[flagged]
Here is the USDOT press release from 2017 on this: https://www.phmsa.dot.gov/news/usdot-announces-intent-repeal... Can anyone speak to whether these electronically controlled pneumatic brakes would have prevented or lessened the severity of this derailment in Ohio?
If they didn't brake... then the brake technology had no effect. If they did brake, more sophisticated brake control systems could definitely stop it faster, and would reduce internal stresses that can could contribute to derailment.
My personal speculation is that the crew tried to gamble and get the train to a more convenient stopping location, either of their own volition or as directed by dispatch.
