Multi locomotive control Central Station


Playfully set, go and configure. This allows the electronic multi locomotive control from Märklin (world leader in the model railroad market). Coolgrey conceived the user guidance for the device and designed the graphical user interface. Complex model railroad systems are easy to handle with the touch-screen application. Both, young and old customers, are filled with enthusiasm about the consistent operation logic and clear design.

In particular, we are pleased about the feedback from users, who are able to use the complex system intuitively and without a manual.

Child's Play

»2 years hard development work with the participation of design specialists have produced a device which is so easy to handle that you will simply be amazed.«

Impressive clarity

»Despite the high resolution color screen colors were although sparingly as well as accentuating used. Thereby, they reached an almost irresistible clarity in the assignment of functions.«
