No. Only 0-36.
Super "O" track was introduced in 1957. Switches were "tweaked" in 1958. Lionel started a long, dismal downhill slide at that time, and no further changes were made to Super "O" track.
Super "O" had some nice features. Insulated sections were available in straight and curves. Small, unobtrusive lockons fit neatly into a slot in the center rail. Outer rail lockons were clamped on. A pair of control "blades" fit into holes in the ties. ANY staright section could be an operating track. One blade was wired to a transformer; the other, to an outer rail. A small magnet fit just about anywhere an uncoupler was needed.
Super "O" curves can be bent to a wider radius. I have heard that Super "O" switches have "issues." They are non-derailing but not as rugged as 022 switches.
I prefer Lionel FasTrack to Super "O": much wider selection of straight sections, curves and switches. Switches work well.
Super "O" is good for a branch line or part of a layout. I think FasTrack has a lot more to offer.
