Train operator First Great Western is imposing restrictions on the number of bicycles which can be carried on its trains in the Thames Valley this weekend.

The rules have been put in place because the Prudential Ride London cycling festival is taking place in the capital, along with a race in Surrey on Sunday.

Only folding bicycles will be allowed on services operated by Turbo diesel trains and bike reservations will be compulsory on High Speed Trains operating expresses calling at Oxford, Didcot Parkway and stations on the Cotswold Line.
