Dispatcher means any individual who dispatches.
Emergency means an unexpected and unforeseeable event or situation that affects a railroad's ability to use a dispatcher in the United States to dispatch a railroad operation in the United States and that, absent the railroad's use of an extraterritorial dispatcher to dispatch the railroad operation, would either materially disrupt rail service or pose a substantial safety hazard.
