I am a bit confused with the range of Marklin's decoder range 60940, 60945/6/7 and 60965/6/7. To cut the long story short I have the following questions: 1. What do mLD and mSD stand for and what are their differences? 2. In what situations are the 60940, 60945/6/7 and the 60965/6/7 decoders being used? 3. What is the difference between 21 and 8 wires decoders? 4. I have several old locomotives that I have converted to digital with the 60760 digital high efficiency propulsion set. Which sound decoder should I use to add sound? 5. Why doesn't Marklin dedicate a page in the catalogue explaining the above? I would appreciate if you could help me figure out what is what

Hi!
1: mLD: Lok-Decoder (no sound), mSD: Sound-Decoder
2: 60940: mSD with NEM 660 decoder socket to replace ESU decoders in Märklin locos; 60945/6/7 are not compatible with NEM 660 and can be used for newer locos; 60965/6/7 come with a NEM 652 plug in the box (not wired to the decoder) and can be used for locos with NEM 652 socket or no decoder socket at all (solder decoder wires directly to the loco).
3: see 2.
4: Any. If you want Märklin decoders, better use 60945/6/7
5: I dunno (documentation often is their weak spot anyway) |

Great question that I have been struggling with as well. I can help out a little bit, but the digital experts will need to answer to the most part.
1. mLD I assume stands for Maerklin Lok Decoder (no sound). mSD I assume stands for Maerklin Sound Decoder (it does have sound)
2. The 60945 is an mSD that is preprogrammed with a steam locomotive sound and 21 pin connector, the 60946 is the same but with a diesel locomotive sound, and the 60947 is the same but with an electric locomotive sound.
I see that HO has also now replied so I will stop.

[Some Additional information:
The new decoders:
60942, mLD, multi protocol decoder (mfx, MM1, MM2 and DCC) with an amplifier board, six function outputs
60962, mLD, multi protocol decoder (mfx, MM1, MM2 and DCC) with wires and an 8-pole NEM connector, four function outputs
6094?, mSD, multi protocol sound decoder (mfx, MM1, MM2 and DCC) with an amplifier board, six function outputs and speaker
6096?, mSD; multi protocol sound decoder (mfx, MM1, MM2 and DCC) with wires and an 8-pole NEM connector, four function outputs and speaker
The sound decoder's number last digit: 5 is for steam engines, 6 is for diesel and 7 is for electric locomotives.
The mSD decoders 60948 and 60949 has special amplifier boards suited for the 36-series Hobby locomotives with bogies. 60948 for diesel engines and 60949 for electric engines.

Modestly, just a quote from my own web site. |

Thanks Tom, Svein and Peter.
1. I am trying to understand by reading the manual of the 60945. If I get it correctly both 60945/6/7 and 60965/6/7 are digital decoders AND sound decoders. Right? If the loco has already have a digital decoder should it be replaced?
2. How can I know if the loco has a NEM 660 or a NEM 652 socket? I had a look at a few manuals but they do not mention it. OK, opening it and looking inside is an obvious answer but is there any other way?
I truly appreciate your help :)

The sound decoders replace the previously installed decoder. Only very few Märklin locos (from around 2004) have NEM 652 sockets. All mfx locos and most recent fx locos have an 21MTC socket. If the loco has a blue mfx decoder, then assume NEM 660. Green decoders are most likely not NEM 660 compatible, red decoders are never NEM 660 compatible. Also check the ref. number lists in the 60940 manual. Manual can be found here (copy URL to address field): Vary the number for other manuals. To be on the safe side, open the loco. |

Question, the 60954 sound decoder for steam lokos- Can you adjust the time between "chuffs" so the sound is synchronized correctly based on wheel diameter and number of cylinders? Ie: proper number of chuffs per wheel revolution.
Edit: found them CV 57 and 58. |

Era 3
DB lokos, coaches and freight cars from across Europe
But I do have the obligatory (six) SBB Krocs
ECoS 50200, all FX and MFX decoders replaced with ESU V4s, operated in DCC-RailCom+ with ABC brake control.
With the exception of the passenger wagens with Marklin current conducting couplers, all close couplers have been replaced with Roco 40397. |

One item not covered above is the number of functions and current rating limitations While some of the documented specs may be at odds (English section different from German section) the 6094x items have 4 extended function capability while the NEM 6096x (i.e NOT 60960/1) only have 2 The current ratings per port are the same , 250mA except for Aux/3/4 for the 60940 which have a note against their 20ma indicating logic only. |

Hello, You have to check the space available inside the boiler/tender also. The 60945/6/7 will occupy larger space than 60965/6/7, and most of Märklin steam loco don't have enough space for 60945/6/7, especially BR 24, S3/6, Gt 2x 4/4, T18 and B VI (I converted this loco from delta/analog to digital). If you planning to convert a delta/analog loco into digital, better to open the loco first, and check the space available inside the loco. Good luck! cheers, Sony
