Does Milwaukee make a train horn?

No, Milwaukee doesn’t officially make or sell a train horn. However, there’s a product called the Milwaukee Train Horn by BossHorn that uses a genuine Milwaukee M18 impact driver as its base. BossHorn takes brand-new Milwaukee tools and handcrafts them into fully functional, portable train horn guns that are ready to use right out of the box. 

What Exactly Is a Milwaukee Train Horn?

The Milwaukee Train Horn is a high-powered air horn system built inside an authentic Milwaukee M18 impact driver body. It features a metal trumpet system, a built-in air compressor, and a remote-controlled activation module. The result is a handheld horn that produces up to 150 decibels of sound — as loud as a real freight train.

How It Works

• Power Source: Uses any standard Milwaukee M18 battery — OEM or aftermarket.
• Operation: Works instantly once the battery is connected — no air tanks or extra setup needed.
• Control Options: Can be triggered either with the tool’s original trigger or remotely (up to 160 ft, or 2000 ft with a long-range remote).
• Sound Output: Reaches around 150 dB, easily heard from over a mile away in open conditions.

Why It’s Popular

The Milwaukee Train Horn stands out because it combines Milwaukee’s rugged design with BossHorn’s attention to detail. The metal trumpets look professional, the finish is durable, and the overall build quality feels like a real factory-made product — not a cheap modification. It’s portable, rechargeable, and doesn’t require any installation or extra equipment.

Available Versions

• Dual Trumpets – Compact, lightweight, and powerful.
• Quad Trumpets – Louder, with a deeper tone and balanced power.
• Extreme Series – The loudest version, with a deep, low-frequency rumble that sounds closest to a real train horn.

Safety and Battery Care

• Always wear hearing protection — the horn’s sound can cause hearing damage at close range.
• Use outdoors only — never in enclosed areas.
• Disconnect the battery if the horn won’t be used for more than 5 hours. The receiver draws a small standby current.
• The horn automatically shuts down its receiver after 3 hours to protect the battery from deep discharge.

The Bottom Line

So, while Milwaukee doesn’t make a train horn themselves, BossHorn does — and it’s built from an authentic Milwaukee M18 impact driver. It’s one of the most powerful portable air horns available, producing up to 150 dB of real train sound with the convenience of a rechargeable tool platform. If you want something that looks like a Milwaukee tool but sounds like a freight train, the Milwaukee Train Horn by BossHorn is exactly what you’re looking for.
