Title 49 › Subtitle SUBTITLE V— - RAIL PROGRAMS › Part PART A— - SAFETY › Chapter CHAPTER 211— - HOURS OF SERVICE › § 21102
Some situations are not covered by the duty-hour rules. That includes a casualty, an unavoidable accident, a natural disaster, or a delay that the railroad and the supervisor in charge could not know about when the worker left the terminal. The Secretary of Transportation can exempt a small railroad that has 15 or fewer employees covered by these rules. The Secretary must hold a full hearing, find good cause, and decide the exemption is in the public interest and won’t hurt safety. Any exemption is for a set time, reviewed at least once a year, and cannot let employees work more than 16 hours in any 24-hour period. For commuter and intercity passenger trains, the old duty-hour rules apply until the Secretary issues new regulations or until three years after the Rail Safety Improvement Act of 2008. After that, the updated rule applies. When the Secretary’s regulations take effect, carriers must follow those regulations and are no longer bound by the old or updated versions of the prior rule. "Old" and "new" refer to the rule before and after the 2008 change; "commuter" and "intercity" are defined elsewhere in the law.
