John, bear in mind that these are just samples to show you what an around-the-room layout might look like. Here are some photos with a 28" turntable instead of the Wye. Note that I added 2 bridges, raised them to a flat 3" and adjusted the grades on both sides. All grades are 3% or less. I even added a storage yard for rolling stock,though it's quite far from the turntable.
You can have 2 or more trains running on each track in opposite directions so they pass each other and go over/under each other. You get all the visuals you'd get from reversing loops without the added expense and limitations, the biggest being a single mainline between them.
