I also found it in less than two minutes and on the WGH site:

Atlas makes a track pack for this layout as well. I've always felt the NMRA's beginner's layout was a bit better than this design:

Mark, I've come upon a life lesson after a couple years in one of the United States's most competitive high schools. When someone asks you to do their homework, simply don't.
The plan is at http://www.katousa.com/track-plans/n-plans.html
I found it in 30 seconds by doing a search on "world's greatest hobby layout track plan." A lot of questions I see posted can be answered by doing a simple search. Sometimes I feel I'm doing someone else's homework.

Dose any one have a Pic of some sort of it, I never have found its desine and I've been wondering what it is.
