On October 29, 2012, another full closure was ordered before the arrival of Hurricane Sandy. All services on the subway, the Long Island Rail Road and Metro-North were gradually shut down that day at 7:00 P.M., to protect passengers, employees and equipment from the coming storm. The storm caused serious damage to the system, especially the IND Rockaway Line, upon which many sections between Howard Beach–JFK Airport and Hammels Wye on the Rockaway Peninsula were heavily damaged, leaving it essentially isolated from the rest of the system. This required the NYCTA to truck in 20 R32 subway cars to the line to provide some interim service (temporarily designated the ). Also, several of the system's tunnels under the East River were flooded by the storm surge. South Ferry suffered serious water damage and did not reopen until April 4, 2013 by restoring service to the older loop-configured station that had been replaced in 2009; the stub-end terminal tracks remained out of service until June 2017.
