Flooding and damage caused by the extreme weather is causing major disruption on parts of the rail network causing travel misery for many commuters at the start of the working week.
National Rail said the River Thames had flooded at several locations between Staines and Windsor & Eton Riverside stations early on Monday. Trains in the area are cancelled and replacement buses are "not available".
The main rail route into Devon and Cornwall via Bridgwater remains cut off by problems caused by flooding and storm damage.
Robin Gisby from Network Rail told the BBC: "It is going to be a struggle for passengers."
