Hear these horns now!


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 entry-level choice. Much like our Conductor's Special 127H train horn kit, our Conductor's Special 228H Train Horn Kit is great for tight install spaces, with the air source unit taking up just over a cubic foot of space. With this kit, however, you get even more air and a higher pressure!

 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 recharges 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...)

**This kit does not fit the Spare Tire Delete Bracket!**

**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 model kits. **

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!

Best Horns you can buy!

I bought a set of “Train Horns” off amazon before I got these. Ones on amazon sounded cheap(like a 18 wheeler horn, not like a train) These are easily 4 times louder than the other ones! Plus these actually sound like a train horn. I installed them in my 2001 Subaru Outback and when you hit the horn it’ll shake the whole car. Now every time I see a train I honk and them and they honk back. Best money I’ve ever spent! Extremely happy! Thanks Hornblasters!
