RTW is the standard German abbreviation for Rettungswagen, the emergency ambulance operated in Hamburg by the Feuerwehr Hamburg, the city's fire and rescue service. Recordings like this are shared by emergency vehicle fans and simulator players who document different siren tones and pass-bys. The German two-tone horn differs clearly from American wail and yelp sirens, which is why creators specifically look for it for European scenes. Online it is used mainly in roleplay communities, vehicle spotting edits, and realistic city sound design.
