What is a Passenger Information Display (PID) and its purpose?

• A. A display that shows station announcements only.
• B. A device used to broadcast internal staff announcements only.
• C. A system that records maintenance activities.
• D. A display that shows train times, arrivals, and platform information to help passengers.

Answer: (D)

A Passenger Information Display is a screen that shows train times, arrivals, and platform information to help passengers. Its purpose is to provide up-to-date, easy-to-read information about which train is coming, where to go, and any delays or platform changes, so travelers can plan their movements and navigate the station smoothly. These displays pull data from timetable systems and live service feeds, keeping information accurate and helping reduce confusion. The other options describe announcements for staff, or records of maintenance, which aren’t meant for passenger-facing visibility.
