That looks do-able - even for me.
I do have a rudimentary questions which I’ve been reluctant to post on a public forum for fear of further revealing my ignorance.
I will be able to follow the map you’ve laid out for me but I don’t entirely understand why it works.
A good place to start - in fact the fundamental question for me - is which parts of the system are DC, which AC, and WHY
it will be a while before I get back to you on this. I’ve completed all the wiring for the entire layout and have all the trolley wiring in place under the table. However it’s an above ground trolley on the second level. I have yet to finish laying the track on the first level and will do that first.
It’s clear to me now that my first adult layout probably should not have been so large, but it will be my last adult layout as well so I don’t regret anything except how slowly I have progressed.
The pressure is on though. Of all my grandkids the one who most loves trains (8 year old) and who loves to railfan all over the state said recently, “Papa, I hope you finish your train before you die!” I didn’t tell him that model railroaders almost never finish.
I’ll be back when I have a question or with pictures when I’m done - providing we both live long enough.
