Trains are expected to be delayed through peak hour tonight due to a trespasser on the tracks.
Earlier today South Western Railway were made aware of a trespasser on the line between Worcester Park and Stoneleigh.
As a result, all lines had to be temporarily blocked whilst the power was switched off and the trespasser removed.
During this time, no trains could travel in either direction.
BTP have now attended the scene and removed the trespasser.
Lines have now reopened and trains are on the move however, trains may still be delayed or revised at short notice.
Apart from the Sutton area, trains between Raynes Park and Epsom may also be delayed or revised.
These delays are expected to continue until at least 9pm tonight.
