47603 County of Somerset passes Chilson on 28 June 1986 with the 1A25 08:00 Hereford to Paddington service. Note the inclusion of a Mk 1 restaurant buffet coach in an otherwise uniform Mk 2 rake. A typical mid summer day with high pressure weather conditions has resulted in a very hazy day, with the view of Ascott-under-Wychwood village in the background obscured.
