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 The last 1938 stock train was withdrawn on 20 November 1985.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>
