The power is out at Grand Central Terminal, but trains are still running.
Before 9:30 a.m. Monday, a 6-inch diameter water pipe burst, flooding a transformer house that feeds power to the station, according to MTA spokesperson Aaron Donovan. Eighteen inches of water resulted in total loss of power to the terminal, he said.
Generators partially restored electricity to the terminal, but the lower level and some other hallways and corridors are still dark.
Trains that run out of the lower level have been diverted to the upper level, and because of the reduced holiday schedule, service has not been affected.
"It's a weekend holiday schedule so we have no capacity issues," Donovan said. "It would have been a problem if it happened during rush-hour."
Power was also lost to about 100 stores in ther terminal, he added.
Electronic ticketing machines were not working, and the MTA said passengers could buy tickets on board without paying additional fees.
It was not immediately clear when the power would be fully restored.
Loreta Carrero, 44, works as the florist manager of the Eli Zabar's store in Grand Central. She was arranging flowers when the lights went out.
"We just all turned around and we immediately lost power, just like that," she said, hanging around outside the market hours later. "You get a little nervous. It was dark. It was a little spooky."
