What happens when you deliberately seek out one of the few local spots that is not plagued by shadows on an early January afternoon? Yes, that's right, a few minutes before the train arrives, the sun goes in! 66621 passes Thrupp on 9 January 2019 with the 6C96 12:40 Banbury Reservoir to Bristol East stone empties. A nice clean set of wagons, but note how the rear cab of 66621 is completely covered in white dust.
