Hear these horns now!

A popular choice for anyone that doesn’t have a lot of room to work with, our Conductor's Special 127H Train Horn Kit is one of the most versatile train horn kits available. Our Shocker XL Train Horn and 127H Air Source Unit make the perfect pair when space is scarce. Not only that, but it is the most cost-effective way to get your hands on one of our popular Conductor's Special kits!

Unlike many of the other train horns available, our Shocker XL Train Horns are uniquely equipped to fit in tight spaces. Most train horns come on a huge metal manifold, which looks really cool but can be difficult to fit if you are limited on install space. Our Shocker XL Train Horns, however, are four separate bells made of a super durable ABS composite. What this means is the horns don’t have to all be installed in the same spot and can be spread out in just about any configuration. Don’t let them fool you though, these horns have the full range and volume of the real train horns. Our Conductor's Special kits are not only the second loudest kit we offer, but they are also hand-tuned to the exact US Train Chord specifications, making them the best bang for your buck!

Just as our Shocker XL Train Horn is the perfect horn for tight installs, our 127H Air Source Unit is the perfect system if you are limited on space. While this system is not enclosed and will need to be installed out of the elements, it does have one of the smallest footprints out of all the onboard air kits that are available. Sporting a 1 ½ gallon tank and a Viair 275C Air Compressor, our Conductor's Special 127H Train Horn Kit provides you with enough air for a 3 second blast time and recharges from 90-120 PSI in only 30 seconds! This is a self-contained kit, meaning installation is easy and the only maintenance needed is draining the tank on a regular basis. If you are looking for a big train horn sound in a small package that doesn’t require a lot of upkeep, this is the kit for you!

(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. **
