Put down your phone and discover Model railroading at the Rocky Mountain Hobby-Expo at the Denver Mart. The model railroading hobby runs the gamut from Thomas the Tank Engine and a train under the Christmas tree to painstakingly detailed layouts that are incredibly realistic. Model railroaders recreate an earlier time and place and connect us with the country’s history in a tangible way. Visit the show for hands-on demos, workshops and great deals!

Model railroading layouts can be made in one of many scales ranging from 1:220 to 1:22.5 of real size that run inside or out in your garden. Model railroaders build skills in carpentry, electronics, painting, and the mechanics of how things work.

You’ll get a chance to meet model railroad manufacturers, see some great club layouts and attend beginner and advanced workshops. Kids can enjoy our kids corner activities as well as participate in our Build-A-Layout program where they work on building a layout that they will have a chance of winning at the end of the show. The Build-A-Layout is sponsored by Bachmann and Woodland Scenic.

Big Modeler News- Meet Tom Daniel at this year’s Hobby-Expo!

Whether you are into cars, trucks, aircraft, military models or figures, visit the show to check out available kits and participate in our plastic model workshops. Scale Model kits vary in material from plastic, to paper, to metal, but always stay true to the ratios and proportions of the object they’re modeled after. You can find kits for aircrafts, automobiles, ships, trains, military, construction sites, buildings, and more!

We’ll have model kit workshops sponsored by the CoMMIES chapter of the International Plastic model Builders Society (IPMS) and Reynolds Advanced Materials. Don’t miss the plastic model Make N Take sponsored by Atlantis Models. CoMMIES will be putting on their fabulous Modeling Live!, where a bunch of club members will be building models – all kinds of subjects, at all stages of build, so people can see it happen and ask questions, and tell us how they built models when they were kids, and realize they could get back into the hobby, share it with their kids and their friends.  

Check out the model displays from Scale Junkiez
