Ken,
I love the various plans you have posted. I was wondering if you have generated any track plans in traditional Lionel Tubular O Gauge? I don't have or use any track planning software but thought you might have posted some ideas using traditional O Gauge track in the past.
I have a space that is 11' x 18' and would like to create a two track mainline circling the perimeter with the center open so that I can reach various parts of the layout. I will be using O72 and O54 track for the curves and a few O72 and O22 switches for sidings with accessories. Obviously, this will be something simpler than using Atlas O or Ross Switches and Gargraves track would permit.
