A MAJOR fault with Network Rail signalling systems is causing disruption for rail passengers this morning.

Trains between Woking and Surbiton are unable to run to Waterloo.

This includes the Weymouth and Bournemouth route to London Waterloo and the Salisbury to Waterloo mainline.

Disruption is expected until at least 4pm.

A spokesperson for South Western Railway said: "We are advising all passengers who travel on the mainline, and suburban services that run through these stations, not to travel and to check southwesternrailway.com for updates.

"Network Rail engineers have been on site through the morning and are working to resolve the issue as quickly as possible."
