Transport for LondonNext steps
We would expect the entire process to take 5-7 years
Once they grant approval for us to request planning permission (via a Transport and Works Act Order Application), a full programme of public consultation would then be embarked upon. When the consultation process has finished, the application would be submitted.
The project would then require final financial approval and construction would then follow. The entire process would be expected to take 5-7 years.
Works programme
The proposal would divert the existing Watford branch of the Metropolitan line to Watford Junction station via a disused National Rail line. It would involve the following works:
The proposed new viaduct
- Two new Tube stations at Ascot Road and Watford West
- A new viaduct to link the existing Metropolitan line at Croxley to the disused Network Rail Croxley Green Branch line
- Double tracking of the Croxley Green Branch line which is currently single track
- Refurbishment of platforms and stations at Watford High Street and Watford Junction
- Possible closure of the Metropolitan line station at Watford and of the branch north of the viaduct
