Frequently Asked Questions

Do I need onboard air for a true train horn?: Yes. Multi-trumpet “train horn” setups require a compressor and tank. Choose a kit with onboard air (e.g., HP10314 or HP10237) or pair a horn-only kit with HP10163 or HP10164-AL.
How big of a tank should I run?: For occasional blasts, 0.5 gal works. For repeated use or longer blasts, step up to 2.5 gal or add separate tanks like HP10053 (0.5 gal).
What’s the loudest option?: Triple-horn kits deliver the biggest presence. See HP10314 or Kleinn HK6 (requires onboard air).
Is this legal on public roads?: Regulations vary by location and noise ordinances. Use responsibly and check local laws before using train horns on public roads.
