O/On30 Garden Layout?

How great!
The viaduct may be a little too large, and a little out of place for me, though. Maybe next time. I really want to do an On30 layout based around logging and mining. It would involve tunnels, inclines, many plants, and even a water feature, I would think. I drew up a quick "to portray my point" plan. The line extends along a side yard to a loop that brings it back at ground level again. It will most likely be a logging branch and possibly another yard on the lowest side, but will pretty much be two tracks, one going out, the other coming back, so I excluded it from the plan.

I will just say this. In Large Scale (#1 gauge), you can get your arm all the way into a tunnel for derailments, debris removal, etcetera. On narrow 0 gauge, might be an issue on maintenance. One of those tunnels has no track above it, so a lift out panel is do-able, but the other two, especially the yard, might be an issue.
Concrete is always good base....rebar......either drill and install nylon inserts or imbed TREX sections for screws. I know what regular wood will do when concrete is around it. I have some really well defined 2" square holes in my concrete where I didn't use TREX.

Dave,
I left the tunnel under the yard straight and relatively short, making it easy to push any derailed cars or debris out with a pole of some sort. However, tunnel on the right side was concerning to me. If this all does go through, I would most likely create a way to access it from the side, perhaps a removable rock or something similar. Thinking about it now, I may create a connection between the outer loop around the tree to the line just before the tunnel, so I can have a temporary loop to run while the largest part of it is under construction...

Can't even get it all in one picture. Big trestles are always eye-catchers. I have one tunnel under the upper yard...track is screwed to a board, nestled in pea gravel, so I can disconnect and drag it out. Had to do it once when a neighborhood cat decided to take a dump IN the tunnel. A scheduled wayfreight found it.I have always thought the 4 tracks in the yard could be done with 4 short bridges over a cut, if it came to that.
