66789 British Rail 1948-1997 approaches Culham on 28 March 2018 with the 6E45 12:05 Theale to Immingham empty oil tanks. It was raining when I arrived at this location, but this train was running half an hour late, and by that time some unexpected sunshine was occasionally breaking through the clouds, hence the less than ideal backlighting. Even with the late running, there was still plenty of time for another picture the other side of Oxford.
