These horns have never been so loud. The Conductor’s Special 244 Nightmare Edition train horn offers the power of the Viair 444C and incredible performance of the Shocker XL horns to bring you the loudest compact horn kit on the market. This edition also features a stealth black finish on the 444C.

Simply put, this is the best 150 PSI compact train horn kit currently available. It’s designed specifically for smaller vehicles where larger tanks may not fit. The compressor is overpowered (200 PSI capable, constant duty, and powerful!) to ensure the best reliability, and only pulls 19 amps at its peak. At 150 PSI, the Shocker horns are simply ridiculous!
