Gordon has been one of the main engines in Thomas and Friends since the television series began in the 1980s, based on The Railway Series books. As the proud express engine, his whistle became closely linked with express trains, station scenes and moments when he arrives in a hurry. Fans later lifted short audio clips from episodes into soundboards and edits, where the whistle works even for people who did not grow up with the show. Its clear steam sound and short length have kept it useful for train content, nostalgia edits and playful announcements.
