119th (2025–2027)
H.R. 3194
The LOCOMOTIVES Act would amend the Clean Air Act to prevent states from setting their own emissions standards for existing locomotives and railroad engines. Currently, states can establish stricter pollution controls than federal standards in certain cases, but this bill would block that authority specifically for locomotives used in interstate commerce. The legislation applies to all locomotives engaged in railroad transportation for compensation across state lines, effectively limiting environmental regulation to federal standards only. The bill was introduced in May 2025 and referred to the House Committee on Energy and Commerce. No specific funding or implementation timeline is included in the legislation.
