There are still major delays on South West Trains tonight after a signalling problem this lunchtime.
Mainline services between London and the south coast are being delayed by up to an hour. Some suburban services have been cancelled entirely.
A statement on the company's website says:
"Owing to an earlier major signalling problem in the Clapham Area, lines to/from Waterloo are open again but services across the entire South West Trains network may be subject to disruption, owing to the amount of time the lines were previously closed for.
"Disruption is expected until end of service 12/10.......We are sorry for the inconvenience caused to your journey today. "
