A video posted to YouTube appears to show footage of Monday's Blue Line train derailment at O'Hare International Airport.
The video, which was deleted just hours after being posted Tuesday night and was re-posted Wednesday morning, shows a train coming into the Chicago station and crashing into escalators.
Wednesday's video was posted by user SuccessHab on YouTube. While the footage is the same, it is not clear if it was posted by the same user or where the footage came from.
The CTA could not be reached for comment about the video.
Thirty-two people were injured, none seriously, when an eight-car train continued through the end of the platform and struck the escalators leading to the terminals at O'Hare International Airport early Monday morning.
"The train actually climbed over the last stop, jumped up on the sidewalk and then went up the stairs and escalators," Chicago Fire Department Commissioner Jose Santiago said of the crash, which happened just before 3 a.m. on the CTA's Blue Line.
Niakesha Thomas, 22, claims her "job requires her to stand continuously and her injuries have left her currently unable to walk."
"I can't use bathroom by myself, I can't take a bath," Thomas told NBC 5.
Thomas says she was sitting in the third car of the train when the accident occurred.
"I heard a big noise, I felt my chest hit the seat in front of me, and then my back hit the seat behind me and then the lights went out," Thomas said. "I got up, I walked out and I hollered, I got scared, I started shaking, I was a nervous wreck."
A National Transportation Safety Board spokesman said Tuesday an emergency stop system activated as it should have but failed to stop the train.
Twenty-three-year-old Dalila Jefferson, a security officer at O'Hare, also filed a lawsuit Tuesday. She was riding in the first car when the train jumped the tracks and landed on the stairs and escalators leading to the airport terminals.
“It’s clear there was a failure on multiple levels. We hope this lawsuit helps bring answers as to how this could happen and to prevent it from happening again,” Jefferson's attorney Matthew Jenkins said. “Millions of people ride the CTA to and from work and they deserve to feel safe."
CTA union president Robert Kelly told reporters Monday afternoon that the operator of the train may have dozed off.
"The indication is there, yes," Kelly said. "She has worked a lot of hours in the past weekend, and the indication is there."
The operator was interviewed by the NTSB Tuesday for about two hours.
