Trenes Argentinos is the name of Argentina's state rail services, which operate commuter lines around Buenos Aires and long distance trains across the country. Recordings of its trains are shared online by travellers and rail fans documenting everyday journeys, station arrivals and departures. Short clips like this later spread to soundboards because the rolling stock, track noise and passing carriages are instantly recognisable to Argentine listeners. It remains popular for adding local realism to travel videos and for joking about commuting, delays and long trips.
