Layout Change Request

We have a Layout Change Request for members' consideration. We would normally present it at a Business Meeting, but in light of these unusual times, it is posted at the link below, for your review. It will be an agenda item for vote, likely at the July Business Meeting. 


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 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 on Wednesday at the club's building. 


Business Meeting -- the first Wednesday of each month at 6:30 PM. 


Work Night -- is dedicated to layout work. Members often arrive by 3:00 PM; the quitting time varies.


Run What You Brung -- is for the open running of trains. Members often arrive by 2:00 PM; the quitting time varies.

Prototype Operations -- is standard gauge prototype operations night.
  • 2:00 PM - track cleaning
  • 2:45 PM - jobs start
  • 3:00 PM - trains begin running
  • 4:30 PM - break for dinner
  • 6:00 PM - resume operations
