PaulC, so glad you posted.I'm sorry you are confused and I guess I am even more confused. I totally agree with your comments and in particular the fact that there is a lot going on - I didn't realise that until I actually looked at the drawing, looked at some 00 gauge track and looked at my available space. Yes, it certainly has too much happening.
Furthermore, when I think back to my youth and recall the railway that passed the back of my house, it was a single line on a raised embankment and nothing but grass and landscape either side. My approach, as you rightly pointed out, there is little scope for scenics.
Well PaulC, thank you kindly for stopping me in my tracks - I honestly do appreciate it.
