D8001 & Class 08 13018 approach Chinnor on 19 May 1996 with a train from Thame Junction, during the Chinnor & Princes Risborough Railway's Diesel Gala. This line runs along the base of the Chiltern Hills, the wooded slopes of which can be seen on the right. Although the lowest numbered Class 20 under TOPS, this was in fact the second locomotive to enter traffic. The first, D8000, became 20050 upon renumbering.
