well when you think about it, Diesel does represent the CGI version, I mean, just look at his face, and yet he has silver side-rods, I'm guessing that they stayed silver because Bachmann wouldn't paint side-rods that stick out so much, and would get bumped and scratched up..?
in other words i just have a feeling that even though Arry and Bert will have CGI faces, they'll still get silver side-rods, like Diesel.
EDIT: Something that I've noticed with Arry and Bert's wheels, they dont have the counter-weights like a normal class 08 such as Diesel (by counter-weights I mean that half circle on the oposite side of the wheels then the side-rods)
This is the best example I could find; http://images.wikia.com/ttte/images/8/8b/DayoftheDieselsTrailer6.jpg
