mile away from a station |url= https://www.timeout.com/london/blog/this-map-shows-all-the-places-in-london-that-are-more-than-a-mile-away-from-a-station |access-date=28 March 2021 |website=Time Out London |date=21 July 2015}}</ref> This includes places such as Camberwell, [[Walworth, London|Walworth]], [[Burgess Park]] and the Old Kent Road. Existing railway lines through the area – the [[South Eastern Main Line]] and the [[Holborn Viaduct–Herne Hill line]] – are already very crowded and at full capacity. There are also no intermediate stations on main lines through this area.<ref name=":3" /> Furthermore, TfL states that the bus network along the Old Kent Road operates at "close to capacity" with over 60 buses an hour in some sections.<ref name=":11" />

Unlike most Underground lines, the Bakerloo line terminates in [[Travelcard Zone 1|Zone 1]] of London.<ref>{{Cite web |title=Tube and Rail Maps |url= https://tfl.gov.uk/maps/track?intcmp=40400 |url-status=live |access-date=2 April 2021 |publisher=Transport for London|archive-url=https://web.archive.org/web/20170315200714/https://tfl.gov.uk/maps/track?intcmp=40400 |archive-date=15 March 2017 }}</ref> The line is underused compared to other Underground lines.<ref name=":11" /> In 2017, around 110 million journeys were made on it, less than half of those on the [[Central line (London Underground)|Central]], [[Northern line|Northern]], [[Jubilee line|Jubilee]] or [[Victoria line|Victoria]] lines, and passenger growth levels have been lower than on other lines.<ref name=":11" /> TfL believes that the low level of demand on the line is due to its limited connectivity at the southern end, a lower frequency of service compared to other lines (20 trains per hour versus 30+ trains per hour on the Victoria line), and [[London Underground 1972 Stock|the oldest trains on the Underground network]].<ref name=":11" />

==History==
===Prior proposals===
Before the [[Baker Street and Waterloo Railway]] (now the Bakerloo line) opened between [[Baker Street tube station|Baker Street]] and [[Elephant & Castle tube station|Elephant & Castle]] in 1906, several alternative schemes were proposed for extending the line at both ends. One failed scheme, the [[Baker Street and Waterloo Railway#New Cross & Waterloo Railway bill, 1898|New Cross & Waterloo Railway Bill]] of 1898, had proposed the construction of a line as far south as {{rws|Old Kent Road}}, but it was not considered by parliament before it was dropped.{{sfn|Badsey-Ellis|2005|pp=77–78}}

The possibility of building a line through Camberwell first emerged in 1913, when the [[Lord Mayor of London]] announced a proposal for the Bakerloo Tube to be extended to the [[Crystal Palace, London|Crystal Palace]] via [[Camberwell Green]], [[Dulwich]] and [[Sydenham Hill]].{{sfn|Badsey-Ellis|2005|p=268}} In 1921, the [[Underground Electric Railways Company of London]] costed an extension to Camberwell, Dulwich and Sydenham, and in 1922, plans for an extension to [[Orpington]] via Loughborough Junction and [[Catford]] were considered.  No action was taken to move any of these proposals forward. In 1928, a route to [[Rushey Green (ward)|Rushey Green]] via Dulwich was suggested. Again, no action was taken, although the [[London and Home Counties Traffic Advisory Committee]] supported the idea of an extension to Camberwell in 1926.{{sfn|Horne|2001|pp=40–41}}

====1931 and 1947 extension proposals====
{{Bakerloo line extension New Works Plan RDT}}

In 1931, an extension to Camberwell was approved as part of the London Electric Metropolitan District and Central London Railway Companies (Works) Act, 1931.<ref name="Gazette_1">{{London Gazette
| issue = 33699
| date = 17 March 1931
| pages = 1809–1811
}}</ref><ref name="Gazette_2">{{London Gazette
| issue = 33761
| date = 9 October 1931
| page = 6462
}}</ref> The route was to follow [[Walworth Road]] and [[Camberwell Road]] south from Elephant & Castle, with stations at Albany Road and under {{rws|Denmark Hill}} at Camberwell. Elephant & Castle was also to be reconstructed with a third platform to provide the additional turn-round capacity, a new ticket hall and escalators. The need to prioritise the extension from {{lus|Baker Street}} to {{lus|Finchley Road}} to provide relief for the [[Metropolitan line]], financial constraints and the outbreak of the [[Second World War]] prevented any work from starting.{{sfn|Horne|2001|pp=40–41}}

