The ECoS has a large high resolution colour display. In combination with its ground-breaking and easily operated user interface, ECoS reaches unprecedented ergonomics: unlike all the other central stations, the ECoS can be operated without a stylus – all symbols and text are large and clearly structured.

ECoS has nine function keys per integrated cab. The light and function keys 1 to 8 show their current state via LEDs.



ECoS supports DCC, Märklin® Motorola®, Selectrix® and the M4 data protocol. M4 drives and controls locomotives equipped with mfx® decoders without any restrictions. M4 is completely compatible.
