After working the 5Q78 06:11 Birkenhead North EMU Depot to Newport Docks (Sims Group) scrap EMU move on 15 January 2024, 37800 Cassiopeia returned light engine to Derby, in order to work the following day's 5Q65 12:45 Derby Adtranz to Oxley, conveying new 730 units. I wasn't in a position to photograph either of these trains, but here is a picture of it passing Defford.
