Go get those glue sticks! A pack of 50 is less than $5.00 at Wal-Mart. Also make sure you have a utility knife, leather gloves, safety glasses, a yardstick, a sharpie, and kraft paper (or more boxes) to cover the floor. About $10.00 worth of craft paint will help a lot.
I’m a module guy, so I have a lot of mental experience with the 2x4. The very first thing I’d point out is drop at least one track and probably two. Once you broaden those lines out to roadbed width, you’re looking at almost 50 percent of your surface being roadbed. The vertical shifts you’re going to have going from front to back are going to be so abrupt and sheer that you’re going to have more a wedding cake look than I think you’lll want.
So ditch two tracks and leave only two instead? I’m going to be getting some flex track to help the mock up process, I got the base built but then realized I need some track to fiddle with to figure out the arrangements…
I got the base assembled by gluing two layers of cardboard together to make a 2’x4’ drew a 3" graph on it an tried transferring the track plan to it… I’m going to have to get some flex track to get the arrangements right…
Great! Check out this video, all shot on a diorama. He (Jurg) has different dioramas he uses in his photography.

EDIT: Clicking on the bottom video doesn’t always get more Jurg videos. Search for him on Youtube. He did 6 HO scale collection videos, and another called Let it snow. They are all just as good as the one you watched. Music, modeling and all.
