ONCF, the Office National des Chemins de Fer, is Morocco's national railway operator, running passenger trains between cities such as Casablanca, Rabat, Marrakech and Tangier. Its short station jingle has become part of everyday travel in Morocco, heard on platforms before departure and arrival information. As clips and recordings were shared on social media and soundboards, the chime moved beyond the station, becoming a recognisable Moroccan travel reference that people reuse for announcements, edits and nostalgic posts about train journeys.
