TfL has finally set a firm timeline and price tag for extending the Docklands Light Railway (DLR) into long-overlooked Thamesmead and Beckton, promising a game-changer for southeast London commuters.
New DLR Route and stations
The extension stretches from Gallions Reach – the current eastern terminus near London City Airport to Beckton Riverside and Thamesmead, adding two shiny new stations along the way.
A key highlight is a 1.5km tunnel burrowing under the River Thames to connect Beckton Riverside and Thamesmead, complete with a turnback siding for future service boosts. This setup will deliver trains every 8-10 minutes once open, slashing travel times dramatically.
When will the DLR extension construction start and finish?
Construction kicks off with early enabling works in 2027, ramping up fully in 2028, and wrapping by the end of 2033 – a seven-year effort to transform the line.
Plans have evolved since 2010, with initial hopes for a 2026 finish pushed back amid consultations and budget tweaks. Public backing was strong during TfL’s 2024 consultation, paving the way for this tender release in February 2026.
How much will the DLR extension cost?
The project carries a hefty £1.62 billion price tag, mostly funded through borrowing by TfL and the Greater London Authority (GLA).
Government support came via the 2025 Autumn Budget under Chancellor Rachel Reeves, green-lighting the scheme without a direct cash injection – it’s more of a borrowing nod. Mayor Sadiq Khan hailed it as a “win-win” for unlocking growth, though exact central funding remains TBD.
Boost for homes and jobs
This extension could unlock 25,000 new homes, including potential “new town” developments at Thamesmead Waterfront, plus up to 10,000 jobs.
Commuters stand to win big: City of London trips drop from an hour to 35-40 minutes, Stratford in 25, and London Bridge in 30.
It’s a lifeline for an “historically under-served” area, spurring £18 billion in private investment.
New DLR trains update
New B23 trains rolled out last September but hit a snag with a braking issue, leading to a temporary withdrawal. They’re slated to return by late 2026, just in time to prep for the extension buzz.
