The Sydney Light Rail is the tram network serving central Sydney and surrounding suburbs, and its door chime is part of the everyday onboard announcement system that warns passengers before departure. The sound has been shared online by commuters and visitors who recognise it from rides through the city centre, Circular Quay and the inner west. Because it is short, clean and instantly place-specific, creators reuse it as an audio shorthand for Sydney, public transport and urban travel, even when the video itself was not filmed on a tram.
