At least three people were killed and scores of others were transported to hospital when an Amtrak train derailed south of Seattle at 7:40 a.m. Monday.
There were 72 passengers aboard the train who were evaluated for injury, Washington State Police Capt. Dan Hall, said Monday night. Ten of the passengers were said to be in serious condition while 13 others were left with moderate or minor injuries.
The NTSB took over the investigation on Monday night from Washington State Police and the FBI.
Officials with the NTSB said Monday night that the train was travelling at 80 miles per hour in a zone where the limit was 30 miles per hour.
Earlier media reports had said there were six killed, but officials couldn’t confirmed that number.
While officials couldn’t confirm if all passengers had been accounted for, fire officials said they had searched all the train cars for survivors.
Nearby Madigan Hospital received 20 patients. King5 reports nine people are in serious but stable condition and 11 people are in “fair” and stable condition.
WATCH: ‘We need EMS ASAP’: conductor tells dispatcher following Amtrak train derailment
Eighty passengers and five crew members were on board the train when it derailed. Amtrak raised the number of passengers aboard Monday evening as two employees were on the train but were on employee passes.
The train was made up of 12 cars and two engines. Thirteen of those cars jumped the track.
One of the cars contained diesel fuel. At its maximum the car could hold 350 gallons of fuel, but officials couldn’t confirm if it was full.
This was Amtrak Train 501, which is a new service starting today running from Seattle to Portland. The train was on its inaugural trip.
The engines were equipped with positive train control – the technology that can slow or stop a speeding train – but it wasn’t in use on this stretch of track, according to Amtrak President Richard Anderson.
Anderson said he was “deeply saddened by all that has happened today,” during a conference call with reporters on Monday.
Radio transmissions from the train just moments after the derailment have now been released.
“Emergency, emergency, emergency, we are on the ground,” one of the crew members can be heard saying. “We need EMS ASAP, it looks like they’re already starting to show up.”
When asked what happened, the crew members says “we were coming around the corner to take the bridge over I-5 there, right north into Nisqually and we went on the ground.”
“We’ve got cars everywhere and even down on to the highway.”
Chris Karnes was a passenger on the train when the incident happened.
“All of a sudden we were slammed into the seats in front of us and then the car careened down an embankment,” he said. “We could hear and feel the cars crumbling and breaking apart. There was a lot of dust all over the place.”
He said they had to kick out the emergency window because the emergency doors were not functioning. “Multiple people injured,” he said. “Cuts, people bleeding, I did see one person laying on the ground who was not moving.”
A person who witnessed the crash said it happened so fast.
“It just jumped the curb and ‘bam,'” one witness told King5. She said the train went off the track just as it curves.

It is unclear exactly how the train derailed but reports state the train hit a truck. The train was reportedly travelling 130 km/h at the time of the derailment but it can go much faster.
According to The Associated Press, the maximum speed along that stretch, which is known as Point Defiance Bypass, is 79 mph, or about 127 km/h. This is according to information about the project posted online by the Washington State Department of Transportation.
Witness Chris Karnes was on the train and he spoke to CBS News Monday morning saying they had just passed the city of DuPont, which is between Tacoma and Olympia.
“At a certain point it seemed we were reaching a sort of a bend in the tracks and all of a sudden we were slammed into the seats in front of us, and then the car careened down an embankment,” he said.
I-5 southbound is closed at the Mounts Road overpass, with one lane northbound also closed.
The Washington State Department of Transportation is warning everyone to avoid the area and restrict travel if possible.
Amtrak service south of Seattle is temporarily suspended. Service from Seattle to points north and east is continuing to operate. Amtrak Cascades 504 and 509 are cancelled.
