Is there going to be a backdrop is it is a island setup? Having a front and back will change how things get laid out.
Certainly the S-curves might be a problem if you want to run high speed trains through as part of a future layout. If not, I think you're probably fine. For the S-curves on the trackplan I posted, the curved track is 41" radius while the upper turnout is a Peco medium and the lower turnout is a Peco small. I don't know how well that plan matches what you have down on the door already, but it looks pretty close. I saved some space by making one end of the crossover part of the S-curve (also greating one route through the curve that's gentler); I don't know if that would match up with what you have down on the board right now. I realize many people here suggest doing design with pencil and paper, but if you're at all inclined, I'd suggest using some sort of CAD program. For tight spaces like this, the actual size of turnouts ends up being one of the most important considerations, and you can't accurately gauge that using pencil and paper. CAD programs also allow you to easily measure curve radii. I like XTrkCad (mostly because it's free), but others are fine too (though the Atlas software really isn't, I'd avoid it).
I like these kinds of plans, and yours is an interesting one. Is there enough room on the runaround track lead at Warehouse #2 for both a freight car and a locomotive?
As I've posted elsewhere on this forum have a look at http://www.carendt.us/ There are some very interesting ideas there
Does this help? a combined HO Inglenook/Timesaver for 40' cars and a GE44-tonner Adjust the lengths for 50'cars and an SW1200 which will then be about 78" long
Have you looked at Carl Arendt's collection of micro layouts? There're a lot of switching layouts. Wolfgang
