Union Switch & Signal
Evolution of a Pittsburgh company:
For 125 years, Union Switch & Signal has set the pace for the industry in the development of reliable signaling and train control, wayside equipment and relays. US&S: design, manufacture and service of signaling, automation and control equipment for the railroad and mass transit industries worldwide. The company still has its headquarters in Pittsburgh, Pennsylvania.
George Westinghouse founded Union Switch & Signal in 1881, consolidating the assets of companies that had pioneered closed track circuits and interlockings. Operating as an independent company until 1917, US&S became a subsidiary of Westinghouse Air Brake. In 1968, American Standard purchased the entire operation and reorganized US&S as a separate division. In 1988, Ansaldo purchased US&S from American Standard. In December 1996, US&S merged with the other signaling investments of Ansaldo located around the world. As a result of that merger, US&S is now a wholly-owned subsidiary of Ansaldo Signal, a global supplier. Company headquarters are still located in Pittsburgh.
