Trains from Guildford to London Waterloo are being delayed after an incident involving trespassers near Surbiton.

The tracks have been cleared but 15-minute delays are expected to continue until 11am.

South West Trains added: "A trespasser on the line between Surbiton and Effingham Junction means that trains are unable to run in this area.

"Our teams are en-route to remove the trespasser and our aim is to resume train services as soon as possible.

"Until the trespasser has been removed trains through this area will be cancelled or diverted via Woking or Epsom at short notice."
