43172 Harry Patch - The last survivor of the trenches brings up the rear of the 1L54 11:56 Cardiff Central to Paddington GWR service at Uffington on 19 October 2018. With only a few months to go before the HSTs are completely ousted by the Class 800s, it was noticeable that there were only a minority of trains still worked by the old traction on this day.
