New for 2024

With the ECoS ESU Command Station 50220, we are pleased to introduce you to the latest generation of our successful ECoS digital center. The ECoS offers you the most modern digital technology and a range of functions that is unique in the model railway industry, with which both (new) beginners and “experts” who are looking for a new headquarters will not be disappointed. Operating the device is child's play thanks to the large color display with touch panel and the coordinated user interface: All symbols are large and clearly structured, information is displayed in plain text in different languages.

The ECoS control center contains everything you need for digital system operation: Simply connect and get started.

What does an ECoS offer you?

With an ECoS center you acquire an open system. It has been designed for the greatest possible openness and compatibility with existing systems and standards. As a multi-protocol center, ECoS supports the data formats:

  • DCC with RailCom® and RailComPlus® (up to 9999 addresses, 128 speed levels, 32 functions)
  • Märklin® Motorola® (up to 255 addresses, up to 8 functions)
  • Selectrix® (driving operation and programming of the decoders)
  • M4 (mfx® compatible, with automatic registration of the locomotives)

The ECoS is therefore the only digital center that offers all four common digital protocols. This is important so that you can continue to use almost all existing locomotive decoders.

With ECoS you can control switches and magnetic accessories: The graphic switch control panel gives you access to up to 1200 switches (DCC or Motorola® format).

With ECoS you can create and trigger routes: Group several switches and magnetic accessories in the simplest, fully graphic way and switch them together.

With ECoS you can control shuttle trains.

To connect external digital components, each ECoS is equipped with the ECoSlink, our CAN-based high-speed system bus. Each ECoS center also has a network connection for connecting to a computer.
Thanks to the booster integrated into the ECoS and the included switching power supply, you can get started straight away! You don't need anything more!

Who is an ECoS suitable for?

Basically, an ECoS always “fits”: beginners who are looking for an easy-to-use control center will find their way around straight away: the large graphic display with touch panel shows all information clearly in plain text. Switching to digital has never been easier! ECoS is equally suitable for DC and AC railways (assuming a suitable decoder) and all gauges from N to G.

Model railroaders who are looking for a new digital control center are also in the right place with the ECoS: In addition to the route control and the shuttle train control, you will learn to appreciate the easy operation of the device and the extensive programming options for decoders.

You can connect your existing digital system (e.g. Märklin 6021®, Lenz Digital Plus®, ROCO®) to the input of the ECoSniffer and continue to use it as a hand controller. It becomes more convenient if you want to switch from a Loconet® control center (e.g. Intellibox, Digitrax®) to the ECoS: The optional L.Net converter integrates these devices perfectly into the ECoS.

Function Details

Run locos

The ECoS command station can manage up to 16384 locos. Each loco’s characteristics are memorized, so in the future you can call each engine by name. Also you can assign a loco symbol and these symbols keep you abreast of the function of each loco, regardless of whether it’s  latching or non-latching. An extensive navigational menu takes care of finding your locos quickly; and running them.

Of course, ECoS supports all DCC addresses (upt to 9999) and 128 speed steps, during Motorola® operation up to 255 addresses and 27 speed steps are possible, depending on the decoder´s features. Locos equipped with an mfx® decoder will be recognized automatically by the ECoS and can be driven without any restrictions.

Operate turnouts and magnetic accessories

Just like with locos, you can name turnouts and magnetic accessories. The large control panel on the screen of your ECoS shows you all turnouts and their switch-position. You can put turnouts in the depot area and to each magnetic accessory you can assign its exact function, so you can tell simple-, double or 3-way turnouts apart from de-coupler tracks or even streetlights, etc.

Turntable control

It is possible to control the well-known Märklin® turntables graphically with the ECoS command station; ECoS is able to control the specific Märklin® decoder directly. If you do not wish to use this decoder, you can simply convert your turntable via a LokPilot V3.0 decoder. We offer a substantial manual that describes how to do it.


Several magnetic accessories can easily be grouped as routes. Routes can then be switched like singular turnouts or they can be tied to an occupancy detector: Thus extensive block-control management is possible already. ECoS can manage up to 1024 routes with up to 256 magnetic accessories each.

Track plan

If desired, a fully graphical track plan shows the topology of your layout directly on screen. Put all signals and turnouts directly off the track plan. Even larger layouts can be displayed on the track plan, as it may consist of up to 99 pages. The pages can be arranged and renamed individually. The magnetic accessories shown on the track plan correlate with the ones that are placed in the accessory control panel; so it´s up to you how and with what you switch your magnetic accessories.

Shuttle train control

Shuttle train control, which was introduced with the first ECoS, enjoys an increasing popularity due to its simple handling: here you only need an occupancy detector at each end of the track, which you assign via Software to a loco: length of layover, acceleration - and deceleration, or in-between stops can easily be programmed on the ECoS screen. This works with any decoder because the brain of the system sits in the central unit. Up to eight shuttle trains are possible.

Decoder programming

Thanks to the screen, programming  decoders is as simple as never before. All parameters are shown in plain text. The search for / of CV’s and bits and bytes is a thing of the past. Of course you can call up and check all features of your decoder (during operation on the layout) on the main. POM (programming on the main) makes it possible. The addresses of your old Motorola® decoders are ascertained automatically - never again do you have to take your engines apart and check the DIP switch.

Keep using old systems

We make your transfer to ECoS as comfortable as possible: simply keep also using your “old” system. This is made possible through the built-in EcoSniffer:  The rail output of your present digital command station is simply connected to the input of the EcoSniffer module. The module listens to all DCC and Motorola® packets and translates them for the ECoS command station. This again treats your old system like one (or more) additional throttles or keyboards.
