John, if you are considering raising the town above the tracks. Experiment with cardboard or foam raised up on whatever you can find to get the height you need. If you have some buildings that would help or even cardboard boxes to represent buildings. If you come up with something you like. Give it a few days just be sure before you get into the build.
I was more focused on the town or road. Bob brings up a good point about the lead to the turntable of just having a couple of paths to get on or get off it. The curved turnout I mentioned leading to an industry such as fuel dealer. If you are modeling the steam era. A long team track might work with a loading dock. Low enough that it can easily be reached over. You can service it with a variety of cars and detail it with all kinds of commodities being loaded into trucks. Or even to offload automobiles.