The 1931 enabling 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
| date = 12 December 1947
| page = 5876
}}</ref> and the projected extension as far as Camberwell even appeared on a 1949 edition of the Underground map, but no further work was done.<ref name="1949map">{{cite web|date=June 1949|title=History of the London Tube Map, 1949 tube map|url=http://homepage.ntlworld.com/clive.billson/tubemaps/1949.html|url-status=dead|archive-url=https://web.archive.org/web/20080125074800/http://homepage.ntlworld.com/clive.billson/tubemaps/1949.html|archive-date=25 January 2008|access-date=13 January 2008|publisher=[[London Transport Executive|London Transport]]}}</ref> Train indication signs showing Camberwell as a destination were created in anticipation of the southern extension and erected in some Tube stations; these signs were still visible at {{lus|Warwick Avenue}} until the 1990s.<ref name="lrc-history" /><ref>{{cite book|last=Garland|first=Ken|title=Mr Beck's Underground Map|publisher=Capital Transport|year=1994|isbn=1-85414-168-6|page=41}}</ref> Also, the order for [[London Underground 1949 Stock|1949 Stock]]&nbsp;– built to augment the 1938 stock fleet&nbsp;– included sufficient cars to provide extra trains for the Camberwell extension.

Eventually the proposal faded away. Extensions and new stations were not in favour post-war, as road use increased massively. However, the problem of inadequate turn-round capacity at Elephant & Castle remained. The plan was briefly revived in the 1950s with the intermediate station now to be at [[Walworth, London|Walworth]] and the terminus under Camberwell Green. Elephant & Castle would not be altered and the additional turn-round capacity would be provided by making Camberwell a three-platform terminus.

The original intention to extend to Camberwell was driven by the wish to serve the area, but in the later scheme operational issues were a major consideration. By the time the Bakerloo line branches to {{rws|Watford Junction}} and {{lus|Stanmore}} had opened, the line was running at full capacity, limited by the need to terminate trains at Elephant & Castle. By extending to Camberwell, where there would be three platforms, the whole line would have benefited from an improved frequency. However, "stepping back"<ref>{{cite web|title=Explanation of Stepping Back|url=http://husk.org/www.geocities.com/athens/acropolis/7069/freqs.html|access-date=10 March 2012}}</ref> made the best use of the terminal capacity at Elephant & Castle, and this weakened the case for an extension from Elephant & Castle.

By 1950, post-war austerity, the levelling-off of demand, and above all the disproportionately high cost of the project with a three-platform deep-level terminus and the need to purchase 14 further trains and build a new depot for them, meant that the project became unaffordable and it was cancelled.{{sfn|Horne|2001|p=51}}<ref name=":1">{{Cite news|last=Roberts|first=Jonathan|date=December 2011|title=Extending the Bakerloo – Tube line could reach Hayes|pages=56–59|work=Modern Railways}}</ref> Demand on the Bakerloo line was relieved following construction of the [[Jubilee line]] in the 1970s, as the Stanmore branch now solely served the new Jubilee line.

==== 1970s and 1980s extension proposals ====
In the 1970s, the [[Greater London Council]] considered extending the line to [[Peckham Rye railway station|Peckham Rye]], however this proposal was not taken forward due to high costs, low ridership projections and subsequent poor value for money.<ref name=".alwaystouchout">{{Cite web|title=Bakerloo Line extension to Camberwell|url=http://www.alwaystouchout.com/project/104|access-date=25 September 2018|website=www.alwaystouchout.com|archive-date=28 October 2007|archive-url=https://web.archive.org/web/20071028095714/http://www.alwaystouchout.com/project/104|url-status=dead}}</ref><ref name=":4">{{Cite web|last=Roberts|first=Jonathan|date=13 September 2011|title=Reports of Society Meetings – Beyond the Elephant|url=https://www.lurs.org.uk/articles12_htm_files/2012%2003%20reports%20of%20society%20meetings.pdf|url-status=live|access-date=28 March 2021|website=London Underground Railway Society|archive-url=https://web.archive.org/web/20130709021735/http://lurs.org.uk/articles12_htm_files/2012%2003%20reports%20of%20society%20meetings.pdf |archive-date=9 July 2013 }}</ref><ref name=":1" />

In the late 1980s, following overcrowding in Central London and proposed growth in [[London Docklands|Docklands]], the Central London Rail Study (a joint report of [[Network SouthEast]], [[London Underground]], [[London Regional Transport]] and the [[Department for Transport]]) was commissioned.<ref>{{Cite web|date=January 1989|title=Central London Rail Study|url=https://www.railwaysarchive.co.uk/documents/DoT_CentralLondonRailStudy1989.pdf|url-status=live|access-date=28 March 2021|website=Railways Archive|publisher=[[Network SouthEast]], [[London Underground]], [[London Regional Transport]] and the [[Department for Transport]]|archive-url=https://web.archive.org/web/20130629152424/http://www.railwaysarchive.co.uk/documents/DoT_CentralLondonRailStudy1989.pdf |archive-date=29 June 2013 }}</ref> Within the report, two extensions of the Bakerloo line were considered – an extension to Lewisham along the Old Kent Road, and an extension to [[Canary Wharf]] and Docklands.

