The 37th National Narrow Gauge Convention will take place August 30th through September 2nd 2017 in Denver, Colorado – Always a fan favorite narrow gauge convention location. The convention will be held in The Marriott Denver Tech Center. Our narrow gauge convention is sure to please: clinics on narrow gauge prototypes and modeling from across the world, loads of contest models, two full vendor’s rooms, spectacular modular layouts, and much more. Did I mention we have a lot of trains you can ride? Our committee has brokered special discount admission prices on all the major railroading attractions in our state. We have numerous layout tours that will take place before, throughout and after the convention days, We’ll send updates on these after you register for the convention.
