Nathan AirChime K3LA (K3 Low Mount American Tuning) Authentic Railroad-Use Train Horn

The Nathan AirChime K3 has long been the leader in commercial railway horns. This horn is the most commonly used horn on diesel locomotives across the US and is the same horn everyone's familiar with when a diesel locomotive barrells down its tracks.

This K3LA is an American tuned version of the K3 with a low-profile mount to make it easier to install on trucks (not intentionally). The K3LA is an amazing horn and delivers unbelievable power. Honestly its very hard to describe just how loud these horns are. If you want a real horn, this is the answer.

K-Series Power: K-Series Train Horns Deliver The Most Out Of Any Train Horn! Ever!

Developed in the 1950s this K-series horn is a blast from the past. In fact although there are many variations of the K3, the basic design has stayed the same since 1954. This horn is just about indestructable; die cast out of solid aluminum and powered by heavy duty stainless steel internals. This horn can take a beating!

Still not confident about these horns? They were designed to be mounted on diesel locomotives and be exposed to the elements, snow, ice, rain, wind, and diesel smoke and still sound great! In fact these horns were designed to be clearly audible from up to 5 miles (calm wind, clear skies). The horns are virtually maintainance free and are designed to be rebuilt with absolutely no tuning necessary.

Revolutionary Train Horn Design

The K-series horns boast an impressive design. These kettle-drum horns were designed to sound louder than their predecessors. Although, they are not quite as deep as older horns, these horns are 11 dB louder at 100ft than the P-3 was and play a much more alerting tone. To put it simply, these horns are designed to catch peoples attention.

This horn features an innovative technology unheard of in other horns. The diaphragm housing of the horn actually contains two discs. This may be Greek to some, but what it means is the horns don't taper in tone like normal horns. Regular horns sound a lot more high pitched at high pressure than they do at lower pressures. With a K-series horn you're all full-on or full-off.

The Most Authentic Train Horn For Your Car Or Truck

If you want a real train horn, this is the most authentic one you can buy. Since its the most popular horn used on locomotives to this day you will sound exactly like a train. In fact, with one of our kits you'll be louder than a train. The reason is because our horns run at a higher pressure than locomotives run theres (150-200 PSI vs. 130 PSI). Quite simply, if you want to sound like a train, and we mean sound identical to a train, this is the horn you need to buy.
