47185 crosses the River Avon at Eckington on 9 April 1983 with the 1Z40 Weston-super-Mare to York BR excursion. I had no idea what this was at the time, but have recently been able to identify the working, the clue being the small window sticker in the first coach, showing the headcode. This can easily be read on the hi-res scan of the original 35mm Kodachrome 64 transparency.
