Running 17 minutes early, 56312 Jeremiah Dixon Son Of County Durham Surveyor Of The Mason-Dixon Line USA approaches Quainton Road on 6 February 2015 with the 6Z35 10:16 Calvert to Willesden Euro Terminal spoil empties. With a clear and frosty morning forecast, I didn't expect any problems getting this picture. However, as I passed Bicester, I drove into a huge bank of thick cloud. I almost considered turning back, but persisted, and decided I would just get a dull record shot. Surprisingly, the cloud drifted off to the west in time for a perfect sunny shot!
