Hi Tom,
Yes that's the basic idea. I have a walkaround layout, 6 feet wide by 24 feet long, and I want to be able to individually control the trains.
There is a center full length backdrop that separates both sides, so I'll put in extra UTC\P plugs and be able to have control on both sides of the layout.
I have one Pro Cab throttle now I purchased with the power pack setup etc.
I probably won't run more than 3 to 4 trains at once. I have two main lines running now, and still
adding to my layout.
