220.2—Preemptive effect.
Under 49 U.S.C. 20106 (formerly section 205 of the Federal Railroad Safety Act of 1970, 45 U.S.C. 434 ), issuance of the regulations in this part preempts any State law, rule, regulation, order, or standard covering the same subject matter, except a provision necessary to eliminate or reduce an essentially local safety hazard that is not incompatible with this part and that does not unreasonably burden interstate commerce.
