Want one of our famous Conductor's Special train horn kits, but don’t have the room or the budget for one of the bigger kits? Our Conductor's Special 228H train horn kit is the solution for you! Featuring one of our most popular horns, our Shocker XL train horns, this kit is a great 2-gallon 150 PSI entry-level kit. The Conductor's Special 228H is great for tight install spaces, with the air source unit taking up just over a cubic foot of space.

The MVP of our Conductor's Special 228H train horn kit is definitely our Shocker XL train horn. Made of a ridiculously strong fiberglass ABS, the Shocker XL Train Horn is very light. Unlike other horns, they don’t require a big metal manifold, making them the easiest horns to install when space is limited. Just because they’re not huge and metal doesn’t mean they don't have a huge sound, though. Our Shocker XL train horns are the loudest horns on the market, except the real locomotive horns which are the Nathan Airchime train horns.

We paired our Shocker XL train horns with our HornAir 228H air source unit. With its compact size, this system is great for installing in places such as toolboxes or inside a trunk. Our 2-gallon tank gives you about 4 seconds of blast time and the Viair 280C air compressor recovers the tank in only 75 seconds!

(Note: Tank mounted air compressors are not fully sealed. For this reason, the manufacturer recommends the tank/compressor system be mounted in the upright position in an enclosed space away from moisture, dirt, debris, etc... Failure to mount this product as directed will void the warranty)

**Detaching the compressor from the tank will void your warranty on this kit. If you need a solution where the compressor is detached, please look at our 232 and higher models. **

Please note: The 6 horn upgrade kit does NOT include the extension brackets to connect to our Shocker XL horn mount.

This video shows our Shocker XL train horn in a third-party decibel test alongside your typical "air horn" honked side-by-side at the same pressure. As you can see, no one even comes close to the insane volume and tone of our Shocker XL train horns!

Bang for your Buck

When I opened the box I was skeptical about the horns. The were plastic looking and I was worried about the sound. I was wrong. These horns are loud as ****! I’m talking my wife running out for restroom cause it literally scared the **** out of her! Do yourself a favor and buy these horns. And but the remote and press that little red button!

Blown away with these horns

These horns are easy to install and sound great. Made my own bracket out if 1/8 inch diamond plate and mounted it where the spare tire would go. Strongly recommend these horns. Customer service is very helpful as well if you need them.
