However, the DOT was more interested in "really" high speed trains, and had been funding several developments along these lines for some time. In order to expedite these developments, they had recently selected a parcel of land outside Pueblo, Colorado as a test site that would become the Transportation Technology Center (TTC). They planned on using the TTC to lower the cost of all-up testing of advanced designs, as well as guaranteeing that all the participants would have a level playing field. Several U.S. companies were in the process of building hovertrain systems based on technology licensed from the French Aérotrain project, known under the U.S. term "Tracked Air-Cushion Vehicle", or "TACV", and these were in the process of being set up at the TTC.
