Editing Jubilee line (section)

=== Proposed extensions ===
The Jubilee line of 1979 was to be the first of four phases of the project, but lack of funds meant that no further progress was made until the late 1990s.

* Phase 2 would have extended the line along [[Fleet Street]] to stations at [[Aldwych tube station|Aldwych]], [[Ludgate Circus]], [[Cannon Street station|Cannon Street]] and Fenchurch Street. Parliamentary approval for this phase was granted on 27 July 1971.<ref name=Horne_36>{{cite book | first=Mike |last=Horne |title=The Jubilee Line |year=2000 |publisher=Capital Transport |isbn=978-1-85414-220-7 |page=36}}</ref>
* Phase 3 would have seen the line continue under the river to Surrey Docks (now [[Surrey Quays]]) station on the [[Windrush line]], taking over both of the ELL's branches to {{rws|New Cross Gate}} and {{rws|New Cross}} stations, with an extension to Lewisham. Parliamentary approval for this phase as far as New Cross was granted on 5 August 1971 and the final section to Lewisham was granted approval on 9 August 1972.<ref name=Horne_36/>
* In 1973, an alternative plan for Phase 3 was devised to provide transport connections to the London Docklands area then being considered for regeneration as it was expected that the docks would be closed by the late 1980s. Initially proposed as a mainline service but later developed as a tube line extension for the Jubilee line, the new plan was developed over the next few years to a final form that considered extending the line parallel to the River Thames known informally as the 'River line'. This would have taken the line from Fenchurch Street to [[Thamesmead]] via [[St Katharine Docks tube station|St Katharine Docks]], [[Wapping railway station|Wapping]], [[Surrey Docks North tube station|Surrey Docks North]], [[Millwall tube station|Millwall]] (near the later location of [[South Quay DLR station]]), [[North Greenwich tube station|North Greenwich]], [[Custom House for ExCeL DLR station|Custom House]], [[Silvertown railway station|Silvertown]], [[Woolwich Arsenal station|Woolwich Arsenal]], and then to Thamesmead Central. The depot would have been at [[Beckton tube station|Beckton]], roughly on the site of the current Docklands Light Railway depot, and a shuttle service between there and Custom House was considered. Parliamentary approval for the route as far as Woolwich Arsenal including the Beckton branch was granted on 1 August 1980.<ref name=Horne_50>{{cite book | first=Mike |last=Horne |title=The Jubilee Line |year=2000 |publisher=Capital Transport |isbn=978-1-85414-220-7 |pages=50–52}}</ref>
* Phase 4 was the possible continuation of the original Phase 3 Lewisham branch to take over suburban services on the [[Addiscombe Line|Addiscombe]] and [[Hayes Line|Hayes]] branches.
