LOCOMOTIVES Act

HR 3194, the LOCOMOTIVES Act, prevents states from setting their own emissions standards for locomotives used in interstate commerce. It amends the Clean Air Act to clarify that federal emissions rules exclusively apply to locomotives providing common carrier railroad transportation for hire (like commercial freight or passenger services across state lines), excluding these from state regulation. This directly affects railroads operating interstate services and state environmental agencies that previously could establish stricter local rules for such locomotives. The bill does not change the actual emissions requirements but shifts regulatory authority solely to the federal government for this specific category of locomotives.
