43010 passes Charlton-on-Otmoor on 17 September 2017 with the diverted 1B51 14:58 Paddington to Swansea GWR service. The concrete track provides access to Holts Farm, replacing the former level crossing, which was situated near the rear of the train. As this just about the best photographic location between Bicester and Oxford, and given the rarity of HSTs over this route, I was surprised to be the only photographer present!
