South West Train delays: Commuters describe 'meltdown' as signalling problems spark rail chaos

London commuters are facing rail chaos this evening after a signalling fault sparked a raft of delayed and cancelled services.

South West Trains warned passengers face severe disruption because of signal problems at Barnes.

Lines have been blocked affecting trains travelling between Clapham Junction and Richmond or Chiswick, which has caused delays to journeys across the capital.

Travellers took to Twitter to describe “chaos” on the railways.

One woman tweeted: “Absolute nightmare of a journey! No @SW_Trains to Putney from Waterloo and no one to say when the train will actually move.”

Fran Perrow ‏wrote: "Meltdown at Waterloo - all lines blocked through Barnes @SW_Trains."

Matt Nixon wrote: “It's chaos as usual at Waterloo w no info and cancelled trains. Please tell us more so we can act accordingly."

While Ioan Williams added: “Nothing moving at waterloo.”

South West Trains said the disruption was likely to last until 8pm.
