peak and midday and Saturday daytime, South Ferry to Astoria weekday PM peak, 57th Street to Astoria evenings and Sundays. Midday and Saturday trains used the express tracks, weekday peak trains made all stops. On April 23, 1939 express service was inaugurated weekday and Saturday daytime in Queens between Queensboro Plaza and 111th Street, where elevated trains were cut back to. On September 8, 1939 Astoria trains were rerouted in the weekday PM peak to City Hall. The Second Avenue Elevated was closed north of 59th Street June 12, 1940. Evening and Sunday Queens trains were extended to City Hall or South Ferry. On May 19, 1941 evening and Sunday service was discontinued. Finally, on June 13, 1942 all service was discontinued. The M15 bus, which runs along much of the IRT Second Avenue Elevated Line's route, is one of the busiest bus routes in New York City. However, it does not carry as many passengers as a rapid transit line, and transfers to rapid transit stations can only be made using surface connections. The Second Avenue Subway, a rapid transit route running under Second Avenue, has been under consideration since 1919. The demolition of the IRT Second Avenue Line was in anticipation of the subway's construction. The first phase, between 72nd Street and 96th Street, opened in 2017, and a second phase to Harlem–125th Street is being planned.
