66621 moves onto the up relief line at Wolvercote on 11 January 2019 with the 6C96 12:40 Banbury Reservoir to Bristol East stone empties. This train is a bit random, and whilst it always runs to time, it only seems to run on about half of the booked days. Note the new livery for the MWA wagons, which includes a yellow stripe along the base, and over the lip of each wagon. Also, the new yellow and orange Freightliner logo, part of the company's rebranding after being acquired by Genesee & Wyoming Inc.
