System Bulletins are official, timely notices from the Operating Rules Department that convey safety-related instructions or requirements affecting how trains operate and how employees perform their duties.

This makes them distinct from a timetable (which lists train schedules), a weather report (which provides conditions), or a locomotive instruction manual (which covers equipment operation).
