While the Obama administration
had estimatedthat the rule could save more than $1 billion by averting accidents, the Trump administration
rolled out new figures that cut the estimated benefits by a third.
The AAR lobbying group
concurred that “the costs of the ECP rule substantially outweigh its benefits,” and
claimed the mandate would cost them about $3 billion — or roughly
2 weeks of their operating revenue in a typical year. The FRA estimated the brake requirement
would costabout half a billion.
Trump’s Transportation Department ultimately
rescinded the brake rule in late 2017.
