Summary

Makes railroad safety and security rules the same across the country whenever possible. States can keep or make their own railroad safety or security rules until the federal government issues a rule or order on the same topic. A State may have stricter or extra rules only if they are needed to fix a local safety or security danger, do not conflict with federal rules, and do not unreasonably hurt trade between states. People can still sue under state law for injury, death, or property damage if they claim someone broke a federal safety or security rule (by the Secretary of Transportation for safety or the Secretary of Homeland Security for security), broke its own plan made under a federal rule, or broke a compatible state rule. That applies to cases from events on or after January 18, 2002. This does not create a new federal right to sue or give federal courts automatic authority over these state cases.

(C)does not unreasonably burden interstate commerce.

(A)has failed to comply with the Federal standard of care established by a regulation or order issued by the Secretary of Transportation (with respect to railroad safety matters), or the Secretary of Homeland Security (with respect to railroad security matters), covering the subject matter as provided in subsection (a) of this section;
(B)has failed to comply with its own plan, rule, or standard that it created pursuant to a regulation or order issued by either of the Secretaries; or
(C)has failed to comply with a State law, regulation, or order that is not incompatible with subsection (a)(2).
(2)This subsection shall apply to all pending State law causes of action arising from events or activities occurring on or after January 18, 2002.
