166211 passes Purton in superb late afternoon light on 17 September 2018 with the 2G89 17:54 Swindon to Cheltenham Spa GWR service. Collins Lane level crossing can just be seen in the background. I might not have waited for this if it had been one of GWR's much more common drab green liveried units, but as I had seen it heading for Swindon just as I arrived, it was definitely worth waiting for another picture of a unit in this much more attractive colour scheme.
