Under carrier operating rules based on GCOR or NORAC, a train crew that sees a 'flag stop' station shown in the timetable must:

1. Stop at every flag stop station regardless of whether passengers or freight are present
2. Stop only if a flag or light signal indicates passengers wish to board, or if the train has passengers to discharge
3. Pass flag stops at restricted speed to enable visual inspection
4. Contact the dispatcher for authority before making any flag stop
