This app connects to a Z21 digital control centre. A demo mode is also available.
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 decoders as easily and conveniently as only touch technology can.

The Z21 digital control centre connects your model railway layout and your digital locomotives to your iOS/Android device via Wi-Fi. This allows you to control the operation of your layout easily and conveniently. Model railway control has never been so easy and casual: with a swipe, you can scroll through the locomotive library to the desired model. A quick tap on the headlight icon and the front and rear lights come on. A second tap, this time on the speaker icon, and the locomotive sound is activated. Then your finger briefly glides over the speed display and the locomotive picks up speed.

Other highlights of the Z21 app
• Control your entire layout via an intuitive, graphical touch interface – and access the full range of functions of your digital locomotives in just a few simple steps.

• Manage your entire locomotive library in a single application, including individual locomotive images for an optimal overview.

• Control the digital functions of your locomotives using intuitive function icons instead of complicated key combinations.

• Create a model of your railway layout and switch your points, signals, occupancy detectors and much more with just one click.

• Download driver's cabs and control your locomotives as if you were a real train driver.
