Further delays hit the trains between Hampden Park and Eastbourne this afternoon (9 August).
A trespasser was reported to be on the tracks between the two stations at around 4pm, prompting power to be cut to the tracks whilst police dealt with the matter.
As a result, delays of up to 45 minutes, cancellations and short notice alterations were made to services by Southern. Power was restored to the tracks around 5.20pm and the lines were reopened.
Southern say they are still experiencing residual delays as a result of the disruption.
