Can anyone tell me the width in inches that Fastrack will make to form a circle. I know the roadbed will add to the width but have never worked with O31 curves. Any information will help. Newbie to the forum.

Fastrack O31 makes a circle with a center-rail diameter of 31" (different from the traditional O-gauge track).
The (good) rule of thumb for Fastrack is to add 4" to the designated size for clearance of the roadbed. For instance, Lionel says that its O36 track in a Ready-To-Run set makes an 40"x 60" oval layout
