Jubilee line
The Jubilee line is a London Underground line which runs between Stratford in East London and Stanmore in North West London. First identified as a separate line in 1979, the Jubilee line is one of the newest line identities on the Tube network, although parts of its alignment date back to sections of the original Metropolitan Railway extensions north of Baker Street.
Metropolitan Railway era
The first parts of what is now the Jubilee line opened in phases as the Metropolitan Railway extended its route north from Baker Street through to Willesden Green and then on to Wembley Park and Harrow-on-the-Hill. In 1932 the Metropolitan Railway opened its final section of track as an independent railway in the form of a branch to Stanmore,[1] which would after 1939 form the Northern end of the Bakerloo line Stanmore branch and subsequently the Northern terminus of the Jubilee line from 1979.
Bakerloo line era
In 1933 the London Passenger Transport Board (LPTB) was formed as the organisation responsible for managing the majority of public transport in London. Following its formation the LPTB carried out works to divert the Metropolitan line's local services south of Wembley Park as well as the Stanmore branch onto the Bakerloo line, in order to aliviate congestion on the section of line between Finchly Road and Baker Street.[2] This work saw the creation of a new section of tube tunnel between Baker Street and Finchley Road stations as well as the realignment of the lines between Finchley Road and Wembley Park to move the local lines to run between the fast Metrpolitan line tracks instead of next to them, work was also conducted at this time to build a new burrowing junction north of Wembley Park to seperate trains to Stanmore. Bakerloo line trains began running from Baker Street to Stanmore from November 1939.[3]
Jubilee Line
While the transfer of the local services between Stanmore and Baker Street helped the Metropolitan lines' congestion issues it created new congestion issues for the Bakerloo line with limited terminating capacity at Elephant & Castle and reduced services to Queens Park plans soon emerged for a new line to relieve the Bakerloo line. In 1971 work began on the construction on this new line, named provisionally as the Fleet line with new tunnels between Baker Street and Charring Cross calling at Bond Street and Green Park.[4]
