  1. Why would you spend a lot of time modeling the real prototype, then create a trackplan that has no resemblance to the real place. Ridgway Colorado yard is depicted on the layout, but has no similarity to the actual prototype itself. The whole layout is messed-up in that way. In that case it should have freelanced.

  2. Would like to have seen a photo of his shelf structure — 1.5″ L plus 1/2″ plywood on a shelf beracket. How are the brackets hidden? Otherwise a good article on a very nice layout.
