37800 Cassiopeia passes Shrivenham on 17 November 2025 with the 5Q76 10:35 Wimbledon Park Depot Sidings to Alexandra Docks, taking former South Western Railway EMU 455723 on its final journey. This was running 34 minutes late, which was good, as I wasn't in the area at the booked time. I arrived with only a few minutes to spare.
