TRAIN services to Dorset have been disrupted by a trespasser on the line at Clapham Junction this morning.

South West Trains confirmed that although the incident had been dealt with, there would be delays of up to 30 minutes on services until 3pm.

Trains to Dorset were also affected by a lineside fire in the Swaythling area of Southampton.

In a statement the company said: "An earlier trespass incident at Clapham Junction means that services were unable to operate through the area.

"The issue has now been dealt with however throughout the morning additional incidents of a collapsed passenger at Wimbledon and lineside fire between Swaythling and Southampton Airport Parkway have affected our ability to recover the service back to its normal schedule.

"Be assured that our teams are working as quickly as possible to return services back to normal.

"There will be residual delays and alterations whilst we return the service to normal."

CrossCountry services have also been affected.
