ALWAYS OUTPERFORMING THE IMPOSTERS

Looking for an authentic train horn? How about the same horn that is used on many locomotives to this day? With our Nathan AirChime K3 544K train horn kit, you get the real deal: an actual train horn pulled straight from a retired locomotive powered by one of our premium onboard air systems! These die-cast horns are not for the faint of heart. If you are wanting the same thundering train horn sound you hear when you are stopped at the railroad tracks, this is the kit for you!

Authentic Locomotive Experience: Sourced directly from retired locomotives, the Nathan Airchime K3 ensures the thunderous, genuine train horn sound we are all used to.
Robust Die-Cast Construction: Constructed from die-cast aluminum with stainless steel internals, the Nathan Airchime K3 was built with durability in mind, and designed to withstand various conditions.
Premium Onboard Air System: Paired with a 1NM air compressor and a 5-gallon air tank this system provides roughly 7 seconds of honk time and the ability to use air tools and inflate tires.

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.

Forget regular car alarms - our Train Horn will give those car thieves a stain in their undies! With its ear-splitting volume and unmistakable tone, our train horn will stop any criminal in their tracks. Check out our video below to see for yourself how our Train Horn outperforms any other car alarm on the market. Protect your ride with this ultimate deterrent - the only alarm that’s sure to get your neighbors’ attention!
