Does anyone know what the diameter of this track is? I put a loop together and measured 35” center rail to center rail. Close to 37” outside rail. Don’t know if I’m just not putting it together tight enough. Maybe it was meant to use with a half track (a little over 5 1/2”) to make the spacing 10” for a 31” inner loop. Going to use it as the outside loop on the Christmas layout this year.
