"Design Flaw Identified as Cause of Chicago Train Crash: NTSB Investigation"
Originally Published 2 years ago — by WGN TV Chicago
The National Transportation Safety Board (NTSB) has revealed that a design flaw in the Chicago Transit Authority's (CTA) braking algorithm was likely to blame for a train crash that left 38 people injured. The crash involved a CTA train colliding with a snow fighter on the tracks. The NTSB's preliminary investigation found that the train failed to properly account for the distance needed to come to a stop due to the design flaw. Additionally, there was a foreign substance on the tracks, and it is unclear if it played a role in the crash. Two lawsuits have been filed by passengers onboard the trains, and CTA Yellow line service has been suspended as authorities continue to investigate.
