Upper Level Mock-Up; Your thoughts are appreciated.

Sounds like you wont be doing a ramp between the two levels.  Therefore experiment with higher second level to improve visibility under.

Ogaugenut, that is correct. I had contemplated doing that early on but it created other compromises. So when I saw the article, the light bulb went off and I realized I didn’t have to make it complicated.

I’ve seen this type of track plan in a number of iterations. You have to decide what you want that lower level to be. If it’s nothing more than a pass-through, what you have here is fine. Or, you may want to consider modeling the interior of a train or subway station. That would lend itself to the shorter height and make it as if you were peering inside the building. Otherwise, I agree with the above suggestion that you may want to increase the height depending on what you're  modeling or the scenery we will be.

VJandP, thank you for your response. For the purposes of viewing the foam is 9” high; it could be higher. In the second photo I did a mock up of the island platforms which will be lit and have stairs, an elevator, etc. My  visual is of the PRR platforms at the 30th Street station in Philadelphia. There will be a wall installed on the far side of the third track. My other visual, and catalyst, is the article I noted in OGR run 327.
