| San Francisco on
      the west coast of America has an impressive heritage streetcar
      service.   Called the F-Line, the route stretches for six miles
      and is served by around 30 vintage trams.   The trams are mainly
      former San Francisco streetcars dating from the 1940's painted in the
      colours of USA cities that operated them.   Also present are ten
      trams originating from Milan painted in the famous orange livery of that
      city, and some trams from around the world such as Melbourne and Blackpool. |
