Which statement describes the Advisory transmission process?

• A. A ramp on each end of the platform used for boarding and alighting passengers with mobility impairments.
• B. An unforeseen event or occurrence which results in injury or property damage.
• C. A track other than a main track.
• D. Information communicated by radio to all trains which must be acknowledged back to Control by all Train Operators in train number sequence and recorded on their clearance.

Answer: (D)

Advisory transmission is a radio-based safety communication where Control sends information to all trains, and every Train Operator must acknowledge receipt back to Control in train number order, with that acknowledgment recorded on the train’s clearance. This setup creates a verifiable, coordinated flow of information so that every train is aware of the advisory and Control knows which trains have confirmed it, helping to manage operations safely and efficiently. The other descriptions describe things unrelated to advisory transmissions: a ramp on the platform relates to accessibility features, not communications; an unforeseen event causing injury or property damage describes an incident, not a transmission protocol; and a track other than the main track refers to track types like a siding, not to how advisories are transmitted and acknowledged.
