thanks swankyMonkey, it's getting kinder difficult at the moment as I only have back and side view references.I am working on all the linkages and various parts under the train and the only breakdown I could find of how it all works and fits together is from a web site of a guy that built a quarter scale replica for real ..lol
So I have about 60 pics of the parts he made and I am trying to relate those parts to various photos and my image planes to fit it all together, it's little tedious but I am getting there slowly.
