State of the Art Car (SOAC) is a heavy rail mass transit demonstrator vehicle that was promoted by the United States Department of Transportation's Urban Mass Transportation Administration's (UMTA) Division in the mid 1970s. A two car demonstrator was built by St. Louis Car Company (after winning bid over Budd Company, Pullman-Standard, Rohr Industries, and Vought Aeronautics) based on the R44 subway car for New York City and toured five American cities with subway systems: These were the very last railcars produced the venerable St. Louis Car Company, using the two remaining R44 subway car shells produced before they ceased operations in early 1974. The five American cities toured were as follows; * Boston – August 1974 (MBTA South Shore Red Line and Cambridge-Dorchester Line) * Chicago – January 1975 (Skokie Swift line) * Cleveland – (CTS Airport line) * New York – April 1974 (NYCTA Eighth Avenue–Fulton Street A, Concourse–Sixth Avenue–Brighton D, Queens Boulevard–Eighth Avenue E and Queens Boulevard–Broadway–Sea Beach N services)〔nycsubway.org—(Major Line Closures )〕 * Philadelphia – late 1974 (SEPTA Broad St. Subway),〔(【引用サイトリンク】title=SOAC At Pattison Station )〕 August 1976 (PATCO Speedline to Lindenwold, New Jersey)〔(【引用サイトリンク】title=Chicago ''L''.org: Car Roster - State-of-the-Art Cars )〕 While the cars were well received, the concept did not catch on and was retired. Since this experiment, all future rapid transit cars were designed by manufacturers with input with clients and the USDOT stopped R&D work on public transit concepts. This was also the UMTA's one size fits all approach to rapid transit car design that did not fare well with many transit operators, since many systems could not accommodate 75' foot or 10'-6" wide subway equipment due to clearance issues. The two car demonstrator is now owned by the Seashore Trolley Museum in Kennebunkport, Maine, and is currently a static display. ==See also== * US Standard Light Rail Vehicle * Bay Area Rapid Transit A and B rolling stock share similarities with SOAC * Intermediate Capacity Transit System - a smaller system developed by the Urban Transportation Development Corporation in the mid 1970s in Canada * LRC - heavy rail car design by Bombardier Transportation in the 1970s and used by Via Rail in Canada from the 1980s and 1990s. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「State of the Art Car」の詳細全文を読む スポンサード リンク
