Texas Transportation Museum

The Texas Transportation Museum (TTM) is a transportation museum located in San Antonio, Texas.

It was created in 1964 to help preserve artifacts and information about San Antonio's transportation history. TTM operates as much of its collection as possible, including many railroad vehicles on its own heritage railroad, the Longhorn and Western Railroad, multiple model train layouts, and many antique automobiles. TTM's goal is to provide an educational and entertaining experience which interprets how developments in transportation technology shaped and continue to impact daily life.

The museum hosts three major events annually, an Easter egg hunt in April for Easter, "Spook-Track-Ula" in October for Halloween, and "Santa's Railroad Wonderland" in December for Christmas. High school Cross Country running races starting from the adjacent North East ISD Sports Park run through the property as well.

Different areas, including a remodeled caboose, picnic tables, children's play area and a large outdoor pavilion can be rented for group parties. The children's play area includes a playscape consisting of a wooden steam engine and a metal scale-model diesel engine.

TTM is a registered 501(c)(3) charitable organization.
