U. S. Federal Transportation Administration Buy America provisions ensure that transportation infrastructure projects are built with American-made products. That means that Federal Transportation Administration investments are able to support an entire supply chain of American companies and their employees. SUTRAK became a supplier that meets buy America rules in 1981 when the company set up manufacturing facilities in Lamar, Colorado. Nearly 30,000 units have been produced to date that meet the Buy America regulations supporting as many as 220 U.S. manufacturing jobs at any given time.
