> So why “minimal,” then? Get a load of this Kessler logic: “But Cynthia Quarterman, who helped write the rule as administrator of the Pipeline and Hazardous Materials Safety Administration during the Obama administration, told The Fact Checker that if the rule had not been delayed and then shelved, she believes ECP brakes might have been widely adopted by industry and could have ended up on this train.” That's a valid point. Industries tend to take the path of least resistance, that's why everything used to be labeled as "Inspected by the Pennsylvania Department of Agriculture" - it was simply easier to do that for everything than to pick and choose what you're going to have for sale in a given place. It's possible that more (later, all) trains would have had this type of braking system had this passed. But it wouldn't have applied regardless, so the point is moot.
