TfL sets aside £20bn for six line extensions

Tube 1209419 960 720

Transport for London (TfL) has set aside £19.6bn to build six line extensions across its Underground, Overground and tram networks by 2038.

The figure was revealed in papers published ahead of a board meeting later this month. No funding breakdown for each project is given.

Projects include the Bakerloo line extension to Lewisham, the Northern line extension to Battersea and a £1.5bn extension of the Elizabeth line to Ebbsfleet. There is also a plan to extend the Docklands Light Railway to Thamesmead, the London Trams network to Sutton and the Overground to Barking Riverside.

Although the funding has been set aside for the extensions, the report said that due to their size, complexity and expense, they would require bespoke funding and delivery plans, as was the case for Crossrail 1 and the Northern line extension.

The papers say funding for these projects come from central government investment grant, developer contributions and other forms of land value capture.

Elements of some projects are expected to be delivered by bodies other than TfL, including Network Rail.

The funding allocation for the Elizabeth line extension to Ebbsfleet will give fresh hope to the possibility of the project going ahead after TfL commissioner Mike Brown said in January this year that the project was “not on the agenda”.

Interest in extending the Bakerloo line also seems to be increasing. New Civil Engineer understands TfL has recently been in touch with contractors and consultants to see how the line could be built on a tight budget.

This comes on the back of a public consultation in September last year when TfL said there was “strong support shown for the extension beyond Elephant & Castle”.

The extension includes two new Underground stations on Old Kent Road and a stop at New Cross Gate.

Under the new plans, work on the extension would begin in 2023 subject to funding. The estimated cost of the six-year project is £3.1bn.

In December last year, a Morgan Sindall Construction & Infrastructure and VolkerFitzpatrick (MSVF) joint venture (JV) was appointed to build the 4.5km long Barking Riverside rail extension. Construction is due to start on site in April and be completed in 2021.

  • This may all seem "fine and dandy" but, speaking as someone who was born in Kent and now lives in Surrey, do we not need to sort out the railways in the North of England first?

  • Wouldn't it be easier to just better integrate the existing Ebbsfleet HS line to St.Pancras at Stratford International to the Elizabeth Line at Stratford. This is a short 'missing link' which would cost half a million, not £15 billion.

  • This isn't really news. Northern Line extension is under construction and nearly built. Bakerloo line extension is undergoing planning. Contract for Barking Riverside London Overground extension has already been let. Sutton tramlink extension has been going through feasibility for the last year. This seems to be talking a lot about projects that are already underway?

  • TfL should add a brand new tube line to their list of future projects: the "Albert Line".

    This new line would link Clapham Junction to Finsbury Park via Chelsea, South Kensington, Royal Albert Hall, Lancaster Gate/Paddington, Maida Vale, Finchley Road, Belsize Park, Gospel Oak and Archway.
