Chessington South station flooded this morning after rainfall during the night.
Wooden pallets have been put down for commuters to walk over the water in the underpass between platforms.
Buffalou asked South West Trains: "When are you going to sort out flooding problem at Chessington Sth?
"Walking on slippery wet wooden pallets isn't ideal."
South West Trains replied: "Thankyou for the photos. We've been in contact with the station staff who are working to resolve this."
Flooding also affected the A3 this morning at the underpass at Tolworth.
