I have watched almost zero coverage of this and I am not a in any way shape or form qualified to talk about trains.NTSB already said this had nothing to do with the accident, and to please STFU.
No wonder so many want to see heads on pikes.
But it seems logical to me that if the trains had better brakes, once a car has derailed (which everyone is saying was because of a bearing), you could slow down the other cars such that less of them pile into the wreckage? No?
So the wreck can be caused by an unrelated issue, but better brakes might still prevent a small accident from becoming a bigger one?
