Ironworkers cut up the derailed Blue Line train once the NTSB released the crash site to the CTA. The NTSB completed its on-site investigation on Wednesday and returned to its headquarters to review the information. That's when CTA crews started clearing up the wreckage.
No one was seriously injured early Monday when the Blue Line train derailed at the O'Hare stop. The driver told NTSB investigators she fell asleep, and an automatic emergency braking system did not stop the train.
CTA employees who usually work on the elevated tracks said cutting apart the large pieces of metal isn't easy. However, most of the damage was limited to just the one car that jumped the tracks and struck the elevator.
The rest of the car was pulled intact out of the station.
Officials are now looking the structural damage at the station. CTA hopes to have the station reopened by the weekend, but will continue to run buses between the Blue Line's O'Hare and Rosemont train stations.
The derailment is estimated to have caused $6 million in damages to just the tracks and equipment.
