I thought it was...
... a steamily warm afternoon in York; but there were differences in opinion on this, as you can see. I took these two shots minutes apart. Blip sorted!
I headed back to York Station to catch my return train and was surprised to find men with cameras everywhere (I didn't see one female photographer, honestly). The reason soon became clear.
See today's extra - I managed to take just one shot of the Flying Scotsman, which departed just before my train (with no name!) opened its doors to passengers.
