In 1993, streetcar service returned to Memphis after a hiatus of a half century.  Restored trolleys from Rio de Janiero, Brazil, Melbourne, Australia, and Tampa, Florida take visitors throughout downtown and along the riverfront.  At the intersection of Main and Beale stands a Memphis treasure, the Orpheum Theatre, one of the last remaining movie palaces from the 1920s.    An extensive restoration completed in 1984 brought the 2,400 seat theater back to its former opulence for concerts, Broadway productions, and films.
