Responding to this part of Will’s post above: “What are my options for easements of various lengths using wider radius? There would be several ways to do this depending on what radii were available and how gradual I wanted to make the easement or maybe how much real estate I had available without crowding my aisles.”
As long as the constant radius you wind up with is not too tight for any of the equipment you will be likely to operate, you can sacrifice a bit on that by tightening the radius to compensate for the “real estate” loss caused by the easement offset. That will allow you to keep your aisle width constant, and the appearance of your trains operating on the resulting curves will be better than with the slightly larger constant radius, but no easements.
