This sounds like an excellent approach to operations! One question: are ou planning to use sectional track or flex? And if sectional track, which brand?
The final plan you posted looks very promising - I have a few suggestions:
1. Do you really need the loop of track on the north end? One of the tracks through the yard will be the main line.
2. You probably don't need the crossovers that I have circled

Hi Kleiner, thanks for the questions and input!
As far as track, I was thinking Pico code 83 flex, and Pico #6 turnouts. I haven't gone as far as pricing things out or checking availability yet.
So the outer north loop was from the original two track concept. Even in the one track layout, the north loop still serves as access to the industries on the east side. I further modified the east industry before reading your input. I do see your logic in removing it. I might experiment with moving that turnout further south, and repositioning the first turnout splitting into the yard so the yard access turnout could go further north, but turnout spacing might start to get tight further south. One thing I'm trying to do is not go any tighter than 24" radius in the curves. I'll probably share the latest version as I had it before I read this for you & everyone to have another look.
The crossover on the upper most track of the yard where is initially put in after watching an interesting video on YouTube that describe some benefits. However, given I'm still learning of the functionality on so many of these details, I wasn't sure if it was better in his case due to the fact that his yard was stub ended, and whether or not my proposed yard being double sided would negate the need for such a crossover. That video can be seen here.
Before I read your reply here, I had already made a few other iterations on what I've posted so far in both the sigle and double track option. I'll share them here over the next day or two, as I'd love to get further thoughts from you and everybody else willing to take the time to check it out.
