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.

Membership and Layout Tours

The club is open to new members, layout tours and just stopping by to say hi. 

Visitors are encouraged to stop by during Prototype Operations or Open Running. See Coming Events for the days and times. Business Meetings and Work Nights are open to visitors, as well, just less likely to have any trains running. We are happy to show you around and talk trains.

If you cannot make one of the official meeting times, contact us and we will try to accommodate a tour at a more-comvenient time. Click here or on the "Contact Us" link above to access our email form.  

Anyone interested in membership is encouraged to visit the club, get to know us, then submit an application. The details are available in the "SASME Bylaws" on the "Resources" page link above.
