To remain consistent with FasTrack geometry, and in a departure from tubular "O" geometry, FasTrack O31 really is 15.5" radius, with an overall diameter including ties & roadbed of 35".

"O" is 14.14" radius, so there may be some wiggle-room on what will run on the FasTrack version.

Rob, since I know how much you like accuracy, I thought I'd share this with you and anyone else who may be interested. On FasTrack the outside diameter including roadbed is 3 1/2" inches wider than the center rail diameter. Here are the real world measurements I have taken of actual FasTrack and other bits of related info about FT curves:
