Now add "mfx" capabilities to your Marklin Central Station !!!

Indispensable components of any large model railroad are amplifiers (here called 'Booster'): If the power consumption of all of your moving trains including their functions, car illumination, and function models is larger than the current the central station is able to put out, you have to split up your layout into several blocks, the power for which is supplied by their own booster. The ECoSBoost(er) is designed for precisely that task: It is matched perfectly for the use with our ESU ECoS or the Marklin central station. The ECoSBoost is being offered in two variants: The 4 Amp version is perfect for HO and smaller, while an 8 Amp version is suitable for the garden railroader. Just like ECoS, each booster comes with its own suitably dimensioned power supply.

Mode of operations

The ECoSBoost is connected directly to the ECoSlink jack, from where it gets its control signals. Basically it is capable of amplifying and delivering to the track these data formats: DCC, Motorola, Selectrix and mfx. Which data format will be put out in a given case, depends of course entirely upon the command station that's being used, and its capabilities: Therefore the booster, connected to an ESU ECoS, will handle DCC, Motorola and Selectrix, while, if attached to a Marklin central station, it will amplify and deliver Motorola-, respectively mfx data signals. Thanks to 'Plug&Play', all ECoSBoost(ers) are included automatically into a list of extern ECoSlink components, and can be controlled and configured centrally on the ECoS display.


ECoSBoost amplifies data signals generated by the digital central station, and delivers them to the designated track outlet. Depending upon model, there are 4, respect. 8 Amps continuous current available. Subject to current draw, the 4 Amp version, designed for HO and smaller, can handle up to 10 locos. ECoSBoost power comes from an included power supply, featuring a stabilized DC output. Each ECoSBoost is controlled and configured comfortably directly by the ECoS: For each booster you can individually determine its max permissible output current. What's more, the display can be dialled up to show you the present power consumption of each booster, so you know how much 'reserves' you still have. Extremely sensible is the option to tell each booster individually, weather or not to shut down its section in case of a layout short circuit: If, for example, you have your switch (turnout) decoders hooked up to a separate ECoSBoost, you can still control your switches reliably in case of a track short.


An ECoSBoost can do more than amplify and deliver track current: Each one has incorporated, as a standard feature, a feed back function (Global Detector) for the NMRA Bidirectional Communication. With its help, appropriately equipped locos can send back information to the ECoS, as soon as the relevant DCC  norm is adopted. This is immensely helpful in finding the loco's position on the layout, or reading out engine data. ECoSBoost reads the data and sends them via the ECoSlink high speed bus to ECoS for further processing. 

M�rklin� central station

Connected to a Marklin central station, the ECoSBoost commands a similar function: All mfx locos supported by an ECoSBoost behave exactly as if performing directly with a central station, and of course can register them selves or transfer configurations changes.


Each ECoSBoost of course meets the relevant requirements regarding safety and operation on a layout: The track outlet is protected against overload as well as short circuits. Of course ECoSBoost can differentiate between a 'genuine' short, and a momentary current drain when passing over switches or gaps. We place value on the indestructibility of the device, just like we do with our mobile decoders.

 Future built in

The operational software of each, in an ECoSBoost integrated micro controller can be updated, of course, if need be, and augmented by additional functions:

The required upgrade is performed automatically by the ECoS central station, if necessary. No action on your part is required! In this way your ECoSBoost is literally always 'up to date'!
