A major signalling fault is affecting services on the South Western Main Line with South Western Railway advising passengers not to travel and to seek alternative arrangements.
There is a major signalling failure which is affecting all lines between Woking and Surbiton, meaning trains are unable to run on this line through to London Waterloo. Trains between Salisbury and London Waterloo will start and terminate at Basingstoke.
Network Rail engineers are on site and are working to resolve the issue as quickly as possible.
Network Rail is urging passengers to follow the travel advice issued by South Western Railway which is that all passengers who travel on the Main Line, and suburban services that run through these stations, should not travel and should check southwesternrailway.com or National Rail Enquiries for updates.
Network Rail would like to apologise for the disruption this morning and thanks passengers for their continued patience whilst we work to resolve this issue.
