47716 Duke of Edinburgh's Award arrives at Oxford on 18 July 1990 with the 5F50 18:43 Twyford to Oxford ECS. This was the continuation of the 1F50 17:53 Paddington to Twyford Network SouthEast service, but why it was booked to run the rest of the way as empty stock, during the evening peak, is a bit of a mystery.
