Neatly framed by the overhead gantry, which otherwise is nothing but a photographic nuisance, Plasser & Theurer Unimat 09-4x4/4S Dynamic Tamper DR75011 Andrew Smith passes Uffington on 20 April 2021. It is nearing journey's end, as it is running as the 10:27 Swindon Transfer to Challow. It would then sit on the up relief line for most of the day, before returning to Swindon in the evening, via a reversal at Foxhall Junction.
