[article] NEW YORK – At least four people are dead after a Metro-North passenger train derailed on its way to New York City, sources tell FoxNews.com. There are "dozens of injuries” in the accident that occurred at 7:20 a.m., about 100 feet north of the Spuyten Duyvil station in the Bronx, according to Metro-North. A Metro-North spokesman tells FoxNews.com the derailment involved the commuter train departing Poughkeepsie in Dutchess County at 5:54 a.m. -- the second train to leave that station on Sunday. The derailed train was due to arrive at Manhattan’s Grand Central Station at 7:43 a.m. The whole train comprised seven cars, plus a diesel locomotive, and five of the cars went off the tracks, said Metro-North spokesman Aaron Donovan. The derailment occurred near the Harlem River, and authorities say two cars were left lying on their sides, although none of the cars went into the nearby waterway. “One approached the water and came close, but did not go in,” Donovan tells FoxNews.com. Donovan said a locomotive was pushing the train from behind, although the operating engineer who controlled the train was stationed in the front of the first passenger car. “It’s going to be a long time before this is cleared up,” MTA spokeswoman Marjorie Anders told Fox News. “It was not a hugely crowded train,” she added. It is unknown as-of-yet what caused the derailment, officials told FoxNews.com. Sources told FoxNews.com as many as four people died in the accident, although that number was unconfirmed shortly before 10 a.m.
