Three out of the five platforms at Waterloo's disused international rail terminal could be back in use by domestic train services by the end of this year.
The five platforms under Nicholas Grimshaw's serpentine blue roof have been disused since the last Eurostar train left Waterloo in 2007.
South West Trains has already begun to make occasional use of platform 20 at Waterloo International and it will be in regular use from May this year.
Now the rail company has revealed that proposals are being developed to re-open platforms 21 and 22 later this year, whilst a longer term solution is agreed with the Department for Transport.
"Great progress is now being made with the Department for Transport to redesign Waterloo and the surrounding area which could enable us to introduce more additional trains and provide some of the biggest improvements at Waterloo since the 1930s," said Tim Shoveller, managing director of the South West Trains-Network Rail Alliance.
