in 1906, an electric tram line opened for service between frascati, rome and castelli romani. the trams traveled wholly along tracks laid down on existing streets as an interurban electric streetcar (light rail). in 1954 the electric tram line was replaced by buses. another electric tram service, the rome and fiuggi rail road, called "vicinali", was opened for service in 1916. it connected frascati, monte porzio catone, monte compatri and san cesareo. this tram line was destroyed in 1943 and was replaced by buses.
