With this app you can manage locomotive libraries, locomotives and locomotive functions, program digital components - and of course control all locomotives with DCC- or Motorola-decoder, as easy and convenient as is only possible with touch-technology.

This way you can control the operation on your train layout easily and conveniently from your mobile device. Model train control was never this easy and convenient: With one swipe of your hand you can scroll to your model of choice in the locomotive library. A slight touch on the headlight symbol and the front and backlights go on. A second touch, this time on the speaker symbol, and the locomotive makes a sound. Drag your finger over the speed indicator and the train accelerates. The further highlights of the Z21-Mobile-App . Control your entire layout with an intuitive, graphic interface and have easy access to the entire scope of functions of your digital locomotives. . Manage your entire locomotive-library in just one application, including individual locomotive images for an ideal overview. . Control the digital functions of your locomotives with intuitive function symbols instead of complicated key combinations.
