800005 passes a superb display of blackthorn blossom at Circourt Bridge, Denchworth, as it heads west along the Great Western Mainline with the 1B15 12:48 Paddington to Swansea GWR service on 19 April 2025. It was on time here, but after Bristol Parkway it would revert to GWR's usual timekeeping, and would arrive at Swansea 37 minutes behind time.
