The Southern Arizona Society of Model Engineers

Welcome to SASME

The Southern Arizona Society of Model Engineers -- SASME -- is a model railroad club located in Tucson, Arizona.


We began promoting the hobby of model railroading in 1954. We've had several locations over the years, but in 1984 we moved into our present building. 


The club's layout includes the Tucson and South Western Railroad, nicknamed The Cactus Route and the Crown King and McNary Railroad. The Tucson and South Western (T&SW) is HO standard gauge while the Crown King and McNary (CK&McN) is a narrow gauge HOn3 line.
