Russian Railways, known as RZD, operates the national rail network in Russia, and its stations use short musical chimes to draw attention before spoken announcements about trains. Clips of these chimes have circulated online as train sound effects, where they are recognised by travellers and rail enthusiasts even without any words. Because the sound is brief, clear, and tied to a specific place, it remains popular for travel vlogs, train simulator videos, and edits about journeys through Russia, where it instantly sets a station scene.
