(BTW, nothing new about asking for a semi-scale J - a number of us in previous threads going back awhile have been asking for a LionMaster or at least a Lionchief Plus N&W J. Obviously, Lionel has yet to deliver.)
This thread is in the S Scale Trains Forum.
Every locomotive Lionel has made for American Flyer will negotiate R20 (20" radius) and is very likely to do so in the future.
