Having photographed Class 50s on the Cotswold Line in the 1980s, I certainly wasn't going to miss the Pathfinder Tours 1Z50 05:20 Didcot Parkway to Appleby 'Cotswold - Eden' railtour on Bank Holiday Monday 26 August 2019. Dunstall Bridge, near Moreton-in-Marsh seemed the obvious choice, as there would be nothing to obstruct the very low sun. Fog was predicted, but on arrival only a couple of small patches of fog in the background merely added to the early morning atmosphere. However, just before the train arrived, the fog unfortunately increased considerably. 50049 Defiance & 50007 Hercules are seen here emerging from the mist, several minutes after they could first be heard powering up the Evenlode Valley.
