A Colorado not-for-profit corporation

Our History

The Rio Grande Modeling & Historical Society (RGM&HS) founded 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.

RGM&HS Policy on Supporting Preservation Activities

The Society is frequently approached by preservation organizations looking for the Society’s support on a project.  While most are seeking historical information, some are also looking for financial and volunteer support. The RGM&HS Board discussed these types of requests in our May 2021 BOT meeting and the best ways to support them.  As a result of the conversation a policy was purposed by Mike Carlson and passed by the board detailing how the Society will deal with organizations requesting our help with restoration projects specifically related to the preservation of the D&RGW equipment etc.  The rationale of the policy is to provide fair and equitable attention to all those organization’s project fund-raising activities, in a manner that is sustainable for the RGM&HS with its limited resources.

We see our participation and contribution to these various projects by first providing awareness and sharing information of the projects to our members so they may donate to the restoration project they might desire to support. The RGM&HS will provide at no charge advertising space in either the Green Light, Prospector and or RGMHS website, to those historical preservation societies and or organizations, for the purpose to socializing the restoration of prototypical D&RGW railroad equipment, structures, signs, etc..  The size and frequency of these ads to be determined at the discretion of the Board of Trustees, on a case by case basis.

If you have any questions or comment please feel free to e-mail greenlight@rgmhs.org.
