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>

=== Former rolling stock ===

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>
