I own the AC6000 #9876 but It says in the manual says It requires Lionel or Lionel-compatible O-42 or larger track curves and this layout is O36 curve and the layout is 8' x 13' and it was built couple years ago and I would like to redo the tracks with O42 mth ReaTtrax on this track plan and not use fastrack any more and only use ReaTtrax only on my layout
