K5LA.com. When "Loud" Just Isn't Loud Enough

K5LA.com is dedicated to bringing you the loudest, authentic train horns available. Our horns are used on diesel locomotives all over the USA and are manufactured by The name in locomotive air horns, Nathan AirChime.

The K series train horns are considered the "industry standard" for railroads across the nation. This means these horns are the real deal. They are sold to locomotive manufacturers and fleet operators, as well as the general public. Ever dream of being a conductor and sounding the horn as you fly through a crossing? These horns are as close as you can get.

If you're looking to be the loudest, then look no further. You've heard a train barreling down its tracks from miles away before; now imagine that same powerful horn (identical horn!) installed in your very own car or truck. That's where we come in.

We provide a complete real locomotive horn setup with HornAir brand 12 volt air supply. In fact, with this kit your horn will be even louder than a train! This is because locomotives run their horn systems at 130 PSI, whereas this kit will power your horns with 150-200 PSI. That's a huge difference!

K5, K5H, K5LA, The Loudest Train Horn Ever Made

Whatever you want to call it, the K5 is the loudest train horn ever to hit mass production! This popular horn has many variations from different pitches to different mounting positions. What's important is that it's a K5.

The K series horns were designed to sound louder than their predecessors. The kettle-drum bells sound 11dB louder at 100 feet than the previous Nathan Airchime P-3 model, and even play a more alerting tone. These horns will blow you away!

These horns provide a ridiculous amount of power. In fact, they sound with almost too much power; sustained exposure will cause hearing loss! These horns should not be used in a closed environment and hearing protection must be worn when sounded.

Why Would You Need A Train Horn?

Never be ignored on the road again! Whether it' a child running out into the road, or an unknowing deer in the middle of the street, your train horn will amplify your concern to unbelievable levels. Sometimes stock horns are overlooked, or the punier ones may not even be heard at all! With a train horn, you're guaranteed to be heeded in all situations, and it's also an easy way to make others aware in an emergency situation. So next time that obnoxious driver cuts you off on the highway, make sure he knows you were there first!
