With the end of the Rail Head Treatment Train season in early December 2025, the RHTT sets were moved back into storage for another year. Class 57s had been used on the Wiltshire and Somerset diagrams. 57303, 57305 & 57306 are pictured passing Uffington on 8 December 2025 with the 3Z56 08:50 Taunton Fairwater Yard to Tonbridge West Yard, which was running a few minutes late, as it has been held at Swindon because of a late running GWR IET.
