50008 Thunderer passes Yarnton on 17 February 2022 with the 6Z50 11:26 Eastleigh to Kings Norton On Track Plant Depot barrier vehicles. It was lucky that I had arrived here a little early, as it was running nine minutes early, having not stopped at Oxford as booked. It was also lucky that the sun was behind some thin cloud, as this location would otherwise be exceedingly backlit. Instead, there is just enough brightness to give some contrast to the picture.
