Building New Layout

My layout is in a 28' x 14' (living/dining) room and is a dual-mainline, around the wall with a center peninsula.  The main viewing/operating aisle is 3' wide, and the rest are 2' wide.

The yard occupies the entire 4' wide peninsula.  Six feet would be the maximum width one could realistic do if more space was available, and should give one room for a turntable, etc.

Thank you Jan, That looks like a great starting point for me.  I appreciate the time you took to help.  How many power blocks do you have on this layout?

I use 3 channels on my ZW; one for each mainline, and one for the yard.  The fourth channel runs everything else.

I'm working on a redesign that adds staging under the track on the top which results in a third independent loop.

I will be able to run three independent trains (excluding the yard) with one on each loop, or one train going three times around which doesn't cross over itself.  It would  be a train 225 feet long .

A 180w brick can support two trains unless you have something (like incandescent lights in passenger cars) drawing more than its share.
