The GTL8 is the eight-axle articulated tram family long associated with Amsterdam, where drivers use a short horn blast, known in Dutch as a toeter, to warn pedestrians and cyclists at crossings and busy stops. Recordings like this circulate among transit fans and editors because the tone is specific to the vehicle rather than a generic horn. Online it appears in tramspotting clips, city sound collections and edits that need an unmistakably Dutch public transport cue without showing the tram itself.
