Trains from London Waterloo to the commuter belt in Surrey and beyond could be delayed or cancelled until 8pm due to signalling problems.

The disruption, on lines between Waterloo and Basingstoke, Aldershot and Dorking is down to a signalling problem between Waterloo and Wimbledon.

Operator South West Trains have warned of delays of at least 10 minutes potential alterations to all services until at least 8pm.

Commuters are stuck at Wimbledon, where many routes converge.
