Wow Old Toymaker, I totally missed seeing your posts last year, and I frequently check the Track Plans and Layout Design section. I'm sorry I didn't see the earlier posts. Your bridges are really great! The design really has been well thought out. Building this may drive me to a bottle of Jack Daniels, and I don't drink. I agree with others, something should be done to attract less attention to the duct even if it is just painting it black. I agree with others, if you want more scenery then some sidings will need to go. I may have gone too far the other way with my layout wanting scenery and not providing for more operation.
I also hope you are coping with the family illness and death. You seem like a man if faith who can go to God in prayer.
