The Central Missouri Chapter was established in 1995 in the Columbia, Missouri area.
The Central Missouri Chapter is located in Columbia, MO. Meetings are held the first Wednesday of every month at 7 PM at the clubhouse located in the basement of the home located at Rock Quarry Park off Grindstone Parkway. The club has built a set of O gauge modules that are normally set up at the clubhouse. The modules are moved and set up for an annual show for the City Parks and Recreation Department in the spring, and for the Chapter annual swap meet in the fall.
Monthly meetings usually involve possible work on the modules, running O gauge trains on the modules, and a business meeting.
