Bob,
I didnt find working Franklin Falls that dificult, but i am used to the short run around tracks on my layout. I found it adds to the chalenge. so making the tracks a little longer and finding a way to fit in a wye or a turntable is all that is needed. my wye turnouts are 5" R and work fine. Could you extend the wye out beyond the fence and have a remote choke cable operation on the Switch?
