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 HO layout is the Tucson and South Western Railroad, nicknamed The Cactus Route. It interchanges with the Crown King and McNary NGRR, a narrow gauge HOn3 line. 

We meet most Wednesday nights at the club's building. (Check the Coming Events section for the latest information, especially around Wednesday holidays.) 


Business Meeting -- the first Wednesday of each month at 6:30 PM (except December). 


Work Night -- is dedicated to layout work. 

Prototype Operations -- is standard gauge prototype operations night.

Run What You Brung -- is for the open running of trains. 

Narrow Gauge Operations -- is narrow gauge prototype operations.
