Amtrak says Northeast Regional Train 188, operating from Washington to New York, left Union Station in Washington, D.C. around 7 p.m., bound for Penn Station when it crashed just before 9:30 p.m. near the 2000 block of Wheatsheaf Lane.
Amtrak officials say there were approximately 238 passengers and five crew members on board when all seven cars derailed.
"This is the Amtrak family, we are very saddened by what has occurred," Anthony Coscia of Amtrak said. Coscia stressed they will work closely with the NTSB and Mayor Michael Nutter's office.

Nutter said the engineer on the train was injured in the crash, but survived and was believed to have given a statement to investigators.
As KYW Newsradio reports, during a news conference Wednesday, Nutter said while the cause of the crash is under investigation, the train's black box was recovered and is being analyzed in Delaware.
On Thursday, as KYW Newsradio reports, National Transportation Safety Board member Robert Sumwalt, who is leading the investigation, says in the wake of preliminary information that the train was running in excess of 100 miles an hour going into a curve, more data has been revealed in an on-board camera from the front the engine. Sumwalt says it captured the final fateful minutes before the engine and its seven cars went tumbling off the tracks.
"Thirty-one seconds before the end of the recording, the train speed was going through 90 miles an hour. Sixteen seconds before the end of the recording, the train speed was going through 100 miles per hour," said Sumwalt.
Sumwalt wouldn't say who or what was causing the train to accelerate, even though the speed at that area was only 50 miles an hour. The NTSB official also confirmed that the train engineer has agreed to be interviewed by federal investigators and will be asked to provide his own account of what happened the night of the derailment.

As KYW Newsradio reports, an Amtrak employee filed the first lawsuit against the company in connection with the crash on Thursday.
Exclusive video obtained by CBS 3 Eyewitness News shows the actual crash from a surveillance camera.
On Friday, The NTSB held another press conference to give an update on the investigation into the train derailment after they spoke with the engineer and conductors. FBI officials are now looking into whether something struck the train before it derailed.

The NTSB says it's possible some other object may have hit the windshield, but that damage was not caused by a firearm.
Officials say at least 200 people were injured in the wreck -- at least eight of those injuries were critical. Dozens underwent surgery for various injuries and were hospitalized at Temple University Hospital, Albert Einstein Medical Center, Aria Health Frankford Campus, Thomas Jefferson University Hospital and Hahnemann University Hospital.

Passengers Share Their Stories
CBS 3 Eyewitness News spoke with a mother who was on board the train with her son when disaster struck.
"We were just on the train and all of a sudden it started to shake," said Joan Helfman. "And we were in the front seat and this huge red suitcase just came flying at me."
When asked what was going through her mind, Helfman said, "this is a nightmare and it can't be happening."
"I saw so many head injuries and bloody faces," she said. "There was nothing I could do to help, except talk to the people."
"I helped my mom get off. That was my first priority," said her son, Max.
"Luckily I'm still here. I'm still walking," he said. "I got really lucky, so I figured I would do my best to help because I saw everyone. I could see the blood on people's faces."
"I did my best to try to help people out of that car because it was smoking," he explained.
"It kind of still feels like a dream, like how could this happen? You always like read about things or see things on the news like oh, a plane crashes or a train derails, but you never actually think it's going to happen to you, and it did," Max said.
Passenger Jeff Cutler told Eyewitness News' Chris May, "We were going around the curve at some speed and the car went into what seemed like flight for a split second. Then it tipped over and hit with a thud."
He added, ""I'm counting my blessings that I'm in one piece. I feel very sad for those who lost their lives. The randomness of this event crosses my mind. You think you're safe on a train where things like this don't happen."
Former Congressman Patrick Murphy was also on the train, taking to Twitter within moments of the crash:
U.S. Sen. Tom Carper (D-Del.) had been on the train earlier and exited in Wilmington and was not involved in the derailment, according to his office.
"I am grateful to be home safe and sound in Wilmington, and my heart goes out to all those on the train tonight. I hope all of those that are injured recover quickly, and I will keep them in my thoughts and prayers."
