Hello.

My new item has just arrived. It is used 39370. Because of this I have two questions.

1. It has a c-sinus engine. And I have to say I'm a little disappointed about how noisy it is. As it only starts to spins it is more noisy then standard central engine. I oiled it a little bit but it didn't helped much. Is there any way to make it quieter?

2. Lights. It has directional yellowish LED in front and red and the back. But it also has a "long lights" (is it the right word?). But this one works in one direction only. If I change the direction this light stays and red lights appears next to it. It looks quite awkward. Does this mean that decoder is damaged?

They are a bit louder than modern DC motors but quieter than the older DCM. Nothing you can do about it

I haven't looked up the manual but from these style engines when I used to own them, the long distance headlights were individually activated for front and rear - they do not change direction like normal headlights.

Therefore if you change directions, you need to turn the long distance lights off for direction 1 and turn them on for direction 2. Try the next sequential function key ( F2 and F3 maybe?)

Would you be able to describe the noise or post a video of it?.
Perhaps some foreign object has attached itself tp the permanent magnet inside the motor?

I would love to do it. Can I upload a clip here?

But as applor said looks like this is ok. It is noiser than central engine but a little quieter then DCM

Thanks franciscohg

I have got sound to the max and I can hardly hear it. Mine c-sine is like a tractor compared to this one.

I was surprised that you found the motor noisy, perhaps it is damaged.
All of my Big C sine motors runs great,
I made a video on a test stand

From my C-sine grey Franco-Crosti, I remember it has a kind of "electric power plant" sound at the first 1-3 speed steps - but it runs fine and it is a great motor indeed.

The 39370 had a very early C Sine motor. I think it was only the second model fitted with one, after the ICE-S Train, which was an evaluation model.
I no longer have one in my collection, but recall that is was slightly noisier than main production models such as 39573 and 39579 for some reason.
Also, I believe that a different function key operates the long or high beam headlights at each end, they are not directional.

It is exactly what happens with mine

This is true as well. I discovered it yesterday. Listen them on loud speaker.

I did some video yesterday as well.



Check this one closer from 14th second.



And this one shows that as I lift loco noise stops but wheels carry on spinning. But then it is quiet.

Wow that is quite odd.
It may not be the motor, remove the body again and turn the motor over by hand, it should feel very smooth with no obstructions, it should be very very easy.
Hopefully you will be able to feel something wrong or see where the noise is coming from.

I have a feeling it is a vibration of a body. The engine itself runs very quiet. But as soon as I drop it on a track this noise appears. If I only lift it by 1 mm, loco will still run but noise disappears.

I'm thinking about some kind of foam between body and a buggy.
What could I do to reduce vibration? Buggy seats on 4 points of metal. If I for example paint them with some kind of "paint" which will leave a surface covered this should reduce the noise.
What do you think?

I don't think that will fix your noise problem, but it might create a grounding problem from the chassis to the rails. I think that it could be a mechanical problem and if the motor spins as freely as it should, then I would suspect the culprit might be in the gear train.

Good luck and let us know what you learn.ThumpUp

I have almost all Märklin and mostly HO, although I do have a small number of Z gauge trains!
I have models from Era I to Era VI, but I try to focus on Eras I & III. Whoops, that one got away from me. Let's just say I focus on cool trains, regardless of the particulars :-)
So many trains and so little time.

I didn't think about grounding but I think you are absolutely right. Im afraid I will have to live with it. I'm also starting to think it's a gearing problem. One of a wheels is a little lose. It is a tiny tiny but this can make this noise as it starts to spin.
