The head of the Metropolitan Transportation Authority warns that subway tubes flooded during Hurricane Sandy likely still need repairs on equipment damaged by saltwater.
The closed R train tube in the East River that connects Brooklyn to Manhattan could be out of service for more than a year, while one linking Brooklyn and Queens on the G line has been shut for repairs on weekends this summer.
Seven other underwater tubes damaged less severely by the storm need work, too, though the extent of the work is not yet known.
"We know there's problems in the other tubes, but we really can't deal with those until we deal with these, because you can't close or limit capacity in too many tubes at one time. Otherwise, you actually reduce the level of service," said MTA Chairman Thomas Prendergast.
The G tube faces four more weekend closures this year, while the MTA hopes to have full R service by October 2014.
