Hear these horns now!

A train horn kit that can do it all and look good doing it, our Conductor’s Special 244K Nightmare Edition Train Horn Kit has been the go-to train horn kit for years. With enough volume to wake the dead and enough power to handle most pneumatic jobs you can throw at it, our Conductor’s Special 244K is one of our most well-rounded kits and a solid addition to any vehicle. 

Our Conductor’s Special 244K Nightmare Edition Train Horn Kit features our legendary Shocker XL Train Horns. Hand-tuned to the exact specifications of the US Train Horn Chord and packing just as much power as an authentic train horn, our Shocker XL Train Horns are the closest you can get to the real deal without having to spend thousands on a retired locomotive train horn. Constructed from an ultra-durable fiberglass-reinforced ABS composite with stainless-steel diaphragm 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. 

Of course, for horns of this caliber, you need an onboard air system that will keep up. Our Conductor’s Special 244K Nightmare Edition Train Horn Kit is one of our most well-rounded kits, with enough air to blast our Shocker XL Train Horns for up to 6 seconds, as well as handle most pneumatic applications such as air tools or tire inflation. Our Nightmare edition is powered by Viair’s 444C Stealth Black Air Compressor, recharging our 2-Gallon 6-Port tank in roughly a minute. With hardware and instructions included, you get everything you need to get back out on the road and honking. 

An increasing number of people are using this for more than just blasting horns! With a system like the Conductor’s Special 244K Train Horn Kit, you can also use the air supply to:

  • Adjust Tire Pressure
  • Light Pneumatic Use
  • Inflate Water Toys and Safety Gear
  • Supply Air to Load Leveling Bags
  • Supply Air for Differential Lockers
  • Blow up Kids Toys
  • And lots more!

This kit is great!

This kit does really good with the spare tire delete kit. The horns are really loud and everything feels like good quality. The only thing I wish they did was send an additional 1/4” NPC to PTC fittings for the air gauge. So it could be mounted to an easy viewing point. The instructions where kind of confusing for the dual air tanks but i figured it out just some minor details I would have liked to have a dual air tank installation wiring diagram but I’m also not good at wiring lol. But it’s a great kit! I’m very pleased with it.
