An impressive cloudscape, but a less than impressive train! 800015 is a poor substitute for the HSTs that formerly traversed this line, prior to the downgrading of the service to unit only operation in 2019. The train is the 1B11 10:48 Paddington to Swansea GWR service, pictured approaching the site of Ashbury Crossing, Shrivenham, on 10 February 2021.
