SOUTHAMPTON'S London-bound commuters are facing major delays this morning after a signalling issues at Waterloo.

Bosses at South Western Railway are warning of cancellations, delays and revised timetables on all services to and from the station.

The railway company say the station is currently experiencing problems with track circuits at London Waterloo.

As a result, fewer trains are able to run.

It follows signalling problems on the line between Surbiton and Clapham Junction – which have since been fixed.

The disruption is expected to last until 10am today.

A spokesperson for South Western Railway said: "Our control centre has received reports of a track circuit failure at London Waterloo, meaning that trains have to run at reduced speed in the area. A track circuit is the method that our signallers use in order to detect the presence of trains on the track.

"Until this is rectified one of our lines into London Waterloo is blocked and less trains are able to run.

"Services will therefore be delayed, and some may be subject to short notice alterations.

"Until further notice all trains from the West of England line (from Exeter, Salisbury) will terminate and start from Basingstoke.

"For further information, please speak to a member of staff or use a help point, and please keep checking for updates.

"We are sorry for any disruption this may cause to your journey this morning."
