Updates on Service Restoration in New York City BEACH CLEANUP Removing debris from the shoreline in the Rockaways on Thursday. About 80,000 customers were without power as of late Thursday afternoon, mostly in Queens. The situation was particularly dire on the Rockaway Peninsula, where nearly 40,000 customers remained without power, the Long Island Power Authority reported on its Web site. The authority, which serves the area and has been among the most criticized of the region's electricity providers since Hurricane Sandy hit, reported on the site that it had about 240 linemen and tree trimmers in the area, but did not estimate when power would be fully restored. In other parts of Queens, more than 22,000 customers did not have power, Consolidated Edison reported, with nearly half of those in Jamaica. About 3,500 remained in the dark on Staten Island. Con Edison said it expected to restore power fully throughout the city by the end of Sunday. Space was available in the city's seven shelters, where about 2,750 people remained as of Thursday, officials reported. Four more shelters were available for people with special medical needs. The city was also providing blankets, food and heated space for daytime use at various locations, as well as centers where people can apply for temporary cash assistance and other services. Crews were working to repair 43 schools that were closed because of structural damage, and 13 more schools remained without power, officials said. About 26,000 students have relocated to other schools. An estimated 28 schools were open without heat. The Queens-Midtown Tunnel will reopen in time for the morning commute on Friday. The Brooklyn-Battery Tunnel remains closed. The city instituted gas rationing beginning on Friday as fuel shortages and long gas lines continued across the city, a situation Mayor Michael R. Bloomberg said could persist for several more weeks. Subway service is operating normally on most lines with some service changes. Service on the L train between Brooklyn and Manhattan was restored on Thursday. Service remains suspended on the N train between 59th Street and Coney Island in Brooklyn, on the A in Far Rockaway, on the S Rockaway Park Shuttle, on the 1 train between Chambers Street and South Ferry, on the R between Manhattan and Brooklyn and on the J between Chambers and Broad Streets. Metropolitan Transportation Authority officials did not estimate when they would be restored.
