Archive – Historic Digital Control

Welcome to the archive. Our older models have earned more than just a nice place in our memory. Märklin Systems and Delta have proven their staying power here. Modern components of the Märklin Digital world are compatible with the older models. This makes this archive with its systems informative and timeless..

Märklin Systems – More Locomotives, More Functions.

Märklin Systems was the "next step" in model railroad control. The Central Station equipped with a touch-sensitive graphic screen replaced the 6021 Control Unit of the previous Märklin Digital system. When they were introduced at the start of 2004, they established a new level of digital model railroad technology with numerous new functions, automatic locomotive registration in the mfx system, and interactive operation.

The starter area also profited from Systems and mfx. Equipped with clearly more possibilities than the Delta System, the "Mobile Station" of today represented a powerful basis for a challenging digital start as well as for train operations on medium size layouts.


With it, you directed a large number of trains on one and the same track layout. You literally set the tone: sound effects, lighting, or special functions on your models, you have them enjoyably under control thanks to real Plug & Play comfort. Yet as a model railroader's requirements regarding comfort and variety increased, the development followed these wishes. A new milestone was set in September of 2008 with the introduction of the new central units from Märklin Digital. This new Central Station was clearly more powerful than the previous Systems model and it would therefore replace it. Information for software downloads for the owners of the Systems Central Station can still be found here. Please visit the Systems service page for this.

Software and Service for Märklin Systems

Software was naturally of central importance for the digital components in the Märklin Systems program for their function with each other as well as for communication with the user. Here in the Download Area you will find all of the data and documents to keep your devices up-to-date.

Here you will find in a PDF format a listing of locomotives and powered rail cars as a database that is stored in the background in the Mobile Station. Since the complete summary of the Märklin digital history is not a simple task, there may still be changes to one or the other items. We will document these changes with updates to the database list.
