The train was listed as new, I guess it’s part of an estate sale but when I opened the package it had a burnt smell. I removed the housing and indeed found a scorch mark on the board, so I’m assuming this is why it’s not running. I contacted the seller so I’m not sure what will happen, but if I decide to keep this locomotive, what decoder would be a good replacement, it has a Sinus engine, the one with the bell housing, I recall seeing something that it can be tricky to replace a decoder when this engine is involved. Guess it wasn’t so new after all, I just hope the motor wasn’t damaged as well. Thanks Mike

Once you get all your money back you and the seller can decide what the end will be. Fixing it might be more than it is worth. And you do not know how much it will cost.

The motor is not seized, it moves very freely as would be normal with this type of motor, I have a couple other engines with this motor and they move the same. Here is the motor which is in the locomotive.

You should ask the seller to accept a return and refund the purchase price. If they are not willing, file a claim with eBay. Beware the seller may claim that you damaged it when you first tested it Regards Mike C

The engine is in brand new condition but as you said, the question is if I can get it running again. If they don't go for what I'm offering, then I will send it back. Thanks Mike Quick update, the seller agreed to my offer so I'm keeping the locomotive, now I just have to find a way to fix it, as before, if anyone can tell me if there is a decoder which would work with the motor in this engine, I'd greatly appreciate it. Thanks. Edited by user 05 April 2025 05:17:38(UTC)  | Reason: Not specified

(you might need to replace the bogie, but that might be expensive)

(you might need to replace the bogie, but that might be expensive) I think you're 100% correct that the driver is faulty or in this case it was damaged. I've been spending a fair amount of time on Google and I came across a post on the group where someone had the exact same train and said there is a voltage problem and this is a know issue with this driver board. This person chose to go the route of fitting a conventional motor by replacing the bogie, so probably as you said, expensive. I also found a post about the driver you mentioned from Rail4you, I'm thinking this is the route I will probably go cause I'd like to keep the Sinus motor, just hope that the voltage issue didn't damage the motor. Would you know how much the driver from Rail4you costs? Thanks Mike

(without shipping) I also forgot to mention that the driver is a bit sensitive to power interruptions so a power pack is strongly recommended. The c-sinus motors seem to be more "robust" than the original drivers, and my first-generation C-sine motor survived my soldering etc. (the motor in 39710 does not have flat cable) I'm happy with how my 39710 now drives, even if the upgrade was a bit expensive.

Which is the power pack you are referring to? a better phrasing is a buffer capacitor etc, you can make a basic one or use the 60974 or use the ESU ones etc. a little tip if you are using an mSD3, you make one yourself and use the susi plug. see: https://www.mittelleiter-magazin.de/uncategorized/susi-schnittstelle-fuer-puffer-schaltung-nutzen/

See old topic https://www.marklin-user...39&SearchTerms=39572 I was a little surprised that there didn't seem to be too much interest in this locomotive on eBay, after reading through the messages when this was first released, I can understand why, guess everyone knew about this isssue except me . What did you end up doing with the replacement Marklin sent you which also burnt out?

Joined: 09/05/2006(UTC) Posts: 128 Location: ,		Since I've dissected the locomotive further, I've found the driver board is scorched as well, is it possible through all of this that the motor could have been damaged as well? I don't want to order a new driver from Rail4you just to find out later that the motor is shot too. Thanks Mike

Given the driver board is no good and the motor has a ribbon cable, I don't understand how a battery could be used with this setup.

I own the early br 103 with it. I love it and would be sad if it died. Single row of vents, old pantographs not piezo, engine room lighting, and a whistle. TEE livery.

I know what you mean, I have the same engine along with the 103 with the automatic pantographs and I love those engines but after what I'm seeing with the 39572, I'm really worried if something happens to either locomotive, how do I fix them? Worse yet, including the E03 and 103, I have 3 other engines with that motor. It seems like a lot of people who purchased the 39572 had this issue, I'd be interested to find out what Marklin ever did about it, did they let everyone hang or did everyone just send them back for a refund?

I have seen so many people post engines on E-Bay as new when they are 30 years old and the seller is not a dealer. The only engine thats new is one you get directly from Marklin or a Marklin dealer and has not been used at all. Lightly used second hand engines in their original packaging may be nice, but they are NOT new! E-Bay should really put a stop to that practice.

Joined: 09/05/2006(UTC) Posts: 128 Location: ,		I've been spending a lot of time trying to figuring out how to fix this locomotive. I was initially going to get a driver board from Rail4you but without being able to test the motor to ensure it's not damaged, it would be a very expensive exercise in trial and error. I started looking on eBay to see how easy it would be to find a replacement motor, well, that was an exercise in futility, couldn't find one with the same part number but eBay gave me a suggestion, there is a motor from a company called Mircromotor.eu which is supposed to be a direct replacement for the C Sinus motor, was wondering if anyone here has tried using this motor. Here is the website and part number is HM001G: https://micromotor.eu/Mo...ts/H0-Gauge/Maerklin-H0/

Joined: 28/11/2007(UTC) Posts: 8,216 Location: Montreal, QC		I have heard of some modellers who have replaced the large sinus motor (C-Sine) with the normal motor from subsequent models of the same locomotive type. You would need to remove the motor, the PC board and replace both with the parts from the non c-Sine version. I am guessing that this job would require experience with this kind of work and is not something that a beginner should undertake. Micromotor.eu might be an option, but I don't know what you would need as far as a PC board. Regards Mike C

So I stripped it all & I got a second hand front bogie & fitted a high propulsion motor & made up a board as in the picture & fitted a Lokpilot M4 decoder & it runs as sweet as & not expensve to convert. In one of the pictures you can see the damage to the board & why I did what i did. Parts for this loco are very hard to come by. The only sound it made was that of a horn & I retained that sound board seen in the picture. [img][/img] [img][/img] [img][/img] [img][/img]
