I would love to see superO made again but Lionel told me a few years ago that most of the tooling for superO has either been lost or destroyed. If that is true then forget Lionel ever doing it.
If just certain pcs could be made like 30"straights, wider radius curves and better switches I think that could be a start.
New tooling is expensive so either a company or a person with very deep pockets need to be involved and in the end how much would it cost to the hobbiest for the track. If too expensive it could kill the whole project.
With all the negatives I still think it would be a great track system to do again. Let's hope!!!!!!!!!
