Märklin 60976 mSD/3 Diesel Locomotive Sound Decoder with Circuit Board

The Märklin 60976 mSD/3 sound decoder replaces the standard circuit board in select Märklin/Trix diesel locomotives, adding full mfx+ functionality and a rich diesel soundscape without needing a separate decoder. Unlike generic decoders, this unit is tailored for specific models, ensuring a clean installation and optimal motor control.

Highlights

• mfx+ capable with up to 32 controllable functions
• Extensive diesel sound: engine noise, horn, braking, compressor, shunting, station announcements
• High-efficiency silent motor control with load compensation
• 8 function outputs for lights, smoke generator, and auxiliary functions
• Integrated circuit board for direct replacement in compatible locomotives

In daily use

The decoder operates on Märklin Motorola (MM1, MM2), mfx+, and DCC systems, with RailCom compatibility and a SUSI interface for expansion. Programming is straightforward via Märklin Central Station, Mobile Station, or any DCC controller using CVs.
