I have the Lionel Polar Express S-gauge set on order and wanted to get some larger diameter track. I know MTH makes S-gauge track, and Lionel does as well under the AF name. Both have plastic roadbed but I am wondering if they can be joined together? Also, for the MTH 30 degree curves, how many make a full circle?
I could not find any information on MTH's website on their S-gauge track.
