People travelling into London this evening are being warned of long delays because of a signalling problem at Waterloo.
Trains running towards the capital may terminate at Basingstoke, Guildford and Woking with delays of up to an hour.
It's expected to continue for the rest of the night.
A major upgrade of signalling equipment at Ashford International Station will go ahead following news that the European Commission will co-fund half of the £4 million project.
The investment will secure the town's place on the international rail map and create thousands of jobs for local people.
