@RSJB18 posted:An 036 loop of FT is approximately 39" to the outside edge. 031 is approx 34".
I'm planning on a 36" x 80" O Gauge layout because of space issues. Since I have both Rail King and Post War I'd like to run, I'm wondering whether to go with tubular or Fastrack? Is there any scenario in a 36" x 80" where one gets two loops, 031 and 027? (I'm doubtful because of clearance issues, but I wonder if tubular gives one an edge?)
