Hi paigetrain,
Without knowing you goals in thinking about S gauge, it is hard to give much advice. If it were me, I would say stay as far from Flyonel as possible, especially their repro accessories. I just took a look at eBay and there is so much original Flyer at very reasonable prices that you don’t have to think about Lionel’s future plans for S. I also recently read that Scale Trains plans to reintroduce the SHS line, it doesn’t get any better than SHS. There is also American Models to look at along with S Scale America and several more.
Again, just my option, but I would stay away from original Flyer track (sorry Ray) and go with Fox Valley flex and turnouts. MTH/SHS flex is interchangeable with the FV trackage. There are also a couple of brands of S gauge track in pre-formed roadbed, though the MTH/SHS line is getting harder to find.
The NASG web site will give you tons of info about S scale, there is also a pictorial of Bruce’s layout along with the TM video. Looks like Bruce used a combination of original Flyer track and switches with Gargraves flex for wider radius curves.
Good luck and have fun,
