That is awesome! I just added the Hobby forum - https://www.challengerforum.com/forums/hooby-forum.54/ So post this up and your other projects up there!
Did you build all those buildings yourself? Post up more about your train sets in here - https://www.challengerforum.com/forums/hooby-forum.54/ Would love to see more, really, cause I love this stuff.
Nice trestle table. I see you run into the same issue as I do regarding what to use for the base. You can really blow the wad on huge one-piece bases or get "creative" with standard lumber.
