What do boarding advisories typically include?

Boarding advisories commonly include security alerts and safety announcements to ensure the safety and security of all passengers before they board the train. These advisories are crucial in preparing passengers for any potential safety protocols that they need to adhere to, like evacuation procedures or reminders of prohibited items. The emphasis on security and safety is paramount in the transport industry, particularly in the context of public transportation, where large numbers of people gather.

In contrast, while weather updates and train delays play an important role in passenger awareness, they aren't typically included in what is classified as a boarding advisory. Passenger seating arrangements and meal selections also do not fit into the core purpose of boarding advisories, which is focused on safety and security information rather than logistical or hospitality details.
