Travys is the public transport operator serving Yverdon-les-Bains and the surrounding Nord Vaudois region of French-speaking Switzerland, running regional trains and local buses. Its older station and vehicle announcements, delivered in French in a formal public-address style, have a distinctive sound that transport enthusiasts and local listeners recognise immediately. Short recordings of these announcements now circulate as soundboard clips, kept alive less as jokes than as small pieces of local transport heritage, and they are reused to set a scene, signal a departure or add an authentic Swiss touch to travel edits.
