Train Horns Compatible with Hart Batteries

Our Hart-compatible Quad Pro is the loudest option we offer.

No, the color or finish only affects appearance. It doesn’t change the tone or volume.

No, the battery is not included. The Hart-compatible Train Horn is designed to work with Hart 20V batteries, so you can use one you already own or add a battery to your order as an optional accessory.

Yes, you can. Every Train Horn kit is fully compatible with all Hart 20V batteries, both original and aftermarket, so you can easily power it with the ones you already have.

Each Hart-compatible Impact Train Air Horn includes a wireless remote with a range of up to 160 ft (about 50 m) under normal conditions. This allows you to activate the horn quickly and safely from a distance.

A regular car horn is designed for everyday traffic alerts, while a Hart-compatible Train Horn produces a much louder, deeper, and more commanding sound. It’s built to stand out instantly and be clearly heard in open spaces — far beyond what a standard car horn can deliver.

All Hart-compatible Train Horn models — Dual, Quad, and Quad Pro — are available in three premium powder-coated finishes: Black, Red, and Chrome.

It’s not recommended. The wireless remote receiver draws a small amount of power even when the horn isn’t in use, which can fully drain the battery over time.

If your drill horn won’t be used for more than 5 hours, unplug the battery to prevent deep discharge and extend its lifespan.

Yes. Every Hart-compatible Train Horn — Dual, Quad, Penta and Quad Pro — comes fully assembled and pre-tested. Simply attach a charged Hart 20V battery, and it’s ready to use.

No tools, no wiring, and no setup required — just plug in the battery and you’re good to go.

With a fully charged Hart 20V battery, a Hart-compatible Train Horn can be used for many activations on a single charge. Actual runtime depends on the battery capacity (such as 2Ah, 5Ah, or 8Ah) and how frequently the horn is used.

A Hart-compatible Train Horn produces a very loud, sudden sound that may help discourage animals in certain situations, particularly in open outdoor areas. However, results can vary depending on the environment, distance, and the type of animal.

This product is not intended as a wildlife control device and should be used responsibly, in accordance with local laws and safety guidelines.

Hart-compatible Train Horns are designed to be water-resistant, but they are not fully waterproof. They can tolerate light rain, splashes, or brief exposure to moisture during normal outdoor use.

They are not intended for heavy rain, prolonged exposure to water, or full submersion. For best longevity and performance, we recommend keeping the horn dry when not in use and avoiding extreme wet conditions.
