O Scale Central is also a National Model Railroad Association Special Interest Group (SIG) representing 1/48 scale 2 rail modeling within the model railroading hobby.

NMRA is the organization for all model railroading scales and interests.  The NMRA.org website has a lot of information for all scales.  NMRA Interchange is being expanded on Discord with many Channels for discussion and information exchange.  The NMRA manages Standards, Recommended Practices and other technical information for the hobby including the 1/48 scales.

Many model railroading activities are organized by NMRA local Divisions and Regions.  These events include layout tours, modeler meets, conventions and the NMRA National Convention each year.  These are excellent places to meet other modelers in all scales with common interests.  There are probably NMRA members within a few miles of your home.  Many times, modelers meet others and become good friends and help each other with layout and model projects.  Modelers are welcome to participate in these activities while considering NMRA membership.   NMRA membership includes local division, region and communications as well as the monthly NMRA Magazine.

Membership in the NMRA is not required to be a member of O Scale Central.
