What are visual announcements?

• A. Spoken updates over the public address system.
• B. Audible beeps signaling train departure.
• C. Warnings shown only as text on the platform.
• D. Indications displayed on signs or displays showing train times, routes, and alerts for passengers.

Answer: (D)

Visual announcements are information shown in a readable form on signs or displays at stations. They present train times, routes, platform changes, and service alerts for passengers to read as they wait. This makes them accessible in noisy environments and for those who cannot hear audio updates. That’s why indications displayed on signs or displays showing train times, routes, and alerts is the best description. Audio updates or beeps aren’t visual, and while text on a platform is visual, it’s the ongoing display of times and routes that characterizes visual announcements.
