Alex - I liked what you did with including the access ladders, though I'm not sure I'm a fan of the mutliple engine room / transformer concept. I suppose I'm more comfortable with non-exact renderings or reconstructions of the cathedral tubes.
I'm shocked by the size comparison between the two engine room sets... never noticed. I only thought the difference was the middle console!
Question - is it explicitly true that you can take 1 turbolift from, say, the bridge to all the way to the shuttlebay or engineering? Or do you need certain turboshafts to get to certain places? One circuit will get you all the way around the primary hull, and another circuit would make stops from the primary to the secondary?
