Discover what we stand for
We strive to bring you a high quality modeling event, in a professional atmosphere, where modelers may meet, discuss, purchase and learn to make the most high quality models regardless of scale. Models are not judged or graded, but are displayed in a well-lit, free-flowing area where exchange between modelers is encouraged.
Your models are the heart of St. Louis RPM
Bring your models, finished or in progress, for display and discussion. This is a modeler’s event! Bring your models of all scales, gauges, and sizes from all eras. Attendees bring 5,000+ models every year. Bring your models and be part of this annual event. Locomotives, structures, freight cars, dioramas, vehicles are all welcome. Those bringing models are encouraged to download and fill out the various model forms and print them off. It saves time and looks great! There are no contests. The purpose of our event is to teach, learn, collaborate, and meet your fellow modelers from around the nation. See the Photo Gallery for previous years models.
