ESU 50200 ECoS 2 Central Unit DCC Command Station
The ECoS 50200 is already the second generation of our successful ECoS command station. With the latest ECoS command station, ESU continues to offer state-of-the-art digital technology combined with contemporary functional range and easy handling all this for a fair price-performance ratio.
The ECoS has - like most of the recent central stations - a large coloured display with high resolution. In combination with its ground-breaking and easily operated user interface and excellent contrast values of the coloured screen, ECoS reaches unprecedented ergonomics: unlike all the other central stations, the ECoS can be also operated without a stylus - all symbols and writings are hugely marked and clearly structured.

ECoS has 9 function keys per integrated cab. The light-, and function keys 1 to 8 show the current state of the function via LEDs.
Discover the fascinating possibilities of the ECoS command station on the following pages. But take heed: ECoS performance is so good, that even we had to re-read a few passages to believe it!

ECoS Features

With an ECoS command station you acquire an open system. As is expected of ESU, from the beginning we wanted to be open to, and compatible with, present systems and norms. Just like our decoders, the ECoS is a real multi-protocol command station.
As a multi-protocol command station, 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. You can even continue to use almost all of your present loco decoders. ECoS is therefore the only digital command station worldwide that unifies 4 data protocols.
With an ECoS you can run locos: via two integrated cabs with large, easy-grasp motor driven throttle knobs and nine precise click-function keys you control your locos. In combination with the touch screen, you can control up to 20 functions per engine.
ECoS controls turnouts and magnetic accessories: a large, graphical control panel provides you access for up to 1420 turnouts (DCC or Motorola® protocol).
With ECoS you can plan and control routes: simply put turnouts and magnetic accessories graphically in groups and switch them together. Routes will be activated either by feedback contacts or by key. You can even use s88 occupancy detectors or ECoSDetector feedback modules.
With ECoS you can operate shuttle trains very easily: put a rail contact at both ends of the track and ECoS will do the rest.
The ECoS built-in booster has so much power that, in most cases, you dont need additional ones.
ECoS supports EcoSlink, a high-speed bus system, based on CAN, that transmits data instantaneously to the command station.
With ECoS, never before has it been so simple to program your decoders: the large, colored TFT screen offers good contrast and displays a lot of information in unabbreviated text. A programming track establishes contact with your decoders.
Of course, the ECoS has a pre-installed DCC RailCom® function: with its global detector it recognizes RailCom®-compatible decoders (e.g. our LokPilot V3.0 decoder) directly on the main track. You also have the possibility to feedback the turnout position via the SwitchPilot to the ECoS command station.
ECoS is compatible. Besides Selectrix®, Märklin®-Motorola®, and M4, ECoS speaks all variants of the DCC-Norm. With the integrated analog controllers (joysticks) you can even control the whistle of LokSound decoders, never before more precisely.

ECoS is expandable. Each ECoS command station sports a network port for connection with a computer. Thus you can update software or use a computer for operation.

Who needs ECoS?

ECoS is basically the command station for all. Beginners, who are looking for a simple-to-operate cab, will be at home right away: the large, graphic touch screen display shows all information in plain text; in case of doubt use the integrated help function. Never was it easier to switch to digital control. And ECoS runs DC or AC driven trains.
Even model railroaders, who alredy own a digital command station, should step up to ECoS: next to the extreme simple inputs, and the possibilities for route-and shuttle train programming, you will learn to appreciate the manifold programming features for decoders. You can connect your present equipment to the input of EcoSniffer, and continue to use it: you dont need to discard anything that you want to keep using!

Due to its enormous output-performance, the ECoS command station is recommended especially for operators of Gauge 1 or G layouts: at last you can run multiple trains without an external booster. Total interplay with our LokSound XL V3.5 decoders is matter of fact.
ECoS leaves the factory with extensive features: Two cabs with motorized throttle knobs and nine function keys each, plus a two-axis, center-click joystick each. With it, you can blow the whistle of the LokSound V3.5 decoder, analogically, almost as you would with the prototype, or, in the future, control digital cranes perfectly. A real and optimally placed loco selection key helps you to select the loco desired.

The large, coloured TFT display shows all information in plain words. There is a touch-sensitive screen that you can work either with your finger, or the provided peg.
Each ECoS command station integrates a 4A-steady-output booster. Conventional model railroad transformers dont have enough power, which is why we supply you with a stabilized 90 VA (!) power supply. The output voltage is adjustable from 15V to 21V. The Power aplenty for your layout!

Decoder programming takes place via a dedicated programming track. This is independent of the mainline and normal operation on the layout is not affected during programming. ESU takes this for granted.

The new ECoSlink high speed bus serves as communicator between systems. The bus can be connected to throttles (e.g. Märklin® mobile station® 60651, 60652), ECoSDetector track occupancy feedback module, Navigator stations, ECoSlink Terminals and other system components. ECoSlink is robust (up to 100 metres cable length is no problem) and extremely fast: Forget all others!

Each ECoS Command Station incorporates a galvanically isolated jack for s88 feedback modules. Track-occupancy information can be used for route- and shuttle train operation.

An ECoSniffer jack is provided for connecting old, existing digital command stations. A galvanically isolated jack for connecting DCC-conform boosters tops off the list of ECoS features.
Run locos

The ECoS command station can manage up to 16384 locos. Each locos 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 its  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 CVs 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.

ECoSControl Radio

ECoS is well prepared for the application of our wireless ECoS Control Radio remote control unit: A special receiver card fits into a module terminal, called ECoSlot. The ECoSControl Radio integrates perfectly into the ECoS-system and acts like a fully featured cable-bound throttle.


Of course all DCC conform boosters can be connected to the ECoS command station: There is a corresponding socket. Also, the widely known Märklin® 6017 boosters (or compatible products) can be used.  
Alternatively, you can decide on the separately available ECoS booster, which connects directly to the ECoSlink bus: As a matter of fact, it incorporates a RailCom® detector, so you can use their great features. The integrated M4 feedback function makes it possible that Märklin® locomotives with mfx®-decoders are recognized in the booster area.

Each ECoSBoost is controlled and configured most comfortably by the ECoS. Additionally, the display can be dialled up to show you the present power consumption of each booster, so you know how much reserves you still got..


ECoS offers a factory built-in galvanically isolated (!) s88 feedback interface for the very popular s88-modules. They serve as track occupancy detectors and may be used for controlling routes and shuttle train operations. An integrated s88-Monitor helps during the set-up and testing of your feedback modules.
In addition to this occupied tracks can be displayed within the ECoS track diagram.

ECoSDetector feedback modules

If you do not want to use the s88 system anymore or even replace it, the ECoSDetector is the perfect choice. It finally makes a reliable track occupancy detection possible. Beyond this, it recognizes, in combination with a  RailCom® compliant decoder, any loco on the controlled area.

L.Net Adapter

With the L.Net Adapter you can already use existing handheld throttles and feedback modules fully and bi-directionally integrate in the ECoS system. Thus nothing more should stand in the way of using Daisy®-, Fred®- or ProfiBoss® handheld throttles!

Dynamis® Pro Box

The Dynamis® system, which has been cooperatively developed by ESU and Bachmann®, offers an attractive possibility of expansion. This infrared based system can be connected to the ECoSlink bus via the Bachmann® Pro Box (available from Bachmann®).
Your ECoS provides up to 4 infrared transmitters, with which you are able to control up to 40 locomotives with 20 functions each, as well as magnetic accessories. The booster output can be used additionally.


Our bus system ECoSlink allows the extension of your ECoS command station. You may connect 128 external handheld unit throttles (e.g. Märklin® mobile station® 60651, 60652), ECoSDetector feedback modules, ECoSBoosters and other extensions.

ECoSlink is based on the CAN industrial standard, is suitable for a maximum cable length of 100 metres and provides excellent data transmission. ECoSlink operates with 250 kBit / second and is hot-plug and plug&play capable. All devices report automatically to the system and can be removed or reconnected during operation.

Mobile Station®

The most well-known device compatible with ECoSlink is the mobile station® of Märklin®. You are able to control up to 10 locomotives with the mobile station®.

Computer interface

The computer interface (according to RJ45 Ethernet standards) enables you to download updates, to save and recall all ECoS data on your PC (back-up). Above that, you are able to control your layout by a computer with the help of external controlling software or to have transferred the screen content to a computer.
