Editing Bakerloo line (section)

===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>
