An intermodal meeting at Didcot North Junction on 12 August 2022, but with a considerable difference in speed. As 66548 heads south at line speed with the late running 4O90 06:04 Leeds to Southampton Maritime, the 4M71 08:21 Southampton Western Docks to Birch Coppice heads north at little more than walking speed, as 66028 accelerates the train out of the nearby loop.
