Streetcars "are as dead as sailing ships," said Mayor Fiorello LaGuardia in a radio speech, two days before Madison Avenue's streetcars yielded to buses. LaGuardia was determined to eliminate streetcars, demolish pre-1900 elevated lines, and unify the subway system, a goal that became reality in 1940 when the separate IRT, BMT, and IND became one giant system under full public control.
