Hit The Brakes!
Some in DC are considering allowing 20% heavier trucks on our roads – even allowing triple trailer trucks. 97,000 pound trucks speeding down our highways will tear up our roads and cost taxpayers even more in road and bridge repair. Check out the website here.

Go to Tracks
There are 48 miles of railroad track available for testing locomotives, vehicles, track components, and signaling devices at the Transportation Technology Center (TTC), Pueblo, Colorado. Specialized tracks are used to evaluate vehicle stability, safety, endurance, reliability, and ride comfort. Using TTC's tracks eliminates the interferences, delays, and safety issues encountered on an operating rail system.

Green Engineering is defined by the US Environmental Protection Agency as "the design, commercialization, and use of processes and products, which are feasible and economical while minimizing risks to human health and the environment." One related effort undertaken by TTCI engineers has focused on gradually automating the train operations at FAST.

Go To Laboratories
TTCI's assets set it apart from other research and testing facilities. One-of-a-kind test machines provide TTCI engineers with the tools to test and evaluate railroad products and/or improvement concepts. Computer models, designed to predict railroad equipment performance, help TTCI provide clients with a look at proposed designs prior to prototype fabrication.

Go To Transportation Security
One way or another, we are all working to assure our security. Rail freight and passenger transportation systems are working around the clock to protect citizens, infrastructure, and services. Sabotage detection and prevention is now a critical arena for research and development.
