The clip comes from the Trainz train simulator community, where the Renfe AV01 high-speed unit was recreated for Trainz 2012 and Trainz Mobile. Renfe is Spain's national passenger railway operator, known for its AVE high-speed services. Players shared the model's distinctive Ave Maria horn as a standalone file, and it spread among railway simulator fans who collect authentic and unusual train horns. It remains a niche favourite for Spanish train content rather than a mainstream meme sound.
