Safety concerns mean train lines between Surbiton and Weybridge are blocked while inspectors examine the track.

South West Train services may be delayed by up to 15 minutes or run nonstop between the stations.

Trains towards Woking are unable to call at Esher, Hersham and Walton. 

Anyone wanting these stations is advised to take a train to Weybridge and get a London bound service back. 

The inspection follows delays this morning caused by a broken down train between Weybridge and Surbiton.

The disruption is expected until at least 11.30am.
