***Now Departing Memorial City Station*** Last Call for HTOS! Due to renovations taking place at Memorial City Mall in June of 2026, our last "open to the public" run date is tentatively Tuesday, March 31st, 2026. We are grateful to Memorial City Mall to have been blessed with the opportunity to provide multiple "free to the public" operating model train displays for over 20 years. We will miss our regular visitors but plan to find a new home where we can continue our goal of promoting the hobby that we love.

HTOS What We Do

Visit HTOS and relive the excitement and wonder of model railroading.

The Houston Tinplate Operators Society (HTOS) was founded in 1988 by a group of model train enthusiasts who wanted to have fun running Lionel O-gauge and compatible trains. Our members' interests range from true tinplate (pre & postwar) to near-scale 3-rail operation. HTOS is dedicated to promoting the history of 3-rail O-gauge trains and fostering the education of people in the field of model railroading.

The front of our club location is pictured at left, a year-round permanent location. HTOS is one of the few O-Guage train clubs in the state of Texas.

The club operates four layouts in our space. The large portable layout, a 'seasonal' window layout, a larger permanent window layout, and an American Flyer S-Gauge layout are for public viewing. There is also a hands-on kids wooden train layout. Enjoy!
