O Scale National Convention Returning to Denver
Welcome to the website for the O Scale National Convention in Denver, to be held June 8-11, 2023.
This convention will include internationally acclaimed clinics, impressive layouts, the trading hall, and area rail attractions.
We will have brand new clinics at the convention, such as exploring 3D printing details, modeling skills by Sarah Griessenböck, modeling the Exposition Flyer passenger train by Santiago Pineda, updating locomotive drives, layout space planning for O Scale, and so much more!
O Scale layouts will be open including David Stewart’s legendary Appalachian & Ohio and Jeff MacDonald’s beautiful High Plains Route. Check out our Layout Tours page for more information!
Registration for OSNC couldn’t be easier! The Registrations tab includes links to register for the convention, a direct link to book with the Hyatt Regency in Aurora, and a print and mail-in application for those who prefer that option.
Denver is an important railroad city, and there are so many attractions to see in the area. Our Interactive Map will help you plan your visit. There are also many attractions on the way to or from Denver if you are driving.
There are plenty of tourist railroads, museums, and railfanning opportunities in the area. The Railfanning and Museums tab has all the information on area attractions.
Denver is a very well-connected city. The Transportation tab has all sorts of information on how to get to and from the Mile-High City! Amtrak train service is available from many locations.
The Trading Hall space has over 100 tables for new and second-hand models, representing 70 years of O Scale, as well as the newest modeling products out there. You will not want to miss for that alone!
Models for display are invited and evaluation of contest models is planned using NMRA criteria.
Registration and table fees are the same as 2021 and the Hyatt Regency, Aurora, CO will be our headquarters. Please stay with the Hyatt Regency using our special rate to help the convention.
