Air-Powered Train Horns

Engineered Performance & Control

BossHorn train air horn systems pair industrial-grade metal trumpets with a high-output compressor and our custom control PCB. You get three selectable volume levels, motor overheat protection, and battery deep-discharge safeguards. The wireless remote reaches up to 2,000 feet, and units accept batteries from 15+ major tool brands—so the loud, authentic train-air-horn sound is portable, repeatable, and built to run without vehicle wiring or complex mounting.

Ready-to-Use Portability

The train air horn arrives hand-assembled and ready out of the box—no drilling, mounting, or hardwiring. Attach a compatible cordless tool battery or buy a complete kit with one included. Perfect for trail riders who need instant signaling, property owners clearing livestock, or event coordinators who want instant, attention-grabbing sound without permanent installation.
