Hi,

I have a Marklin 37740 lok,which all of a sudden started running erratic on my layout.Can not control speed just races off into the sunset on its own.I deleted the lok from my CS@,and tried to re-register.But it just races off at top speed.Spoke to my dealer and said it could be the decoder.I looked up the parts on the marklin website,but states decoder is no longer available.How could that be,the lok is only 3 yrs old? Good thing they don't supply parts for automobiles.
Any advice would be greatly appreciated.

Also I am interested in an Esu lok #31062.Any ideas where I might find this,dealers are sold out.

Thank you in advance Mike BigGrin

Decoders are constantly evolving, so there is no real need to keep old models in stock as they can be replaced by newer versions. However if the loco has extensive functions it is not such a trivial matter to just swap the decoder for a new model as the functions may need to be mapped to different function keys to match the original.

I would say it would be a good idea to send the loco off to Marklin or the dealer for repair.

ESU's V 60 is a bit like Samsung Galaxy Note 7: very difficult to buy a new one.

If your V 160 is out of warranty, then maybe buy a retrofit decoder from Märklin or ESU, with or without sound. Will be much cheaper than a Märklin spare part decoder.

Hi,

When a digital locomotive (decoder) is on an analog track it will switch to analog mode. This is probably what is happening. It can be that the decoder just "think" that it is. I'm more familiar with ESU decoders, and on them it's possible to turn off the analog mode. Check to see if that is possible on your locomotives decoder.

This Lok ran perfect until now?? I don't think it is possible to switch this decoder to digital.

My limited experience with decoders that "go" (die) is that FIRST the digital side of it goes but you can still run it in analogue.

Then the analogue side goes as well. I do not know for how long it will work in analogue, maybe forever.

As a result, it seems that you now have a loco with a life crisis: it's a digital loco but thinks it is an analogue loco and behaves accordingly.

An analogue loco on a digital layout takes off and you have no control over it.

The reason it takes off is that the digital tracks are on at around full electric power all the time, hence lots of power goes to the analogue loco. In turn, the loco then behaves as if it were on an analogue track with the transformer control moved all the way up (the way I like to run Marlin trains ... BigGrin ).

Try putting the loco on a true analogue layout and see what happens. I bet it will work just fine. You will be able to control it like any other analogue loco.

Careful, though, if you fool around with the decoder, you may lose the analogue side as well. I know, it happened to one of my locos.

Hope this helps.

Thanks for your great response,Wouldn't it be easier just to replace the decoder?
I don't know anybody with a analogue layout.

Testing on analogue is one test to see if the decoder is partially operational.
Swapping decoders with another loco could be another test.
If the problem is with the decoder then buying a new decoder will solve the issue. A silent decoder will do if you do not need sound.

No, but it seems ESU destroyed all that were returned (and probably also some that never shipped). Since the model didn't reappear I assume there was a design flaw they could not fix easily.
