What does operations have to do with prototype modeling? Lonnie Bathurst, organizer of the St. Louis Railroad Prototype Modelers (RPM) Meet, and Rick Watson, President of the Operations Special Interest Group (OPSIG), stop by the ATLP studio for a deep dive into the 2026 St. Louis RPM. This year, the nation's largest RPM meet puts the spotlight on “Operation - The Key to Modeling Your Prototype.” The panel explores how prototypical operations enhance realism, modeling, community, and the next generation of railroad hobbyists and how both organizations combined to teach the community how they can bring both aspects together.
