Train Horn Gun

Power, Safety, and Control Built In

BossHorn’s train horn gun pairs a high-output air compressor with real metal train trumpets and our custom control PCB for reliable performance. You get three selectable volume levels, motor overheat protection, and battery deep-discharge safeguards — all controlled wirelessly up to 2,000 feet. The system accepts genuine tool batteries from major brands and is hand-assembled in the U.S., so every unit sounds loud, manages heat, and protects the battery while staying fully portable.

Designed For Use, Not Installation

The train horn gun comes ready to use—no vehicle mounting or wiring required. Pop in a compatible tool battery, press the remote, and it delivers instant, attention-grabbing sound for roadside emergencies, farm work, or event signaling. The trumpets project a clear, metallic tone while the compressor cycles smartly to avoid overheating; it’s ideal for crews who need fast deployment and for weekenders who want a bold, portable alert.

Reliability You Can Hear

Looking for a train horn gun that works with DeWalt batteries on long jobsite days?

We hand-assemble each unit in the U.S. using real cordless drill components. Our control PCB was designed specifically for drill-powered train horns. You can switch between three volume levels without touching the unit. The system protects the motor and the battery from damage. BossHorn started this category, and we still build them to be used hard.

BossHorn’s focus on genuine tool-brand batteries, custom electronics, and metal trumpets makes the train horn gun a practical, durable choice. The remote range and thermal safeguards reduce hassle and downtime, and the rugged sound ensures you’re heard in noisy environments or across open terrain.
