The Conductor’s Special 544 Nightmare Edition train horn kit was designed from the ground up to deliver the maximum level of shock to anyone unlucky enough to be anywhere nearby! Paired with a set of twin 444C Compressors, this Nasty 220 Watt air system will have no problem keeping the 5 gallon air tank filled and ready at all times!

Listen to these horns:

The Conductor’s Special 544 Nightmare Edition train horn kit delivers the performance you need in the style you crave. The Shocker 544 features the insanely loud, American-made, Shocker Horns. These horns are ridiculous and, more importantly, actually sound like a train! They are hand-tuned in the USA to the government mandated train signal chord. Simply put, they sound completely authentic.

Coupled with these impressive horns is an even more impressive air system. This air system was designed from the ground up to work amazingly with train horns and it does just that. The 5-gallon tank can recharge from 110 to 150 PSI in just 2 minute and 20 seconds! This is because we matched an overpowered 444C compressor. This compressor is complete overkill: rated to 200 PSI for reliability, constant duty, and powerful. The air system features everything you’ll need to have an extremely loud train horn kit up and running in no time; including, a weatherproof pressure switch with built-in relay, all the fittings, and airline you’ll need, and of course the wire and terminals to get it all hooked up.


If you’ve ever planned on adding air suspension, now you’re halfway there. What about air tools? With 5 gallons of air, you’ve got more than enough to run air tools, air jacks, air ride, or even inflate tires.

Also featured in this kit is a remote mountable intake assembly, or “Snorkel Kit”, for the air compressor. This allows the compressor to be mounted just about anywhere where it would normally suck up dirt, debris, moisture, or any other contaminant. You can place the air intake filter safely up to 6 feet away with the included airline!
