A pleasant moment last weekend in Wales was seeing confirmation of another aspect of our models which we have, somewhat accidentally, got right.
Over time the ivory colour on our carriages darkens to a distinctly creamly complexion.
Looking over at one of the sets of WHR carriage stabled at Harbour station we noticed something similar happens to the real ones.
I would assume the carriage in the middle of the picture has passed through the paint shop more recently that those on either side of it which will account for its much lighter shade.
(So I hope no insider comes on here and shatters my illusions by informing me that they've changed the paint.)
