The recording comes from the automated announcement system used on Istanbul Metro's M2 line, which runs between Yenikapı and Hacıosman with a branch to Seyrantepe via Sanayi Mahallesi. Similar announcements are collected under Istanbul transport archives credited to İETT and metro announcements. The message simply warns passengers how long the incoming train will be, helping them position themselves on the platform. Shared online by Turkish commuters and transit fans, it has become a recognisable clip for videos set in Istanbul stations.
