First, good move switching to XtrkCAD. Although some people like Phillip get good at the program, most people I see that use it end up getting limited by their abilities with the software. Stuff like not being able to get the tracks close in yards and dual mains etc. XtrkCAD is a lot more versatile and there are a lot of things you can do really quickly like build yard ladders. If you locate the turnout in a yard throat. I can build a 10-track yard in under 15 seconds.
Comments on the layout design.
The good.
Lots of staging.
Set-up for railfanning.
Inexpensive design
The not so good.
No variety. at 1 hour per day, you'll have run 350,000 laps before it's done.
There's really nothing else to do. No industry. No chance for interchange.
With your intelligence, you'll be bored before you start your scenery. So what you need is experience to find out what you like to do. You live in a decent sized town, see if there's a model railroad club. Your LHS should know if they are there. Get in and run some of the trains. See what you like.
Now don't feint. Post a list of the track you have left from years ago. Let's see if we can put together a fun little temporary switching layout or puzzle. If you like that type of thing, you can incorporate it into the layout.
