Lower Manhattan has been hardest-hit, he says. It could take just 14 hours to pump out the water—or it could take four days, officials say. And that's just the beginning: Salt water damage could require teams to replace vast amounts of equipment. "We’ve got the materials and the wherewithal necessary to repair whatever damage there is as quickly as possible," says the MTA chairman. But there's simply no timetable as to when service will resume, CBS News reports. Boston's transit authority, meanwhile, expected subway service to come back online this morning, reports the Globe.
