New York: The New York commuter train which derailed at the weekend leaving four people dead was travelling at nearly three times the recommended speed limit when it hurtled off the tracks, federal investigators have said.
National Transportation Safety Board member Earl Weener said the train involved in Sunday`s accident in the Bronx had clocked 82 miles (131 kilometers) per hour as it entered a curve where the limit was 30 miles (48 kilometers) per hour.
"Preliminary information, from the event recorders, shows that the train was traveling at approximately 82 miles per hour as it went into a 30 mile an hour curve," Weener said.
Investigators also found that shortly before the crash the train`s throttle had gone to idle and there had been a sudden loss in brake pressure.
"Our investigators will be carefully reviewing all the data to determine the functioning of the brakes throughout the trip and to determine why the throttle went to zero, brake pressure went to zero," Weener said.
"At this point, we are not aware of any problems or anomalies with the brakes."
The train, carrying between 100 and 150 people, crashed at around 7:20 am (1220 GMT) Sunday as it headed south to Grand Central Station in Manhattan.
The train`s seven cars derailed just before it reached Spuyten Duyvil station and flew across a grassy bank separating the railroad from the Hudson and Harlem rivers, which meet at that point.
The front car came to rest only a few feet from the water and two cars toppled on their side.
Weener said investigators had begun questioning the driver and would continue to do so over the coming days.
New York Governor Andrew Cuomo said earlier yesterday the cause of the crash, which also left 67 people injured, was most likely "speed-related," noting that the stretch of track involved in the accident was "tricky" but not especially hazardous.
"This was a tricky turn on the system, but it`s a turn that`s been here for decades and trains negotiate all day long," he told NBC.
"I think it`s going to turn out to be about the speed more than anything, and the operator`s operation of the train at that time."
Cuomo later described the horror passengers experienced as the train skidded at high speed before coming to a rest.
"The windows broke out, the doors opened and they were picking up stones, rock, dirt, tree limbs were flying through the cars," he said.
