What does this do?
This bill would block all states from setting their own emission rules for locomotives used in commercial railroad transportation. Right now, federal law already limits some of that state authority, and this bill would expand that limit to cover all locomotives.
Who does it affect?
Railroad companies running freight and passenger trains across the country would be directly affected. States like California that have tried or may want to create stricter train emission standards would lose the ability to do so.
Why does it matter?
Only the federal government, through the Environmental Protection Agency, could regulate how much pollution trains are allowed to emit. No state could set its own standards, even stricter ones.
