60019 Port of Grimsby & Immingham passes Stroud on 9 October 2021 with the diverted 6B33 11:42 Theale to Margam Murco oil empties. This was diverted due to the closure of the Severn Tunnel for engineering works. It was running late, having left Theale 73 minutes behind time. Because of the easy schedule, it had picked up some time, and was only half an hour late here. This was excellent, as at the booked time the whole area was under heavy cloud, but just a few minutes before it was actually due, the sun reappeared!
