A wave from the driver of 37421, as the 1Z78 06:48 Bristol Temple Meads to Tyseley Network Rail test train passes through Ascott-under-Wychwood station at high speed on 3 November 2016. Barely visible on the rear is 37025 Inverness TMD, which I had photographed in some much less favourable lighting at Bourton a short while earlier. The bright sunshine was a little unexpected, and did really narrow the choice of Cotswold Line locations, but did allow the very necessary 1/2000sec shutter speed even at ISO 200.
