A number of huge transport projects are currently underway or are being planned in London.
Transport for London (TfL)’s pipeline of projects include the creation of major new transport links, large upgrades to existing services, and major bus and road programmes.
While many of the schemes are being actively developed, some are in the early planning stages, and do not yet have construction funding.
Here are all of the projects being planned in the capital.
The proposed new London Overground route would run between Hendon and Hounslow, and would improve access to major transport hubs as well as supporting new jobs and homes.
Plans include up to six trains per hour, while four new stations – Neasden, Harlesden, Old Oak Common Lane, and Lionel Road – have been proposed, along with additional infrastructure at existing stations.

TfL believes that the scheme could remove around 650,000 car journeys a year across the capital.
The new route could support the delivery of around 25,000 homes, 11,500 jobs and up to £1.3 billion in wider economic benefits.
A funding package of up to £6.65m to support the next phase of design, modelling and public consultation work was agreed earlier this year, and a decision on whether to seek powers to build the scheme will be made in 2027.
TfL has said that construction could begin in the early 2030s, and the service could potentially start around 2035, subject to funding and approvals.
DLR extension to Thamesmead
TfL is also working on a proposed extension of the Docklands Light Railway (DLR) to Thamesmead in order to serve the Beckton Riverside and Thamesmead redevelopment areas in east London.
TfL has said that the project could support up to 25,000 homes and 10,000 jobs.

The HM Treasury gave approval in the November 2025 budget for TfL and the Greater London Authority (GLA) to be loaned money to build the extension.
TfL is preparing a Transport and Works Act application, with construction potentially beginning around 2029 and opening in the early 2030s, subject to funding and approvals.
The project, which is estimated to cost around £1.6 billion, could start construction in 2029, with the extension to open in the early 2030s.
Under TfL proposals, a Bakerloo line extension to Lewisham – and potentially beyond – could unlock thousands of new jobs and homes along the route.
The primary extension, which could also see 27 Bakerloo line trains run per hour, would include additional stations at Old Kent Road and New Cross Gate.
The line’s ageing fleet would be replaced with modern trains, significantly improving service quality.

A potential second phase of the extension could see the line stretch from Lewisham through Catford, Sydenham, Beckenham and Hayes.
The latter phase would involve taking over the existing National Rail route.
A public consultation on the scheme has been scheduled by TfL for between December 2026 and February 2027.
When proposed in 2010, Phase 1 was expected to open by December 2026 – however HS2 services from Old Oak Common in west London to Birmingham are currently scheduled to open between May 2036 and October 2039.

The full extension to London Euston is then expected between 2040 and 2043.
The high-speed railway has been under construction since 2020.
Crossrail 2, a proposed major line designed to link national rail networks in Surrey and Hertfordshire via a new underground tunnel through central London, is currently on hold.
The proposed route would run from Wimbledon in the southwest, through Chelsea and central London, to Tottenham Hale and New Southgate in the northeast.
The new line would also connect directly with stations including Victoria, London Euston and St Pancras, providing direct access to the HS2 and the Eurostar services.
TfL paused design and development work in 2020, and is currently maintaining the safeguarded route rather than actively progressing it towards construction.
There is no current timetable for the project to restart.
Great Northern rail devolution
TfL is seeking to take control of Great Northern inner suburban rail services, with the plan to integrate them into the London Overground network.
The proposed devolution would bring services from Moorgate to Welwyn Garden City and Stevenage under the control of the Overground.
TfL and the Mayor of London have targeted a handover by December 2027, with the aim to increase off-peak frequencies up to six trains per hour on the Hertford Loop.
A business case has been submitted to the government, which says it could use its own operating budget to take over the route, while subsequently improving fares and ticketing, stations and customer information.

The fleet will have air conditioning and walk-through carriages, along with wider doors and improved accessibility.
There will be enhanced digital display screens for customer information, improved step-free access from/onto the platform, and on-train CCTV cameras for additional customer security.
Once the new fleet is fully introduced, peak service should rise from 24 to 27 trains per hour, with potential for further increases following future signalling investment.
TfL is also expanding Superloop, the capital’s orbital express bus network.

Since its launch in July 2023, the Superloop network has accommodated around 81 million trips.
