Nathan AirChime K3LA, Train Horn

The Nathan AirChime K3LA 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 comes barreling down the 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, it's very hard to describe just how loud these horns are. If you want a real train horn, this is the answer.

The standard finish on this horn is unpolished die-cast aluminum. The horns are easily painted, or powder coated but they are not supplied this way.

***This horn does *not* come with a valve. You must either purchase or supply a valve in order to operate this horn with your air system.***
