A nice clear shot, though a bit disappointing that 46100 is now green - which isn't a criticism of you, I know you didn't paint it. I see it's out next Saturday as well.
I trekked up to Conwy a few years ago to get a photo of 6233 Duchess of Sutherland behind the castle, only to find someone had painted it green (the loco...) in the meantime. Weather was poor on that day, too, so I got photos of a dark steam loco behind a dark castle.
