Hear these horns now!

Struggling to be heard with your current horn? Make those distracted drivers think they just cut off a locomotive with our Nathan AirChime P3 540 Train Horn Kit! Outfit your ride with the full power and classic tone of an authentic train horn straight out of the ’50s. Coupled with our HornAir 540 Onboard Air System, the Nathan AirChime P3 540 Train Horn Kit is a powerhouse train horn kit sure to startle those that defy you.

Horns made to be heard for miles and last for decades, the sand-cast Nathan AirChime P3 Train Horn included is for anyone serious about train horns. Unlike some of our other train horns, the Nathan AirChime P3 Train Horns are created using sand-casting instead of die-casting. This allows for the internal chamber to have more of an oval shape creating a tone that is impossible to duplicate, making Nathan AirChime P3 Train Horn the perfect horn for anyone wanting to stand out.

Such a massive horn requires an onboard air system that can keep up. Our HornAir 540 Onboard Air System brings more than enough power to the table, not only powering your Nathan Airchime P3 Train Horn but also providing onboard air for emergency situations. Our Black 5-Gallon 8-Port Tank supplies enough air to blast your Nathan Airchime P3 Train Horns for up to 5 continuous seconds and the lightning-fast Viair 400C compressor powering the system can recharge our 5-gallon tank in only 1 minute and 40 seconds, making the Nathan AirChime P3 540 Train Horn Kit one of our fastest filling kits to date!
