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 1985 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 each Wednesday night at the club's building at 6:30. 


Business Meeting -- The first Wednesday of each month is the club's business meeting. 


Work Nights -- The second Wednesday is dedicated to layout work. (The third Wednesday is also a work night on months with five Wednesdays.)


Prototype Operations -- The last Wednesday is standard gauge prototype operations night.


Run What You Brung -- The remaining Wednesday each month is for the open running of trains.


Narrow Gauge Operations -- The Tuesday before Run What You Brung is narrow gauge prototype operations night. See the Coming Events for the date or the Railjoiner for more information.
