60010 passes Box on 31 December 2021 with the diverted 6B13 05:00 Robeston to Westerleigh oil tanks. Due to engineering works between Gloucester and Bristol, this train had travelled through the Severn Tunnel, instead of its usual route via Lydney. It would later have to reverse at Swindon, reverse again at Westerleigh Junction, and yet again at Yate, all of which explains the presence of 66080 on the rear of the train. Middlehill Tunnel can be seen in the background.
