Cordless Train Horn

Built Around Real Tools and Tough Components

Our cordless train horn pairs a high-output air compressor with genuine drill/impact-driver batteries, metal trumpets, and a custom control PCB. The board gives three volume levels, motor overheat protection, and deep-discharge safety so the motor and battery survive. Remote triggering works up to 2,000 feet, and the unit is hand-assembled in the U.S. The cordless train horn is ready out of the box—no wiring or truck mounting needed.

Simple, Fast, and Truly Portable

The cordless train horn fits the same batteries you already use—DeWalt, Milwaukee, Ryobi and more—and snaps on in seconds. You’ll get instant, attention-grabbing sound without permanent installs, perfect for work sites, farm drives, or weekend trail runs. It’s heavy when it counts (metal trumpets), but compact for carrying. Swap batteries between tools, stash a spare, and keep going.

Why Materials, Safety, and Distance Matter

Looking for a cordless train horn that holds up to daily use and real outdoor conditions?

We source real metal train horn trumpets and industrial-grade compressors because sound comes from good parts. Each unit is hand-assembled in the U.S., so we inspect every connection. Our custom PCB protects the motor and battery, and the remote range means you can trigger the horn from across a job site or field. That mix of portability, safety features, and authentic hardware is why people choose BossHorn.
