A layout I’m contemplating would use a combination of American Models track products- -which I would purchase- -with Lionel AF FasTrack components, which I already have. The former would be utilized for a stub passenger terminal, coachyard, and adjoining visible trackage, while the latter would comprise the rest of the layout, much of it consisting of loops hidden from view.
After “ramping up” one or more sections of AM sectional straights to gradually match its FasTrack counterpart’s height, what would be the easiest way to physically and electrically join these two different brands of track?
