Subway Bridge

The audio begins with the distant hum of a bustling city, the signature sounds of the suburban life in the background. Gradually, the noise grows louder, transforming into a rhythmic rattling sound that dominates the audio scape. The rattling is consistent, repetitive, a clear indication of a metro train zipping across the tracks. The sound of the train is accompanied by a low, continuous rumble, suggestive of its journey over an overpass, adding a sense of depth and dimension to the audio. The train's mechanical rhythm is interspersed with occasional high-pitched squeals, likely from the friction between the wheels and the tracks. Every so often, the train's rumbling is overlaid with the faint chimes of a tram passing by, its bell clinking a merry tune that contrasts with the steady drone of the train. The audio paints a vivid picture of public transport in motion, each element - the train, the tram - contributing to the bustling soundscape of the city.
