The Transportation Technology Center, or TTC, is a railroad testing and training facility located northeast of Pueblo, Colorado. It originated as the Department of Transportation's High Speed Ground Test Center as a site to test several hovertrain concepts. When those projects were completed in the 1970s, the site was handed to the Federal Railroad Administration,[1] who, in turn, turned over operations to the Transportation Technology Center, Inc., a wholly owned subsidiary of the Association of American Railroads (AAR). The site is home to numerous test tracks and laboratories.[2]
