Joined: 03/06/2008(UTC) Posts: 1,256 Location: Sydney, NSW		I have 2 Electric locos (39851 & 39374), both are less than 2 years old, and I'm having this problem. Sometimes, and nearly always, when I start each loco, they do move and when given a gentle push, they move until they are told to stop. I'm using TrainContoller with an ESU EcoS. Does anyone know why this is happening? Is there a special parameter in the CV's to adjust so this will rectify the problem? Awaiting your responses with great anticipation, Greg

Joined: 08/03/2006(UTC) Posts: 1,047 Location: Gold Coast, Australia.		Hello Greg, My friend Peter Chan had an "Adria" #39838 & it had this issue from brand new out of the box. We came to the conclusion it was the decoder / PCB board. He sold it "as is" as it was too expensive to return to Germany. I have to say we tried every know trick in the book at that time with no result. Sorry I have no more info for you on the cause of this phenomenon. I will be interested to hear if someone has come up with a simple solution on the matter.

I would look at the condition of the brushes, give the whole motor a good clean, and possibly check that the springs are pushing the brushes in strongly enough. The 39851 seems to have some kind of can motor? If this is the case it could be the first signs of the brushes wearing away. In most can motors this is terminal and the motor will need to be replaced. I have had to replace two can motors in my Marklin locos in recent years, but fortunately they are cheap and readily available.

Joined: 03/06/2008(UTC) Posts: 1,256 Location: Sydney, NSW		Thanks fellas for the advice. These locos haven't had a lot of use, therefore your suggestions to basically overhaul the motors and/or the brushes, is rather a drastic step. I will have a close look at the motors and brushes, but if they don't look worn or dirty, then I will return them to Marklin as they are still under warranty. If this is the case (me having to return them), then it will mean another 2 locos returned within a month. I'm really disappointed with Marklin's quality - I think it's going down hill fast, and if they don't get their act together soon, then they are going to lose a large customer.

I'm surprised that you consider checking brushes and cleaning motors a drastic step. I would consider this basic maintenance! You say these locos have not had a lot of use. Can you estimate how much actual use they have had in hours? Marklin recommends performing basic maintenance like oiling and greasing after 40 hours of use, but some locos arrive from the factory with too little oil or grease (or too much!) and may need attention before the 40 hours. By all means send the locos back if you feel there is a real problem with them, but don't be surprised if they get sent back to you with a note saying there's nothing wrong with them.

Awaiting your responses with great anticipation, Greg Is everything else - as e.g. sound - fine on these engines? The reason for asking is that there could be issues with the TrainController-Mfx combo. It seems as if the 39851 could run as DCC. That could be tested, and change the address to e.g. >300.

Awaiting your responses with great anticipation, Greg I did had same similar problem with other Märklin digital locomotives. They always start jerk in the first speed step. When i use ESU or Brawa digital locomotives there is no jerk when they start. I believe the problem are Märklins mfx decoder.

Try with a CS2 if you know anybody who has one or try another decoder if you have a spare. If same happening with two different locos could be the controller. No idea about train controller should this be the problem. Have you other locos that run OK.
		Take care I like Marklin and will defend the worlds greatest model rail manufacturer.

No idea about train controller should this be the problem. Have you other locos that run OK. Indeed, if I run in such problems, I detected "just need a bit of cleaning". And not only the tracks. I think always underestimated is the cleaning of the locomotive wheels. It is one reason I am searching now for a reasonable locomotive wheel cleaner. For the tracks I take the cleaning dwarfs from NOCH. They are hanging at a coach in every running train. Makes and keeps the tracks clean, but the loco wheels ... unfortunately not.

Trix have a brass brush arrangement - you would need a clip lead to the pickup shoe to get power to the loco.

An acquaintance of mine runs Trix and swears by it.. I use a LUX wheel cleaner - dear as poison, but is does a great job.. Make sure you order lots of extra felt strips..

I use a LUX wheel cleaner - dear as poison, but is does a great job.. Make sure you order lots of extra felt strips.. Indeed this is one of an uncovered niche by Märklin. Although in Goeppingen is a big brush company too. https://www.mink-buerste...o_cache/anwendungen.html They are producing all types of brushes. Perhaps they are to big for Märklin. Mink-Buersten wrote they are doing over 52 Mio € sales per year. I know this LUX wheel cleaner, but quite expensive with a price of 198 € per piece. https://www.besserepreis...d-digital-einsetzbar.htm I guess this you mean with your expression "dear as poison"? I guess the Faulhaber engine makes the price. Have a look here, where you get the "poison" https://www.sb-modellbau...;path=/00000003/00000491 Anyway, thanks for your short positive experience notes feedback. I start thinking to buy one LUX WheelClean sooner or later. But first I am wating for my shunting Croc.

I think I would avoid running the tyres against the brush though.

Joined: 03/06/2008(UTC) Posts: 1,256 Location: Sydney, NSW		Today I was able to examine these 2 locos. I removed the top cover and moved 2 wires very gentle so as to access the motor brushes, when both wires came away from their solder joints. The wires were barely touched, so I'm assuming that the solder joints were not very good and this could account for this problem of the locos sometimes needing a push. Very careless manufacturing When the repairs are done and I carry out tests, I'll let you know the results.