====2000s====
In the early 2000s, [[Transport for London]] (TfL) under Mayor [[Ken Livingstone]] proposed the [[Cross River Tram]], a new light rail system running south from [[Kings Cross, London|Kings Cross]], [[Camden Town|Camden]] and [[Euston railway station|Euston]] through Central London to [[Waterloo, London|Waterloo]], with two branches serving [[Brixton]] and Peckham.<ref>{{Cite news|date=17 August 2001|title=Tram planned for central London|language=en-GB|work=[[BBC News]]|url=http://news.bbc.co.uk/2/hi/uk_news/1496073.stm|access-date=29 March 2021}}</ref><ref>{{Cite web|date=14 May 2007|title=Cross River Tram {{!}} Transport for London|url=http://www.tfl.gov.uk/corporate/projectsandschemes/networkandservices/2043.aspx|url-status=dead|archive-url=https://web.archive.org/web/20070514003531/http://www.tfl.gov.uk/corporate/projectsandschemes/networkandservices/2043.aspx|archive-date=14 May 2007|access-date=29 March 2021|website=[[Transport for London]]}}</ref> The line would serve areas such as Walworth or Peckham not served by Underground or National Rail stations, provide fully accessible journeys thanks to [[Low-floor tram|low floor trams]], and provide faster journeys than existing bus services.<ref>{{Cite web|date=17 May 2007|title=Cross River Tram {{!}} Benefits {{!}} Transport for London|url=http://www.tfl.gov.uk/corporate/projectsandschemes/networkandservices/crossrivertram/2045.aspx|url-status=dead|archive-url=https://web.archive.org/web/20070517122809/http://www.tfl.gov.uk/corporate/projectsandschemes/networkandservices/crossrivertram/2045.aspx|archive-date=17 May 2007|access-date=29 March 2021|website=[[Transport for London]]}}</ref><ref>{{Cite web|date=12 November 2006|title=alwaystouchout.com – Cross River Tram|url=http://www.alwaystouchout.com/project/2|url-status=live|access-date=29 March 2021|website=www.alwaystouchout.com|archive-url=https://web.archive.org/web/20040407012350/http://www.alwaystouchout.com:80/project/2 |archive-date=7 April 2004 }}</ref> Consultation on the proposed tram took place in 2006–7, with the tram line proposed to open in 2016 at a cost of around £1.3bn.<ref>{{Cite web|date=22 October 2008|title=Cross River Tram: City Hall committee divided on prospects for £1.3 billion scheme [22 October 2008]|url=http://www.london-se1.co.uk/news/view/3568|url-status=live|access-date=29 March 2021|website=London SE1|language=en|archive-url=https://web.archive.org/web/20081030083159/http://www.london-se1.co.uk:80/news/view/3568 |archive-date=30 October 2008 }}</ref><ref>{{Cite web|date=20 November 2006|title=Cross River Tram Consultation Launched|url=https://www.mayorwatch.co.uk/cross-river-tram-consultation-launched/|access-date=29 March 2021|website=MayorWatch|language=en-GB}}</ref>

In May 2010, Mayor [[Boris Johnson]] published the Mayor's Transport Strategy (MTS), which outlined the Mayor's plans for public transport in the capital.<ref>{{Cite web|date=19 January 2015|title=Mayor's Transport Strategy 2010|url=https://www.london.gov.uk//what-we-do/transport/transport-publications/mayors-transport-strategy|url-status=live|access-date=31 March 2021|website=[[Greater London Authority]]|language=en-GB|archive-url=https://web.archive.org/web/20160306112001/http://www.london.gov.uk:80/what-we-do/transport/transport-publications/mayors-transport-strategy |archive-date=6 March 2016 }}</ref> The MTS specifically supported a southern extension of the Bakerloo line, noting that it would utilise spare Bakerloo line capacity, serve areas with low transport connectivity, and relieve congested National Rail lines into central London. The proposal was noted, however,  to be a long-term project, requiring further study by TfL.<ref>{{Cite web|date=May 2010|title=Mayor's Transport Strategy – Chapter five – Transport proposals|url=https://www.london.gov.uk/sites/default/files/mts_chapter_5_pt1_0.pdf|url-status=live|website=[[Greater London Authority]]|page=139|archive-url=https://web.archive.org/web/20121012222720/http://www.london.gov.uk/sites/default/files/MTS_Chapter_5_pt1_0.pdf |archive-date=12 October 2012 }}</ref>

