The link Marty has listed states the following: "The Transportation Technology Center (TTC) is a world class facility offering a wide range of unique capabilities for research, development, testing, consulting, and training for railway-related technologies. The site, 21 miles northeast of Pueblo, Colorado, is owned by the US Department of Transportation, and is operated and maintained by the Transportation Technology Center, Inc., under a care, custody, and control contract with the Federal Railroad Administration. A 52 square mile facility, TTC is isolated and secure with a vast array of specialized testing facilities and tracks. The site also enables testing of all types of freight and passenger rolling stock, vehicle and track components, and safety devices." I found no link to the TTC.

The TTC is run by the Association of American Railroads. On their site, go to "About TTCI" then "Directions to TTCI". The facility is 21 miles northeast of the Pueblo Airport and due north of the Pueblo Ordnance Depot. The layout of the test track is under "Our Facility" thence "Test Tracks". If you then go to Google Maps click on hybrid and move northeast of the airport and you will see the test track layout very easliy.
