Layout shape under construction
Hard to believe, but I have a layout shape I actually intend to see through completion. Granted, most of the benchwork is already built, but this last mile was a real killer for me (figuring out relationship between staging and my railroad, geometry of the staging deck, where to put an entrance to the layout space, and half a dozen other things). Not to mention that earlier this year I switched scales and went (back) to H0 from N that I have been planning to build.
I wanted to re-use as much, if not all of the benchwork I already have, plus stick with the layout shape that is in place (around the walls and a peninsula on the center). Stumbling stone was the helix location and how it ties into the layout plus available space for it.