A consultant's report for Lewisham Council in 2010 analysed the costs and benefits of a variety of different routes for a Bakerloo extension, with costs between £1.6bn and £3.6bn, depending on the destination and the route option chosen.<ref>{{cite web|author=JRC Jonathan Roberts Consulting|date=September 2010|title=Potential options for Bakerloo Line extension towards SE London|url=http://councilmeetings.lewisham.gov.uk/Data/Sustainable%20Development%20Select%20Committee/20100914/Agenda/04%20-%20%20Appendix%20B%20Bakerloo%20Line%20SE%20London%20extensions%20review%20-%20PDF.pdf|access-date=6 August 2013|publisher=Lewisham Council Sustainable Development Select Committee}}</ref><ref name=":1" /><ref name=":4" /> The report also stated that the [[Northern line extension to Battersea]] and the [[New Tube for London|Piccadilly line upgrade]] were "ahead in the investment queue", and therefore work was unlikely to begin until the 2020s.<ref name=":1" /> TfL's view was that "A key advantage of the Hayes option is that [it] releases train paths into London Bridge".<ref>{{cite web|author=London Borough of Lewisham|date=9 February 2011|title=Bakerloo Line extension: Referral from the Sustainable Development Select Committee|url=http://www.lewisham.gov.uk/mayorandcouncil/overview-scrutiny/Overview-and-Scrutiny-Reports/Documents/Bakerloo%20line%20extension%20response.pdf|access-date=6 August 2013|at=para 6.5|archive-date=10 June 2015|archive-url=https://web.archive.org/web/20150610225807/http://www.lewisham.gov.uk/mayorandcouncil/overview-scrutiny/Overview-and-Scrutiny-Reports/Documents/Bakerloo%20line%20extension%20response.pdf|url-status=dead}}</ref>

In July 2011, [[Network Rail]] published a long-term planning document for London and the South East – the [[Route Utilisation Strategy]] (RUS).

== Proposed route ==
The proposed extension of the Bakerloo line comprises 7.5&nbsp;km of twin tunnels, with 4 new stations (Burgess Park, Old Kent Road, New Cross Gate and Lewisham), 1 ventilation shaft and a depot at Wearside Road, Lewisham.<ref name=":11" /><ref name=":15" /> All stations would be fully accessible.<ref name=":11" /> The extension is estimated to cost between £4.7bn to £7.9bn (in 2017 prices), and would take around 7 years to construct.<ref name=":11" /> The route was safeguarded by the [[Department for Transport]] in 2021, protecting the alignment from development.<ref name=":16" />

=== Elephant & Castle to Lewisham ===
The route of the extension would begin between [[Lambeth North tube station|Lambeth North]] and Elephant & Castle, as a branch off the existing Bakerloo line tunnels. The new tunnels would allow for a faster and more direct route, as the end of the existing Bakerloo line tunnels point south towards Camberwell. Consequently, new platforms would have been built at '''Elephant & Castle''', underneath the Shopping Centre. The tunnels would then continue south east, generally following the [[Old Kent Road]]. '''Burgess Park''' station would be located on the site of the Old Kent Road [[Tesco]], adjacent to [[Burgess Park]]. During construction, the site would be used to launch [[tunnel boring machine]]s (TBMs) to dig the running tunnels towards Lambeth North. The line would then continue south-east underneath the Old Kent Road. '''Old Kent Road''' station would be located on the site of an existing [[Lidl]] supermarket, adjacent to Asylum Road. The line would continue south-east, along the Old Kent Road and New Cross Road. '''New Cross Gate''' station would be located on the New Cross Gate Retail Park ([[Sainsbury's]]), just west of the [[New Cross Gate railway station|existing station]]. This site would be the main construction work site of the extension, launching TBMs east and west as well as taking away the tunnelling spoil by rail, reducing the need for lorry journeys. The tunnels would continue south-east, passing beneath [[Goldsmiths' College]]. A ventilation shaft would be located between New Cross Gate and Lewisham at Alexandra Cottages. The shaft would provide ventilation for the tunnels, as well as emergency access in the unlikely event of fire/other incidents. '''Lewisham''' station would be located south-west of the [[Lewisham station|existing railway and DLR station]], on the site of the current bus station. The route would then turn south towards Wearside Road, the site of a [[Lewisham London Borough Council|Lewisham Council]] maintenance depot. Wearside Road would be used to help build the extension, as well as store and turn around trains when the extension is operational. It would also permit access to the [[Hayes line]] for a future extension to Hayes and Beckenham Junction.<ref name=":11" />

