What Radius of Lionel Fast Track should I use for the MTH Canadian Pacific Christmas Train. I'm confused as to what radius works good ?

here you can get look at it running on O36 on a 4 x8. Follow DKDKRD's guidance.
Very nice display Carl! Marry Christmas!
Is O-72 = 72 inch diameter circle ? and so on

Looks great Carl! Is that the premier or Railking version?
Guys, it is not my layout. It's a friend of Big CrabCake. He posted it on the other forum. Watch it on YouTube to see the owner's info.
I thought it would really help the OP decide which diameter curves to choose. The timing was good.

Yes, the size of 3 rail track curves are described by diameter. In the case of FasTrack, the dimension is measured from the center rail.
I run mine on super O o36 track and it runs great.

Yes. O gauge track is not referred to by its radius. The number refers to its diameter. So O-31 is 31-inch diameter, etc.
The smaller scales use radius references for sectional track. For instance, the common HO curved track used in train sets is 18-inch radius, meaning a 36-inch diameter circle.
