(Photo by William C. Vantuono) Management of the Pueblo, Colo.-based Transportation Technology Center (TTC) will move to a new vendor as of October 2022. More than 50 miles of railroad track and specialized laboratories for testing locomotives, vehicles, track components and communications and signaling devices in the Colorado desert outside of Pueblo comprise the TTC, which is owned by the Federal Railroad Administration (FRA). Since 1982, the Association of American Railroads (AAR) has managed the TTC, most of that time through Transportation Technology Center, Inc. (TTCI), its wholly owned subsidiary. TTCI has held successive single-source Care, Custody and Control Contracts signed with the Federal Railroad Administration (FRA).
