Assuming that I won the “Lottery” and could afford a larger layout, is there any way to expand an O-72 curve? (ie, using Tubular Track) As always, many thanks.
Put straight sections between each curved section. Best just get new wider radius track.
Ross sells sectional track in diameters from 080 all the way up to 0128(!). Of course that’s Gargraves-style track with the wooden ties. I don’t know whether anyone makes regular 3-tie tinplate sections higher than 072.
another route would be to use flex track and make it any diameter you wish.
If your willing to change track type as other have said gar graves has up to 138" radius
Thanks guys. I had considered all the possibilities that you have mentioned but, like everything else, I kind-of second guessed myself and thought that I may have over-looked something. (As far as hitting the “Lottery”, [:D])
