Bakerloo line extension over the coming years. During 2005–06, TfL commissioned a transport strategic report for London, "Transport 2025: transport challenges for a growing city". Transport commentators have reported that this publication had recommended a Bakerloo extension as the most beneficial option for extending the Tube in South London, and that it considered three route options for the Bakerloo line; from Elephant & Castle, the proposed routes were either south to Camberwell and Streatham, or east to Beckenham and Hayes: Option 1: via Burgess Park, east to and ,with the option of taking over the Hayes Line to terminate at Option 2: south
Finchley Road tube station west London, caused by the limited capacity of its tracks between Finchley Road and Baker Street stations. To alleviate this congestion new sections of deep tube tunnels were bored between Finchley Road and Baker Street to carry some of the traffic from the Stanmore branch and stations south of Wembley Park. These new tunnels opened on 20 November 1939 and from that date Finchley Road station was also served by Bakerloo line trains running from Baker Street using the new tunnels. The Bakerloo line services were subsequently transferred to the Jubilee line when that line commenced operation on 1 May
