Passengers are still facing long delays on the main route between Reading and Oxford due to a power failure in the Swindon area. ITV News journalist, Guy Phillips, is one of those affected. He's just sent us this update from his train stuck at Didcot.
"We're being told that we will have to wait here 'for a while' due to a big back log of trains. The power cut is affecting signalling." He will send another updates as soon as he's on the move or gets more information.
