About Us



Transportation Technology Center, Inc., is one of two whole owned subsidiaries of the Association of American Railroads. Located Pueblo, Colorado, TTCI is a world-class intermodal research and test center that offers a wide-range of capabilities that are used by freight and passenger railroads from around the world. For example, Amtrak’s high-speed Acela Express trains were extensively tested at TTCI before entering service. Japanese railroads used TTCI facilities to test a gauge changing mechanism. Work at TTCI helped make it possible for freight railroads in the U.S. and Canada to operate freight cars that weigh as much as 286,000 pounds when fully loaded.
