This is another take on ballasting - finer ballast in the center, rockier stuff outside a little. Per typical narrow-gauge, the center area does have ballast on top of the ties (actually done to encourage water to run to the outside, when ballasting with dirt or other materials). Notice the two tie colors... after review by other authorities in the house, the tan color will be used for most of the trackwork going forward.
|So here's a close-up of some actual trackwork.|
|The river exits under RGS Bridge 42-A.|
Above, this shows the river exiting under RGS Bridge 42-A. There really was a river on Keystone hill, running out under 42-A, but obviously the topography was different. I'm after interesting visuals here, not an exact duplication of the prototype hillside, which would be less interesting in this greatly compressed space. The river, from this view, will twist right and out of view behind rock walls (not yet roughed in behind the bridge).
|So here's a view looking down the track, thru part of the canyon.|
Above is the same section of track, but from the other side. Here, the river's on the left beyond the cut, and bridge 42-A is at the very top of the track that's visible here. I'm sticking some of the cardboard very roughly here - just trying to visualize the overall sight lines and view blocks. I'm using drywall shims, btw - what you see here is less than two 50-piece packages - about $8 or so at Menards. And a LOT easier than cutting all this cardboard! It's really strong too.
|One last shot - river on the right again|
One last shot - river on the right again. You can see how the river is descending in a canyon that's getting deeper, with rock walls getting very steep. The hillside along the track is also gradually getting steeper, building to the cut beyond the bridge (just visible as the track curves out of sight to the right in this shot). And again, although this is only about 10' of track, the curves and view blocks will - hopefully - make it seem much longer.
