Title 49 › SUBTITLE V — RAIL PROGRAMS › PART A — SAFETY › CHAPTER 201 — GENERAL › SUBCHAPTER II — PARTICULAR ASPECTS OF SAFETY › § 20171
Sets rules for which freight rail cars can run on U.S. rail lines. Cars made on or after the date that is 1 year after the government issues new rules must be made, put together, and mostly changed (when needed) by a manufacturer and factory that are not controlled by a government-owned company. Any onboard “sensitive technology” (things with electronics or connectivity) cannot come from a listed country of concern or from a state-owned company. Other parts of the car (not counting sensitive technology) may not come from those sources more than 20% by net cost at first, and not more than 15% by net cost starting 3 years after the rules are issued. The Transportation Secretary must write the rules within 2 years after the Passenger Rail Expansion and Rail Safety Act of 2021 became law. Manufacturers must certify every year that their cars meet these rules, have a valid certification when a car starts service, and may not register noncompliant cars in the industry system. The Secretary can fine $100,000 to $250,000 per car for each violation and can stop a manufacturer with more than 3 violations from supplying cars until they fix problems and pay all fines.
