This clip is shared online as a sound taken from Garry's Mod, the popular sandbox game where players build scenes, stage machinima and reuse in-game audio for their own videos. Distant train horns like this one are common in that community because they add scale and place without needing a visible train, and the same file has been passed around soundboards for use in memes and edits. It remains useful today because a faraway horn is instantly recognisable, easy to place under dialogue or music, and works for comedy, drama and travel clips alike.
