Don’t settle for a kit that can only handle horns. Our Conductor’s Special 544 train horn kit delivers the loudest train horns that we make and gives you a powerful onboard air system that can do so much more than just power horns. On top of giving you the ear-splitting train horn blast that our Conductor’s Special Kits are known for, our Conductor’s Special 544 also gives you the ability to tackle pneumatic tasks such as airing up tires, running power tools, and supporting air suspension!
If you were looking for the loudest train horns we make, you found them! Our Shocker XL train horn that is featured in our Conductor’s Special 544 gives you all the volume that you could ever need and are hand-tuned to the official US Train Horn Chord, giving you the power and tone of a real locomotive. Constructed of an ultra-durable fiberglass-reinforced ABS composite, our Shocker XL train horns are virtually indestructible and one of the few horns out there that is backed by a limited lifetime warranty.
With such a powerful horn, it only makes sense to back it up with one of our most powerful and most popular onboard air systems! Our Conductor’s Special 544 features the trusted Viair 444C air compressor, known for its durability and performance. This powerful constant duty compressor has a 100% duty cycle, giving you a workhorse onboard air system that can handle any tough job you can throw at it. Our 544 onboard air system will supply enough air to give your Shocker XL train horn a stunning 10-12 second honk time and will recover the 5-gallon tank from 110 to 150 PSI in just 2 minutes and 50 seconds. As with all HornBlasters kits, our Conductor’s Special 544 Train Horn Kit comes complete with all required components and detailed instructions.
