A signal fault sparked major delays for commuters on the way into Waterloo this morning.
Operator South Western Railway warned passengers to expect “major disruption” until 2pm following a signalling problem between Putney and Barnes in south west London.
Services face delays of up to 30 minutes as well as cancellations. The signal fault has been repaired.
Twitter user Gary Palmer posted: "No trains again @SW_Help to Waterloo! I make that now 22 times since 1st August when my trains have been delayed or cancelled.”
South Western Railway said in a statement to passengers that trains running through Putney to Barnes were cancelled, diverted or revised.
They apologised and said the disruption.
