I have a 2010 model year Lionel Big Boy #4006 LionMaster, so same semi-scale size as the LC +2.0 Big Boy. Here's a photo of the loco in an O36 curve. On my layout it will tap a couple of trees with a 2 inch overhang at the cab. The front has very little overhang. On my layout only the middle loop is 036, the rest of the layout is 048 and my Big Boy looks less ridiculous on 048.
