Rail services across the Thames Valley are today in chaos because of flooding hitting hundreds of thousands of passengers. By 6.30am, even before the busy rush hour got underway, more than 20 services from Reading, Oxford and Newbury had been cancelled.
First Great Western say they can't say how long the problems will last.
Only four of the usual twenty five trains an hour are running into Paddington.
Reading is by far the most badly hit but the lines to Oxford and Newbury also have very few services.
The problems are at Maidenhead where two of the four tracks can not be used and between Didcot and Oxford. This is on top of line closures in the West Country.
Passengers are advised to use Chiltern or South West Trains where possible.
