Fears that fast trains into central London from Surbiton could be lost are mounting as worried commuters take umbrage with the lack of absolute guarantee over continued service levels within Crossrail 2 plans.

Under proposals for the high speed rail network, the line would cut through New Malden, Berrylands, Surbiton, Kingston, Norbiton, Tolworth and Chessington stations.

It has been said it could create 200,000 new homes and 200,000 jobs.

But those who value existing quick services to London Waterloo are feeling the jitters.

Commuter John Biltcliffe said: “While I strongly support the additional capacity and concepts of Crossrail 2, the current services are stretched beyond capacity as can be shown by the amount of delays a minor issue can cause.

“Many of the commuters will have taken jobs, bought homes and planned their lives around the existing train services.”

If fast train service levels were changed these would have a big impact on large numbers of people across the borough, he added.

St Mark’s Councillor Liz Green, leader of the Liberal Democrat opposition, has said she was told by Crossrail 2 representatives at a consultation event that there could be no guarantee of fast trains from Surbiton to Waterloo in plans for Crossrail 2.

She said while she is supportive of Crossrail 2 in the borough the promise of a similar service is "not necesarily good enough" as people have moved specifically to Surbiton for the fast links to central London.

Adding: "If that train becomes less of a fast train then some people will say 'I could've got more for my money in Tolworth'."

Consultation documents state: “Surbiton would also retain fast and semi-fast services into Waterloo.

“These would operate to at least the current service levels, with the potential to increase the frequency to take advantage of the capacity released by Crossrail 2 services at Waterloo.”

A Network Rail spokesman refused to expand on whether this meant existing fast services would be reduced from the station.

A Crossrail 2 spokesman told worried Kingston Council Liberal Democrats on Twitter that fast services through Surbiton would be protected and there were no intentions to cut these, but admitted they could not “make guarantees for 15 years’ time”.

Kingston and Surbiton MP James Berry, who uses the fast services from Surbiton, said: “I can understand why Crossrail 2 cannot give any firm commitments on anything when the project is subject to consultation many years away from delivery.

“I will be responding to the consultation. If the local Lib Dems have any suggestions, they can also respond to the consultation as I know many residents will be.”

Liberal Democrats staged a “fightback” at Surbiton station on the morning of November 26, to inform commuters about what they fear could happen, and have set up a petition to keep the “Surbiton Express” and stop Slowbiton becoming a reality.

New Malden resident Liz Meerabeau said of stopping trains: “Would it really hurt the residents of Surbiton to share a bit, adding a few minutes to their journey to give less favoured parts of the borough better connectivity?”

Kingston Council leader Kevin Davis said: “Crossrail 2 is not due to be completed for 15 years and we know that the overcrowding on trains to London is already terrible.

“Whatever service we get, the increase in trains from all stations in the borough has to be welcome. No one can guarantee where individual trains will stop this far out from implementation so let us be pleased that new infrastructure is coming and get concerned about the micro-detail when the plans are more developed.”

The next Crossrail consultation event in the borough will be today at Chessington Sport Centre, Garrison Lane, Chessington, Saturday, December 5, from noon to 8pm.
