50037 Illustrious in original Network SouthEast livery with matching Mk 1 coaches, makes a fine picture as it passes under the farm occupation bridge at Walcot (near Charlbury) with the 1B33 14:00 Paddington to Hereford Network SouthEast service on 10 April 1988. Strangely this is the only photo I have ever taken at this location!
