Thank you everyone for you ideas and advice. I am going to stick with conventional operation right now. Nothing against digital, but I need to draw a line in my own budget and use what I have already been collecting and accumulating for years.
Keep sharing photos of your layouts.If I never get the thing built, at least I can dream about what others have accomplished!
You may enjoy this chapter in my layout story. It may provide something of a perspective on tackling such a project.
The first chapter was my Uh-oh Moment, which was when I took delivery of my order from a local lumberyard of twenty 4'x8' sheets of 3/4" finished-on-one-side plywood. Along with them came all the legs and frames, cut-to-order, of the 2x4's that would constitute the frames and legs for the plywood "platforms," as I had become accustomed to calling them from my childhood in Pittsburgh.
The entire load arrived and got temporarily stored in our 2-car garage, adjacent to the basement soon-to-be-trainroom, which was only the first time our cars had been exiled to the driveway for storage and work space and safety.
As I looked over all that wood, I was intimidated and wondered if I had made a BIG mistake. However, all that lumber smelled great, stimulating my creativity and need for adventure.
I constructed the first "platform" with the help of my wife in up-righting it from its upside-down position on the basement floor. The whole procedure took 30 minutes and felt real good.
Every day, when I returned home from teaching high school, which has always been my favorite creative adventure, I'd immerse myself in the basement, building the twenty platforms, bolting them one-to-the-other, and eagerly faced the next creative chapter - configuring the track.
I loved it all.
When you feel like playing trains, you will, and in your own unique way, taking what feels best to you from all our advice and viewpoints. Have fun. I almost envy you the creative adventure ahead of you. There are few things in life quite like building your own model train layout. IMO.
