Grow your Hornby TT:120 layout

We recommend the HM7000 system as it makes use of Bluetooth technology. You get all the benefits of DCC control, without being tethered to a fixed point. To use HM7000, start by ensuring your locomotives have the correct decoder inside them. Some of our models come pre-loaded with a decoder, while others are DCC-ready, which means you'll need to buy and insert the decoder yourself.

You can then download the free HM|DCC app on your smart phone or tablet. Connect to your locomotive by following the instructions in the app and you'll open up a whole new world of model railway control.
