66230 stands on the down main line at Challow on 26 November 2017 during a Sunday engineering possession. What is not apparent from this picture, is that just a few feet in front of it is another lengthy ballast train led by 66076. They were each waiting to return to Westbury. Both trains had just moved up a few yards, after the departure of the third train in the group, but there was no sign of this moving, therefore there was plenty of time to wait for the sun to come out for this perfectly lit picture.
