CTC system is a model railway control that is completely based on a WiFi network (WLAN). This app is used to control such a model railway.
Important note: Due to the special functional structure of the CTC system, you will see an almost empty screen after download and installation. The “life” only moves in with the registration or the operation of CTC modules (decoders).
CTC reinvents digital model railroading from the ground up. This puts us in the fortunate position that we only have to pay little attention to compatibility and can cut out most of the “old habits”. What this means for you in concrete terms if you already own a model railway can be read in separate articles tailored to different scenarios at https://www.ctc-system.de.