=== Future extension to Hayes and Beckenham Junction ===
Following completion of the Lewisham extension, TfL proposes extending the service over the existing National Rail line to [[Hayes railway station|Hayes]] and [[Beckenham Junction station|Beckenham Junction]], adding an additional 10 stations to the line.<ref name=":17" /> The line would have to be converted for the Bakerloo line, with TfL stating that all stations along the line would be made step-free from street to train.<ref>{{Cite web|last1=Pidgeon|first1=Caroline|last2=Khan|first2=Sadiq|date=4 November 2019|title=Bakerloo Line extension (2)|url=https://www.london.gov.uk/questions/2019/20150|access-date=2 April 2021|website=Mayor's Question Time}}</ref>

== Benefits of the extension ==
TfL, local councils and campaign groups have outlined a wide range of benefits of the extension including:<ref name=":0" /><ref name=":18" />

* Providing access to high quality [[rapid transit]] to areas of south east London with poor transport accessibility<ref name=":10" /> 
* Support the regeneration of the area, with Southwark and Lewisham Council estimating that around 25,000 new homes could be built along the corridor<ref name=":20" />
* Relieving congestion and reducing poor air quality on main roads such as the [[A2 road (England)|A2]] ([[Old Kent Road]]) and [[A20 road (England)|A20]] (Lewisham Way)<ref name=":11" />
* Reducing journey times from Lewisham to Central London by 9 minutes<ref name=":11" />
* More frequent trains than existing London Overground or National Rail services<ref name=":11" />
* Reducing overcrowding on local bus services, as well as on the Jubilee line, DLR, London Overground [[East London line]] and National Rail services into London Bridge<ref name=":11" />
* Increase the number of step-free Underground stations, making it easier for all to travel<ref name=":11" />

TfL is also planning to replace the [[London Underground 1972 Stock|current 1970s rolling stock]] on the line with the [[New Tube for London]] in the late 2020s, and install new signalling allowing for a faster and more frequent service.<ref name=":32">{{cite press release|date=15 June 2018|title=Siemens Mobility Limited to be awarded TfL contract to design and manufacture a new generation of Tube trains|url=https://tfl.gov.uk/info-for/media/press-releases/2018/june/siemens-mobility-limited-to-be-awarded-tfl-contract-to-design-and-manufacture-a-new-generation-of-tube-trains|access-date=16 June 2018|publisher=Transport for London}}</ref> This would increase capacity on the line by over 25%, as well as speeding up journey times on the existing line.<ref name=":15" />

As with the [[Northern line extension to Battersea]], TfL proposes to use their property development arm ([[Places for London]]) to [[Transit-oriented development|build on top of station sites]] when construction of the extension is completed.<ref>{{Cite web|last=Pedantic of Purley|date=7 January 2016|title=Extending the Bakerloo: It's not about Transport|url=https://www.londonreconnections.com/2016/extending-bakerloo-not-transport/|url-status=live|access-date=2 April 2021|website=London Reconnections|archive-url=https://web.archive.org/web/20160110100159/http://www.londonreconnections.com:80/2016/extending-bakerloo-not-transport/ |archive-date=10 January 2016 }}</ref><ref name=":11" /> This would recoup some of the costs of building the extension, as well as providing long term income for TfL.<ref>{{Cite web |title=Property|url=https://www.tfl.gov.uk/info-for/business-and-commercial/property-development|access-date=2 April 2021|website=Transport for London }}</ref>

== Perspectives ==
The line is supported by major political parties, local councils and property developers along the route.<ref name=":15" /><ref name=":19" /> Bromley Council are supportive of the extension to Lewisham, but do not support a further extension to Hayes and Beckenham Junction.<ref name=":21" />

Several businesses that would have to relocate if the extension was built do not support the extension.<ref name=":15" /> Tesco and Sainsbury's – both of which have supermarkets currently located on proposed station sites – have stated that they support the extension, but do not support the loss of their stores due to construction.<ref name=":15" /><ref name=":14" />
