A good service is operating on the majority of routes across South West Trains network, the company say, however trains are running on an amended timetable on suburban lines due to a signalling problem at Waterloo.
As a result, trains are not currently able to use platforms 1 and 2 at the station, affecting services to and from Epsom/Dorking and Hampton Court.
However, there remains a good service on all other routes.
Emergency engineering work will be carried out overnight to repair the signalling fault. As a result, passengers are advised that an amended timetable will remain in place for the rest of the day.
A signalling problem at Clapham Junction is the cause of the delays for commuters this morning. Travellers should expect delays of up to 30 minutes to and from London Waterloo. Delays expected until around midday. Visit National Rail for more info on how services are running.
