The driver and train manager went to Banbury in Oxfordshire where they were due to take control of the service to London Paddington.
But instead they got on the train heading to Swansea and set off toward South Wales.
The First Great Western crew realised their mistake a short distance down the line and decided to head back to Banbury to get the right train.
