Londoners have been invited to consult on plans for a proposed new London Overground service linking communities in the west of the capital.
TfL are running the eight-week consultation until November 18 to invite feedback regarding a potential 18.5km West London Orbital, which would connect communities in north and northwest London.
The route would use rail lines which are currently only used for freight, but TfL hope the route could improve access to major transport hubs including Old Oak Common, and support new jobs and homes.
Plans include up to six trains per hour linking areas such as Brent Cross, Neasden, Harlesden, Acton, Brentford and Hounslow,
Access to London Underground, London Overground, National Rail, the Elizabeth line and HS2 would also be improved.
TfL believes that the scheme could remove around 650,000 car journeys a year across the capital.
Subject to funding and approvals, 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.
From Hounslow to Hendon, without the detour.

David Rowe, TfL’s Director of Investment Planning, said: "This consultation is an important opportunity for people to shape the future of this new London Overground route. By making better use of existing rail infrastructure, we can improve connections between communities and support growth across west and northwest London.
"We want to ensure that everyone understands the proposals and has the opportunity to share their views. All feedback will be carefully considered as we continue to develop the scheme with our partners."
Seb Dance, Deputy Mayor of London for Transport, said: "The Mayor and I are delighted that TfL is taking this important first step in proposals to add a brand-new line to the London Overground network, utilising a line currently only used for freight to transform travel in north and northwest London.
"As well as connecting communities and improving access to vital places like schools, hospitals and transport hubs, this innovative rail project means we can drive regeneration and growth not only along the new route but across our great city – unlocking homes, jobs and opportunities.
"The Mayor and I encourage Londoners to have their say in the consultation and help shape this exciting new transport connection as we continue building a better, greener, more prosperous London for everyone."
