Mine is also small potatoes, but I'm so glad that I built it with elevated tracks. It's much more fun to see the trains pass by at eye level, which definitely outweighs any benefits of lineside structures and scenery (though I may eventually add a few buildings). It will have to be replaced/relocated if we move ahead with our eventual plan to add an extension to the house. I've been informed by an expert on construction that it will take 5 min (if that) for the contractor to remove the posts set in concrete.
