Looking for some comments/suggestions on this layout.
On the-floor in basement over hardwood laminate flooring. Fastrack. Approx. 17' x 15.5', but might have couple inches of flexibility. Have had the inner yin/yang loop on the right side already, along with partial siding, and the outer loop (running). Missing a couple switches for yards, wye in center, reversing loop on left, yard/switches on angle, and outer loop 84" radius curves - currently using 72" with some short straights. Right now, outer loop is Lionel Legacy 990/Cab2L (with TMCC/Trainmaster/Cab1 as backup). Inner loop is MTH DCS TIU. Power via 2 180W Lionel bricks. I want to change it up a little.
Want to run fairly long trains. Articulated steam, probably mainly on outer loop. Diesels on inner loop. No accessories right now. Just trains. I've enjoyed running multiple trains (2) on the inner loop simultaneously. I'd also like to do some siding/switching.
Can't really deviate from the chamfered rectangle approach due to stairs coming down and outer basement walls. Filled 1'x1' blue square is a post I need to work around. 4'x6' transparent rectangle is my workbench. I have some flexibility here, but not much.
I've thought about joining the outer with the inner, but not quite sure what that does to my power scheme. I assume I need to insulate/isolate inner/outer, but what happens when trains cross the DMZ between outer "Lionel" and inner "MTH"? I know I can control the Lionel with my MTH DCS remote, but can't do the reverse with Lionel remote. If I'm running an o72 articulated around the outside, there is only so far I can go on the inside, as it drops to o60 i the very center of the left reversing loop. But I think if I make a double crossover (5.4" c-c version) with 4 o72 switches on the far right, I can get outer loop trains to reverse, too.
I'm open to suggestions. Planning on looking for track (even used, but good condition) and switches at York.
Thanks, Dave
