Rocky Mountain Train Show — Spring 2026

The Rocky Mountain Train Show is the premier train show event in the Mountain West region. Held twice yearly at Denver's National Western Complex, the spring show draws thousands of modelers from Colorado and surrounding states. The show floor features dozens of operating layouts showcasing the dramatic mountain scenery that defines Western railroading. The vendor hall is one of the largest in the region, with dealers offering everything from brass locomotives to scenery supplies. The swap meet area sees brisk trading as collectors buy, sell, and trade. Colorado's active model railroad community turns out in force, making this an excellent place to connect with local clubs and modelers.
