The Presidents' Conference Committee (PCC) is a streetcar design that was first built in the United States in the 1930s. The design proved successful domestically, and after World War II it was licensed for use elsewhere in the world where PCC based cars were made. The PCC car has proved to be a long-lasting icon of streetcar design, and many remain in service around the world.
