Hi Richard,
Looks like you're off to a good start with a fun & attractive layout planned! One thing I've found out the hard way in recent years, is the importance of easy access & maximum reach.
One purchase that you can't go wrong with is "The DCS Companion 3rd Edition", by Barry Broskowitz, & probably can answer almost any question. I believe it's still available from MTH and for sure on Amazon. Personally, I prefer watching how to video's & take notes as I go along. Rich Battista's videos of his Black Diamond RR offer a lot how to information on building a complete layout & the video quality is top notch. The Forum is always a good place to start for suggestions & direction to go, although not everyone always has the same opinion. If you read the following thread on the forum, you'll see what I mean, "Does the DCS signal still need star wiring or can we do buss wiring?"

That particular thread may not be your answer to how to wire your layout but how many different opinions are out there.
The MTH terminal block below is a good place to start to help keep your wiring organized. I have 2 on my layout.
I can't stress enough to work neatly & carefully, testing as you go along. I started having issues when I added my switches. I used Atlas O exclusively & there early switches have always given me problems & eventually replaced most of those with Ross.
Since wiring is probably my weakest link in the hobby, as I come up with other suggestions where to find help, I'll pass the information along.
