Except that the head of the the NTSB is on record saying deregulation did not have an effect on this accident based on the train by type.

NTSB Chair Jennifer Homendy said…

“The ECP braking rule would've applied ONLY to HIGH HAZARD FLAMMABLE TRAINS. The train that derailed in East Palestine was a MIXED FREIGHT TRAIN containing only 3 placarded Class 3 flammable liquids cars," she tweeted. "This means even if the rule had gone into effect, this train wouldn't have had ECP brakes."

So, please check your politics and show some empathy for those Americans who are suffering.
