              FILE - Workers stand, Sept. 27, 2021, near overturned cars from an Amtrak train that derailed a few days prior near Joplin, Mont., killing three people and injuring others. A piece of track was bent along a curve near the accident site and the misalignment got worse as freight trains traveled over the area prior to the derailment, the National Transportation Safety Board said in investigative documents released on Tuesday, Feb. 21, 2023.
