Fleet Line
From its inception, construction of the Fleet Line was to be split into stages to spread out the funding requirements, as had been done on the Victoria Line:
- Stage I – Stanmore to Charing Cross
- Stage II – Charing Cross to Fenchurch Street
- Stage III – Fenchurch St to Lewisham, boring tunnels under the Thames; or
- Stage III and IV – Fenchurch Street to Thamesmead
1969 Parliamentary approval for stage 1
Docklands became a site for major redevelopment
1971 Stage III of the original line was given Royal Assent for an extension to New Cross. The Stage III plan was changed to reach Wapping by taking over the East London Line’s Thames Tunnel, which would save the cost of boring a new tunnel under the Thames but would involve lengthening platforms on existing stations
1971 Baker Street was modified; the Stanmore branch of the Bakerloo Line was joined to a new 4km tunnel to Bond Street, Green Park, and Charing Cross.
1974 A Docklands-focused option for the line became more of interest instead of the line to Lewisham
1977 The Fleet Line was renamed the Jubilee Line
1979 Passenger service began. The extension of the Line eastwards was settled as following the lines of the 1976 River Line proposal from the Docklands Strategic Plan.
