Around 20 people were hospitalized after an Amtrak train partially derailed while traveling from Los Angeles to Chicago early Monday, officials said.
Five coaches of the Southwest Chief derailed just after midnight local time (1:00 a.m. ET) around 20 miles west of Dodge City, Kansas, the company said in a statement.
Amtrak said it was working with BNSF, which owns and maintains the track, to investigate the cause of the incident.
Of the 128 passengers and 14 crew on board, around 20 people were transported to local hospitals, according to the firm.
One passenger, 25-year-old Los Angeles resident Daniel Szczerba, told NBC News that he “did not feel an impact, [it] simply felt like we were traveling off of the rails.”
