This audio captures a distinct and jarring screeching noise echoing through a metro station. The source of this cacophonous sound is an old escalator, laboring to carry passengers up and down. The grinding, screeching noise it produces reverberates throughout the station, creating an eerie, almost unsettling backdrop to the usual hustle and bustle of commuting life. The shrieking metallic cries of the escalator, struggling to function, form a dissonant symphony which is almost synonymous with the urban, metropolitan experience.
