NEW YORK –  The misery of superstorm Sandy’s devastation grew Tuesday as millions along the U.S. East Coast faced life without power or mass transit for days, and huge swaths of New York City remained eerily quiet. The U.S. death toll climbed to at least 55, many of the victims killed by falling trees, and rescue work continued.

The storm that made landfall in New Jersey on Monday evening with hurricane force cut power to more than 8.2 million across the East and put the presidential campaign on hold just one week before Election Day.

New York was among the hardest hit, with its financial heart closed for a second day. The storm caused the worst damage in the 108-year history of the city’s subway system, and New York City Mayor Michael Bloomberg said it could be four or five days before the biggest U.S. transit system was running again.

“This was a devastating storm, maybe the worst that we have ever experienced,” Bloomberg said.
