Whether you're stepping into the world of model railways, or returning after years away, there's never been a more exciting time to build a model railway than today given the endless technological advancements in recent years.

At the forefront of recent excitement is Hornby’s HM7000 system — a game-changing innovation that uses Bluetooth technology to control model trains. Let’s break down why HM7000 is a leap forward...

 

What is HM7000?

Hornby’s HM7000 (also known as HM | DCC) is a new way to control your locomotives using your smartphone or tablet via Bluetooth. It's built on the reliable foundation of DCC (Digital Command Control) but throws out the 'old-school' physical controllers and replaces them with an app-based experience.

With the HM7000 system, you're in full control: speed, direction, lighting, and immersive locomotive sounds – all at your fingertips.

HM7000 system features

📱 Bluetooth control

No more wrestling with complex control units. The HM | DCC app (iOS & Android) gives you intuitive, wireless control over each locomotive and accessory. You can run multiple trains, activate sounds, or tweak lighting — all from your smart device.

🔊 Next-gen sound decoders

Hornby’s HM7000 TXS (Triplex Sound) decoders bring your layout to life. Steam engines chuff, whistle, and brake authentically. Diesels roar, idle, and 'notch-up' just like the real thing. If you want to customise a decoder, just upload a new sound profile through the app!

🔋 Stay-Alive power banks

Worried about dirty track or power dropouts? The optional 'stay-alive' feature means your locomotive rarely (if ever) stutters or loses sound when passing over points or gaps.

🔄 Simple firmware updates

Hornby continues to refine the HM7000 experience. With over-the-air firmware updates, your decoder can stay up to date with the latest features.

Designed for all

The HM7000 system is designed for ease. Whether you're new to DCC or returning from the world of DC, this is the perfect way to modernise your railway without rewiring everything from scratch.

Choose a compatible decoder from our options, plug it into your locomotive (six-, eight-, 21-pin or Next18 available), download the app, and you’re ready to go.

 

Compatible and flexible

Already running a DCC layout? Good news — HM7000 decoders are compatible with traditional DCC controllers. Prefer Bluetooth? Use the app. Want to switch back? Use your DCC handset. You're never locked in.
