Four killed, 63 injured in New York train derailment
The crash happened at 7:20 am (1220 GMT) about 100 metres north of Metro North's Spuyten Duyvil station in the city's Bronx borough, said Metro North spokesman Aaron Donovan.
A Fire Department spokesman confirmed the number of dead and said 11 people were in a critical condition, six were in serious condition with non-life threatening injuries and another 46 suffered minor injuries.
The train, headed south toward Manhattan's Grand Central Terminal, was about half full at the time of the crash with around 150 passengers, said the state's Metropolitan Transportation Authority (MTA), parent company of Metro North.
"On a workday, fully occupied, it would have been a tremendous disaster," New York City Fire Commissioner Salvatore Joseph Cassano told reporters at the scene.
At least one rail car was lying toppled near water in an area where the Hudson and Harlem rivers meet. Other cars were lying on their sides.
There is no official word yet on the possible causes of the accident.
Passenger Frank Tatulli told television station WABC he had been riding in the first car and that the train had been traveling "a lot faster" than usual.
"The guy was going real fast on the turns and I just didn't know why because we were making good time and all of a sudden we derailed on the turn," he said.
Joseph Bruno, who heads the city's Office of Emergency Management, told CNN it appeared that three of the four people killed had been thrown from the train. The MTA and the fire department both said that could not immediately be confirmed.
Michael Keaveney, 22, a security worker whose home overlooks the site, said he had heard a loud bang when the train derailed.
"It woke me up from my sleep," he said. "It looked like (the train) took out a lot of trees on its way over toward the water."
A Metro-North passenger train has derailed in the Bronx area of New York City, with reports of at least 4 deaths and at least 48 injured, according to reports from NBC.
UPDATE: NY Governor gives a press conference regarding accident
New York Governor Andrew Cuomo has given a press conference at the crash site.
He described the derailment was a "tragic incident".
He said: "Four people lost their lives today in the holiday season and their families are in our thoughts."
He added that the 11 passengers believed to be critically injured were in a "serious but stable" condition.
Governor Cuomo said he believed everybody had been accounted for, including the train operator, who was alive and being cared for.
He said those who had been killed were travelling in the two carriages in the middle of the train, which had turned completely on their side.
Meanwhile the New York Fire Department's chief of department Edward Kilduff has confirmed that three of the four fatalities were found outside the train.
He said: "We believe three of the four fatalities were thrown out of the train as it was twisting and turning on the track."
He added that none of the bodies were found in the water.
Chief Kilduff said the scene had been searched "several times over" and he believed everyone on the train was accounted for.
However, he said they still did not know exactly how many people were on the train when it derailed.
Injured toll rises to 67, 11 in critical condition - FDNY
Senior New York Fire department officials told NBC, four people have died and as many as 67 people have been hurt, including 11 who are in a critical condition.
Divers have gone into the water to search for victims, who may have been thrown from the train.
Metropolitan Transportation Authority police say the train derailed near the Spuyten Duyvil station just after 7.20am.
Pictures showed five carriages lying on their side, with one inches from the Hudson river.
The derailed train was the 05:54 service from Poughkeepsie, in upstate New York, which was due to arrive at Grand Central Station in Manhattan at 07:43.
It left the tracks in the Spuyten Duyvil section of the Bronx. The area, whose name translates from the Dutch to "Spitting Devil", is known for its difficult curved section of railway line and was the scene of a 10-carriage garbage train derailment only four months ago.
The fire department says 130 firefighters are on the scene.
At least two died, a New York City police source familiar with the investigation and rescue told CNN
Reports are emerging that 30 people have been injured following the derailment in the Bronx, but this information has not yet been confirmed.
A passenger who was on the train, Frank Tatulli, told Eyewitness News he takes the train every Sunday morning, and that it was travelling at a higher rate of speed than it normally does.
Tatulli said he got out of the train on his own, and suffered head and neck injuries.
The train was heading towards Grand Central Station, when it came off the tracks on what has been described as a "problem curve" on the line.
Accordig to RT, Rebecca Schwartz, a witness at the scene, told the AP news agency that some of the carriages were submerged in water and that numerous emergency vehicles were at the scene.
There is no information yet on how many people were travelling on the train.
The derailment happened just north of Manhattan on Sunday morning. According to ABC, the train was the 5:54 from Poughkeepsie to Grand Central and was due to arrive into Grand Central at 07:43.
The line involved in the accident serves Metro-North’s Hudson line, which serves dormer towns like Croton-Harmon, Peekskill, Ossining and Yonkers.
Metro-North tweeted: "Hudson Line Srvc is currently suspnded south of Crotonharmon due to train incident at Spuyten Duyvil More info will be provided as we get it"
Spuyten Duyvil is a neighborhood in the Bronx. Metro-North's Hudson line serves New York City and Westchester, Putnam, and Dutchess counties, ending in Poughkeepsie.
The Metro-North noted the incident on its website with a note that "Hudson Line Customers will experience indefinite delays south of Croton Harmon. More information will be provided as it is obtained."
