Teddington station will be made more accessible for people with limited mobility, heavy luggage or children in prams thanks to a portion of a £60m Government fund.
Teddington is one of 26 stations across England to benefit from the Access for All funding, announced as part of the autumn statement.
The upgrade work, which will likely see a lift installed, is set for completion by 2019, and will make a huge difference according to MP for Twickenham Vince Cable.
He said: "Teddington is a major local station acting as an interchange between a number of different routes but many passengers have been unable to make use of that interchange because the only route between platforms was over the footbridge."
Brian Holder, leader of the Teddington Society roads and transport group, said although the upgrade was long overdue it would be a very welcome improvement that will help a huge amount of people who otherwise would have a lengthy walk to cross platforms.
Teddington ward councillor Martin Elengorn said: "With the recent Grade II listing of the station, the celebration of its 150th anniversary and now its improved accessibility, our much-loved station has received the care and attention it so richly deserves."
