The State-of-the-Art Car (SOAC) was a heavy rail mass transit demonstrator vehicle produced for the United States Department of Transportation's Urban Mass Transportation Administration in the 1970s. It was intended to demonstrate the latest technologies to operating agencies and the riding public, and serve to promote existing and proposed transit lines. A single married pair was produced by the St. Louis Car Company in 1972. It operated in intermittent revenue service on six rapid transit systems in five United States cities between May 1974 and January 1977. Since 1989, the two cars have been on display at the Seashore Trolley Museum in Kennebunkport, Maine.
