This is stunning work. I have plans to put an elevated section on my HO layout and I'm thinking of either using the Micro Engineering product, or the imagine That Laser Products.
Thank you for the kind words. I follow your blog and I am very impressed with the speed and skill you show. For HO structure, you could also try Curt Seegler's (spelling) line of HO structure called Elwood's Elevated. He showed it at the 2011 Mass Transit Modelers meet.
