Commuters have been faced with chaos trying to get to work with London Waterloo suffering four blocked platforms because of emergency engineering works.
All trains between London Waterloo to Chessingon South and Dorking have currently been cancelled.
The delays are expected to last until 3pm.

He said: “08.27 from #Cobham to #Waterloo now on the move with 30 mins delay. Missed meetings – huge cost to businesses @swtrains_watch @SW_Trains.”
Robert Perry tweeted: “Avoiding any disruption at London Waterloo by working from home.”
Matt Hill tweeted: “Why is it that whenever I need to go to London for important stuff, there is always disruption with @SW_Trains.”
