Digitalisation of model railways is no longer in its infancy. You can control your locomotives with a controller, a PC or laptop, or even with your phone or tablet.
Roco's Z21 platform is one of the most innovative systems for digital control. Buying a Z21 means you have a fully-fledged digital control centre aimed at the future in your home. The system combined with the Z21 app turns your device into a comprehensive and graphical control controller for your model trains.
