Train services between Oxford and London Paddington are unable to run east of Reading at present, due to a fire close to the line in London.
Train operator First Great Western has been forced to suspend services on the advice of the London Fire Brigade, which is tackling a blaze at Hanwell, in West London.
A shuttle train service will run between Reading and Hayes & Harlington station, west of Hanwell, until further notice.
FGW tickets are also being accepted on South West Trains services between Reading and London Waterloo and on Chiltern Railways services between Oxfordshire stations and London Marylebone.
For the latest information, see the FGW website or call 08457 484950.
