This bill would change the Clean Air Act so that states cannot set their own pollution rules for existing locomotives and their engines. Instead, only federal rules would apply. It says this covers trains “engaged in commerce,” which includes locomotives that provide common carrier rail service for pay, like freight and passenger trains that run as part of the national rail system .

In short, states would lose the power to require cleaner engines or set special emissions limits for older trains. Rail companies would follow one national standard, not different rules in different states .

Who is affected: Railroads that run freight and passenger service; state air agencies; communities near rail yards and tracks .
What changes: States would be barred from creating or enforcing emissions standards for existing locomotives and their engines; federal standards would control .
When: The text amends the law but does not state a specific start date in the provided section .
