1967The Rio Grande Modeling & Historical Society (RGM&HS) found in 2001 is an Colorado non-profit corporation whose membership consists of diverse group of historians, collectors, railfans, photographers, modelers and railroad employees who have banded together to share one common interest, the Denver & Rio Grande Western Railroad and its predecessors. The fellowship created by this common interest and the opportunity for networking with members and others are the society's greatest assets. Activities to promote this fellowship are geared to serve the wide variety of interests of its members on almost every facet of the D&RGW as it served as the "Action Road"

The mission of the Rio Grande Modeling & Historical Society is to preserve and disseminate historical information about the Denver & Rio Grande Western Railroad for the benefit of our members and to others by locating, gathering, preserving, interpreting tangible items relating to the D&RGW and distributing information, documents, publications thus promoting fellowship and education among persons with interests in the railroad.

The RGM&HS depends heavily upon its members to provide support for the group through their willingness to contribute in any way possible. Those with experience in any phase of publishing, drafting, have knowledge of the operation of the D&RGW, or have collections of photographs or information are encouraged to offer their assistance.  You can contact us at Membership@rgmhs.org
