}Emergency Lighthouse Fog Broadcast
[serious] Atención a todas las embarcaciones en la ensenada de San Telmo. [pause] La niebla se ha cerrado por completo en el canal norte y la visibilidad ha caído por debajo de cincuenta metros. [urgent] Reduzcan la velocidad de inmediato, activen sus señales acústicas y mantengan rumbo de espera fuera de la zona de arrecifes. [pause] El faro principal opera con energía de respaldo; su destello continuará, pero el equipo de puerto informa corrientes cruzadas más fuertes de lo habitual cerca del espigón este. [calm] Si escuchan esta transmisión, confirmen por radio en el canal dieciséis con el nombre de su nave y el número de personas a bordo. [pause] Repetimos: niebla densa, corrientes intensas y acceso restringido al canal norte hasta nuevo aviso.

}Subterranean Transit Wake Announcement
[calm, intimate] Good morning, passengers of the Meridian Deep Line. [pause] If you are hearing this, your carriage has crossed the basalt threshold and entered the oldest tunnel beneath the city. [slightly warmer] On your left, beyond three meters of reinforced stone, an underground river is moving in total darkness toward the western turbines. [pause] Please remain seated while pressure locks cycle. [soft smile] The gentle flicker in the cabin lights is expected; the generators here were installed one hundred and twelve years ago and still prefer their own rhythm. [more focused] In approximately four minutes, we will arrive at Cinder Quay, where transfer doors open to the freight lifts, the night kitchens, and the lower foundry promenade. [pause] Passengers continuing to Ash Garden should stay aboard. [lower, storytelling tone] Local tradition says the tunnel workers once judged the weather above by listening to how the rails sang below. [brief pause] Today, they would have heard a clear, bright note. [reassuring] Thank you for traveling beneath the city with us.

}Romanian Funicular Weather Bulletin
[calm] Bună seara, stimați pasageri. [clear] Funicularul către platoul înalt va pleca în șapte minute de la peronul doi. [measured] Vântul de creastă s-a intensificat, iar temperatura a scăzut sub zero. [reassuring] Personalul a verificat cabinele, sistemele de frânare și traseul de urcare. [slight pause] Vă rugăm să păstrați biletele la îndemână și să fixați bine bagajele mici. [gentle] Copiii trebuie să rămână însoțiți pe toată durata călătoriei.
