Hi all, I have for the top level of my layout I have a 7' by 10' flat surface. I plan on having an outside loop using 48 inch curves. I want to stick entirely with Fasttrack as that is what the lower level has. If I create that outside loop using 48 inch curves. Will I have room on the inside for another track? I would like something other than just a "loop" on the inside. I like the class toy train look and maybe a figure 8 or dog bone if it can fit. Can anyone describe what I can fit for the inside track?

thanks

Frank

...each diameter of fastrack is made to fit inside each other. For example 36" fits inside 48", 48" fits in 60", and so on...

Until you go to 31".

It doesn't fit.

IF Lionel had used the original 14.14" center rail radius for 31", like MTH did for their O-31, then it would have fit. Of course, in FasTrack terminology & geometry, it would have to be called FasTrack O-28.28!
