@Dennis Rempel posted:Such as Gargraves, Atlas or others. and any radius you want.
I notice on the what is your radius thread everyone had standard sectional track radius.
I did a small layout with a friend using 5 rail (O and Standard gauge combo) Gargraves flex track.
Difficult to work especially on the ends of the curves. But the final result worked out great.
I would imagine that 2 or 3 rail O gauge Gargraves, or HO and S would be a lot easier
