A public consultation is being launched over the proposed route for London's new rail link, Crossrail 2.
There's two routes to choose from - the Metro scheme and Regional scheme - which could half journey times for some commuters.
The Metro scheme would go from Wimbledon to Alexandra Palace, mostly underground, stopping at Clapham Junction, Victoria and Euston.
The Regional scheme would take in the same central Wimbledon to Alexandra Palace route, but would stretch south west of Wimbledon into Surbiton and Kingston.
The consultation will be opened by Boris Johnson at Wimbledon Station this morning and will run until August 2.
