Long-lasting Honks: The extra-large 5-gallon 8-port air tank delivers up to 5 seconds of power, uninterrupted honking.

IMPORTANT: Our Nathan AirChime train horns are sourced from retired locomotives and undergo extensive reconditioning. This process includes sandblasting, a new black powder coat finish, and replacing all internal components such as diffuser rings, diaphragms, and cushion rings. This ensures each horn performs like new and retains its authentic locomotive sound.
