HO modular layout standard?

Hi,
This is my first time here and my return to HO. I left HO in about 1987 for Live Steam. My neice & nephew keep wanting to see my HO models run.
I vaguely recall some HO modular specs that were proposed (like N-Trak) but can not seem to find any using GOOGLE.
I live in Atlanta GA. If there are any reganioal or club standards, I’ll go for that also.
Thanks.

There are as many modular specs as Heinz have pickles. The Free-Mo standards are popular (http://www.free-mo.org), and the NMRA standard is available at their site.

The nice thing about Free-Mo is its flexibility. The group I belong to uses it and we’re very satisfied with what we’ve done. See http://www.umg.pcstj.ca for details.

The NMRA module Standards and RPs are available at: http://www.nmra.org/standards Be sure to read the Introduction first as you need that info to read the rest…

You can look here for some links as well - it’s my local modular club: www.hotrak.ca . There are links to free-mo, n-trak, and others. Our standards are also on the site.
