D500, thank you for the info. I suspected as much, but was not sure. It is never "too late" to start over in modeling is it? I currently have my 2-rail O scale, and just a few years ago, dug out the old conventional Lionel, and am building a small layout with my grandson. Heck, I am almost 72! I have 2 rail in the spare bedroom and 3 rail in the garage. Plus, a very understanding wife.
