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 at 1818 E. Winsett St. Suite A (next to Phil's Tires) Tucson, AZ 85719.


The club's layout includes the HO standard gauge Tucson and South Western Railroad, and the narrow gauge HOn3 Crown King and McNary Railroad. Both the standard gauge and narrow gauge layouts operate on DCC, currently a wireless NCE system.


SASME is a 501c3 non-profit organization promoting model railroad building, operating, and education in a relaxed social setting.


Visitors are welcome at any of our meetings or operating sessions.
