From Miniature to BIG

I knew you'd love the rivets lol  Something you always seem to get with LMS locomotives, I think the LNER ones used to be designed with flat rivets, but that probably had something to do with the air streamlining of locomotives such as the A4 (Mallard for example) class.  It is always interesting some of the restrictions these innovative designs had, I wonder if the model is similarly deliberately handicapped if running in reverse?  I mean it wouldn't surprise me in some ways as they are constantly trying to make the models more and more realistic
