Track center line seperations should be adjusted by something SIMPLE (in inch-fractions or centemeters) rather than something that would be hard to remember and subject to argumentation ,,, such as trying to adjust to the scale equivalent of a popular prototype.

Tighter radius curves for intra-module and intermodule branches, passing sidings and yard track should again be SIMPLE and easy to communicate/remember ,,, as with turnout numbers. With regard to the latter, commercial product availability might well dictate, such as setting #4 turnouts as the norm.

I am not familiar with Sn2 standards and thus have no comment, but I opine, with respect, that the prototype is fairly scare and that might lead, again, to arguments between clubs. Despite its growing obsolesence, Ntrak had for roughly three decades the advantage of uniform standards and massive consensus.

Supposedly a group in Colorado has taken the Sn2 standards and applied then to HOn3.

It is a pleasure to have you visit and comment on my site.

I looked through my website drafts and other info and didn’t come across any info on HOn3 Free-mo. I did have some stuff on On30 and Sn2 and Sn2.5.

Probably the closest to something useful to HOn3 Free-mo is this white paper on various On30 Free-mo interface plates – http://www.vif.com/users/r-rhurlbut/On30-Modules/Free-MOn30/Interface.pdf

They are very similar to Harold Brosch’s Fremo endplate profiles – http://www.eisenbahn-modulbau.de/catalog/default.php?cPath=98_22

That’s about all I have found.

Thanks,

we are a part of the European FREMO who are interested in US-style railroading. Now we’re looking for information about H0n3 modular information.
Are there at FREE-mo any H0n3 fans? Have the established some standards?

Any information will be good. Thank you.
