2023 RGM&HS Convention in Denver, Colorado

Mark your calendars for our 2023 convention which will be in Denver, Colorado on August 27-30, 2023, and will run sequentially with the 2023 National Narrow Gauge convention which will run August 30th – September 02, 2023.

Our 2023 RGM&HS Convention will be held at the DoubleTree by Hilton Denver – Aurora, which is short distance from the hotel hosting the Narrow Gauge convention. So its the perfect opportunities to take in both events while in Denver.

Currently we are working on a great line-up of programs for the 2023 that will include color photography and explanations of Rio Grande Standard and Narrow gauge operations.   The programs we are considering will cover both freight and passenger operations on the D&RGW system. The full list of programs, other convention events being planned is forthcoming. Please check back here for more updates.

Registration is already open for the National Narrow Gauge Convention and we encourage folks to consider attending both events.  To learn more about the 43rd National Narrow Gauge Convention in Denver click here
