SMR is an association of model railroad enthusiasts, incorporated under the laws of the State of North Carolina, as a non-profit, educational, and historical association. In addition to maintaining and operating the main layout in the Clubhouse, SMR engages in other activities, including train shows, open-houses, support and maintenance of Brenner Children's Hospital Layout, Involvement in School, Scout & Senior activities, instructional clinics for members, and occasional field trips to observe prototype railroading operations.  Work nights are held every Tuesday evening, with regular business meetings on the third Tuesday of each month at 7:00pm.

Initially formed in 1973, the Club built a portable layout.  After finding permanent quarters, a large layout was constructed and operated for many years at the Nature Science Center.  During this time, the Club chartered and operated several steam excursions originating in Winston-Salem, and traveling to Asheville, Roanoke, Lynchburg, and North Wilkesboro, bringing every steam locomotive in the Southern steam program to Winston-Salem.  Many of our early members are still active after 35 years.  While current members are indebted to their predecessors, for their vision, creativity, and dedication in providing the opportunity for participation in SMR, the train has yet to reach its destination. The future of the Club is now up to the "mix" of both old-timers, and new members, as we continue down the track.

The club has a portable HO switching layout, which can be quickly set up at a remote location, is used for publicity purposes.  In addition, the Club meeting room includes an extensive model railroading library, including periodicals, books, and videos.

Southbound Model Railroaders maintain a close relationship with the Winston-Salem Chapter of the National Railroad Historical Society (NRHS), which meets in our building.
