SNCF introduced this four-note sonic identity in 2005 as part of the French railway company's updated branding. It was created by composer and sound designer Michaël Boumendil, founder of the audio branding agency Sixième Son. The melody became familiar through repeated use before announcements across the French rail network. British musician David Gilmour later adapted the notes for “Rattle That Lock” after hearing the jingle at a station and obtaining permission, giving the compact railway melody recognition beyond France.
