Hornblaster HK-S4-544K All standard mounting hardware
Horn Blasters Conductor’s Special 544 Nightmare Edition train horn kit you get a complete kit that not only has some of the loudest horns you can buy, but also an onboard air system that can handle anything from tire inflation to air suspension. If you need a workhorse out of your onboard air system and still want to be as loud as possible, this is your kit. No Conductor’s Special kit would be complete without our legendary Shocker XL rain horns. Our Shocker XL train horns are hand-tuned to the US Train Horn Chord and are designed to sound like and pack as much of a punch as an authentic locomotive horn! Constructed from an ultra-durable fiberglass-reinforced ABS composite with stainless-steel diaphragms and backed by a lifetime warranty against manufacturer defects, you get a train horn that is not only insanely loud but ridiculously durable as well. The backbone of our Conductor’s Special 544K train horn kit is our 544K onboard air system. Our 5-gallon black 8-port air tank supplies you with enough air to honk the Shocker XL train horns for up to 10-12 seconds as well as handle just about any pneumatic job you can throw at it. Our Nightmare Edition includes a beautiful Stealth Black Viair 444C air compressor that is known for its performance and dependability, able to recover the 5-gallon air tank from 110 to 150 PSI in just 2 minutes and 50 seconds.
