A plan to extend Crossrail 2 out beyond the M25 to Woking and Guildford is being examined by Surrey County Council.
The local authority announced a study into the feasibility of lengthening the much hyped cross-London rail line.
The government earlier this year announced plans to safeguard from development a core route for Crossrail 2 from Wimbledon in south-west London to Tottenham Hale and New Southgate in the capital’s north-east.
Regional extensions have been mooted as far as Cheshunt in Hertfordshire and Surbiton and Epsom in Surrey.
But Surrey County Council believes taking the line further out to the commuter belt could boost the local and regional economy as well as freeing up space on the South West Main Line into Waterloo.
Transport cabinet member Mike Goodman explained the proposal in greater detail in this video.
London mayor Boris Johnson this week put former local government chief Sir Merrick Cockell in charge of maximising the benefits of Crossrail 2.
