47583 County of Hertfordshire passes Didcot North Junction on 22 June 1989 with the 5F60 18:53 Maidenhead to Oxford Carriage Sidings ECS. This was a direct continuation of the 1F60 18:20 Paddington to Maidenhead Network SouthEast service. It does seem odd that over half the train's journey from London to Oxford should be empty stock, when surely at that time of the evening there would plenty of demand for a through passenger service.
