The Train-Chan name comes from the soundboard and meme pages where this loud horn clip circulated, rather than from a single official release. Online, it became shorthand for an exaggerated train arrival, with creators pairing the distorted horn with train footage, chase scenes, and the popular Spider-Man train edit that many viewers search for. Its appeal is simple and repeatable: the noise is instantly recognisable, easy to drop into a short video, and works as a punchline on its own. That simplicity has kept it in rotation for reaction edits, compilations, and short-form memes.
