b. Superiority is conferred by the timetable, based on a train's
superior class or superior direction.
A regular train may have timetable
authorization or timetable superiority but not necessarily superiority by
right. If such a train is issued a train order that helps it but restricts
another superior train, then the first train has superiority by right in
addition to timetable superiority.
