(FIRST REPORT) An Amtrak passenger train derailed in Liberty County on Saturday. The first reports of the derailment came in just after 4:00 p.m.
The train was reportedly just west of Joplin when it went off the tracks.
Pictures shared on social media showed at least one car completely on its side and several other cars upright or tipped but off the tracks.
A witness described helping passengers exit the derailed cars. Jeremiah Johnson told MTN that ladders were being used to free people and some had to be cut free.
"We had to lift a few people out with lots of volunteers and then cut some out...There was one lady in the back whose legs were trapped and was unable to be removed without using a saw (to cut away seats.)," Johnson said.
Johnson described seeing shoulder, head, and neck injuries.
There are reports that passengers are being bused to Chester High School or the Chester Senior Center for staging. Officials have not confirmed to MTN any fatalities as of 6:45 p.m. Saturday evening.
He added that his wife assisted with helping passengers as they got off the train.
"Right now, she's helping out on site and then was kind of checking people's vitals as they were coming. I brought her to the hospital. They had plenty of help up there so we went to the high school and she started helping get down people's injuries, names, and documenting any medication they may be taking."
Johnson estimated there were dozens of people at the high school.
MTN has a reporter at the scene and will update you when more details are available.
