The loco starts to move and stop, all the sounds works properly.

Already check the conections and try 2 different controllers, both with the same problem. Other loco runs normally at the same circuit.

Video attached correctly now (first in English, second in Portuguese)

Is it Marklin? Too little information to provide any help. Did you try using a 9V battery to operate the motor? And what controller do you have?

Hi!

Welcome to the forum.

There is no video attached.

Märklin 39250 is the Swiss Elephant with mfx. 39250

This is like going to your new doctor for the first time and saying 'I'm ill'
I don't want to be rude, really?

The user has a CS and what appears to be a black MS2. He states that sound and lights work, but that none of his locomotives will move more than perhaps a stutter.

Here is my recommendation. Set up a test track made up of 4 to 6 straight sections
Connect one or the other controller
Run through a test of all functions, including lights, sound and motor

It is possible that the motor of one locomotive might be blocked/gummed up, but the chances that this would happen to multiple locomotives at the same time are much lower.

I am not a CS expert. I have a few MS2 that I use.

Not sure but are you saying that it is only one loco that does not work but all the the work as they should. If this is the case then the track and contoller are OK. Check the slider on the loco to enure it is straight and makes proper contact.
Take care I like Marklin and will defend the worlds greatest model rail manufacturer.

I cleaned all the contacts and the problem continues. Here's a video to show better. WhatsApp Video 2025-07-26 at 21.45.27.mp4 (2,998kb) downloaded 11 time(s).

Do you have it set up on a route or recording etc on your CS2 which my not be set properly. Unlikey though. Can you replace the decoder. AS asked above did you try with battery.
AS you have checked the slider and cleaned everything I can only think the fault is with the decoder or motor.

I'm not sure the battery test works with such a modern loco.

It is unlikely that the decoder is not pushed down all the way, but I'd inspect that. It is probably in the tender.

If the loco no longer runs, but lights and sound are still working, then maybe one collector of the motor lost contact. To test for this, I'd open the loco and gently give the flywheel at the motor a quarter of a turn. Then apply power again and look if it gets moving.
Never try to turn the loco wheels by force.
If it moves again, then maybe a longer run-in is all it takes. If the issue shows again and again, a new motor may be required. A dare-devil might open the motor to fix it.

I did have same similar problem but it was digital protocol that was problem.
So i decides to use mfx instead and the loco did start move.
Strange but could be ghost problem for short moment.
The loco did start work normal again with the DCC protocol.

DCC = Digital Command Control
