I have several pieces of two different sized RealTrax curves there is about a half inch difference in the two sizes. My question is how do I figure out what size curves they are so I can buy enough pieces to make a circle? I'm guessing they are 31, 36, or 42 but don't know how to be sure. They are solid rail tracks.
any advice would be appreciated as I have never had MTH tracks before these.
Thanks, Nick
