Lionel's AF Catalog (and RTR Catalog) is on-line

I am interested in the new AF FasTrack system as I may be getting my grandfather’s AF set…

Now I noticed Lionel ONLY has 20" diameter curves, but ALL of their engines and rolling stock require 36" diameter curves! I think someone at Lionel’s editorial staff didn’t do their due diligence and review this catalog very well.

Nothing in the RTR Catalog caught my eye…

The curves are 20" radius 40"diameter. They are similar to S-Helper track and have the same track geometry as traditional American Flyer track. Therefore all of the new products will operate on them.

Thanks for the clarification Major - makes one wonder why they would have different annotations though. In the O gauge catalogs everything is listed in ‘diameter’.
