decoders send their own available functions to the controller). The new protocol was incompatible with the earlier version but Central Station could be set to send either protocol to any decoder so older locomotives could be controlled alongside mfx equipped locomotives. The Central Station incorporated all functionality of the earlier keyboard, memory, and interface modules as well as being able to control up to 8 automatic shuttle (point to point) trains. The hand held Mobile Station 60652 was also offered which has a single locomotive controller, small LCD screen, and 9 function buttons. This unit could be used on its own as a low cost digital controller with up to ten locomotives in its own database or plugged into a Central Station as an additional controller. In 2008 Märklin announced a new second generation Central Station 60213 with colour display and enhanced features, this unit developed by a different contractor. The Central Station was re-numbered to 60214 a few months later, with more capabilities than 60213. In 2009 a software update for the CS2 was announced which, among other enhancements, adds support for the NMRA DCC protocol. Also in 2009 a new 60653 Mobile Station was announced, completely redesigned with many more features than the earlier model. As before, the new Mobile Station can be used by itself or as an additional controller with the new Central Station. In 2016 Central Station 3 was announced. The main change is a new touch screen which replaces all of the function buttons with on screen options. Only the two speed controllers and emergency stop bar remain as separate controls. Central Station 3+ adds the ability to act as a master unit in a multi controller set up. Decoders Decoders are designated mfx and can communicate with the controller, dynamically negotiating an individual address and passing the locomotive description and all available functions to the controller. All control parameters are retained by the decoder in firmware and adjusted using the controller or computer. mfx decoders can also interpret the older Motorola format and so will work with previous central units. Early Problems Märklin experienced compatibility problems with the first Central Station (CS1) leading to a recall and extensive rebuild resulting in CS1 V2. Meantime some important components, especially an mfx compatible booster, were unavailable. Eventually booster 60173 became available for use with any mfx system. ESU, the original developers of CS1, produced V3
