43005 brings up the rear of the diverted 1L53 10:24 Swansea to Paddington GWR service, as it climbs the steep curve between Gavray Junction and Bicester South Junction on 17 September 2017. As can be seen from the clouds in the background, sunshine was at a premium (at least until later in the day), and I was lucky that this corresponded with a short sunny period.
