I do like that one! If I might make a constructive suggestion, it'd ideally work better with a shorter train - partly for authenticity, partly to see the loco, partly for composition... Admittedly short trains aren't particularly easy to come by on the valley (save the drivex, which is perhaps a little too short!), but maybe an early morning run on a gala day with 2-4 coaches, before it gets too busy? Just an idea!
