Train services between London Paddington and Reading have resumed after over-running engineering work led to line closures in both directions this morning.
But service disruption is expected to continue until the early hours of tomorrow morning, with First Great Western warning passengers trains may be cancelled or delayed by up to 90 minutes.
Tickets dated for travel today will be accepted this afternoon and tomorrow, and arrangements have been made for First Great Western tickets to be accepted by other operators.
