NASG S-MOD Standards

The NASG S-MOD Standards were developed so that S scale modelers could gather from anywhere and easily join their modules into functioning hassle-free layouts. These standards have been accepted by the NMRA Engineering Committee as the basis for the NMRA’s “S” standard gauge module standards. They accommodate scale standard gauge, narrow gauge, and/or hirail.

Please view a complete listing of S-MOD standards.
