It says the lead engine derailed, as well as some passenger cars.
There were eight crew members and some 139 passengers on board.
Emergency services have transported around 70 injured people to local hospitals, according to the Lexington Sheriff's office.
However all passengers have been taken off Train 91.
Several injured passengers were seen walking along the tracks after being evacuated, according to reports on social media.
Passenger Derek Pettaway said he was travelling south from Philadelphia to Orlando in a sleeper cabin when he was awoken by the impact of the crash.
He said Amtrak staff evacuated passengers in a "really calm fashion" and added: "It's all very calm here. The Red Cross are here and everybody is being taken care of."
The South Carolina Red Cross has opened a "reception site" at a nearby school.
