Okey folks!
I did tested my locomotiv and it´s great machine!
Here is verified what i so far react about this model.
The cardboard is impressive and nice,but seems little to much for an locomotiv.
Inside there is an wooden box,which is totally waste.
But when i did open the wooden box,there was she!
It was already impressive to see her in the package.
When i did open the package,she did appears.
What an sight!
The manual is okey,but there is some missing information.
There is no info about CV50 adress,which stands for to adjust value of analog AC,DC,MM and mfx protocol to derailment by program.
I was forcement go to Märklins homepage and click on the technology information to download decoders CV list.
Finally i did put locomotiv on the track and did start program first to find locomotiv and adress is standard at 3.
Writed name of the locomotiv.
Done!
Did started scroll up speed knob and she runs.
Test lighting on and that is impressive,but a little bit too much yellow brightness(should reduce flash of light).
Test sound on and holly smoke,what an impressive sounds!!
She is running excellent.
The decoder did standing first at 126 speed steps,but i see this to much so i did changed to 28 speed steps.
The details is fantastic and it´s already impressive to see finish color and details.
The only missing is locodriver and fireman.
Of course...smoke generator too is missing.
Märklin/Trix has done an nice work with this locomotiv.

Nice loco Anders
She is now higher on my wishlist.....i need some company for Tristan and Klopstock!!

I did found out some strange structured with this locomotiv.
It has 4 traction tyres!
And wheels on the tender don´t have all contact on the track.
If i did had Märklin same model,all the wheels have contact on the track while pick up shoe on the stud contact.
Big difference...but why did Trix add four traction tyres on an DC locomotiv,i don´t get it!

Now i have problem with the mfx decoder.
It don´t work as it should do with the sound.
Sigh...

I take back what i did wrote!!
Mfx are crap!!!
Just only total 2 hours of driving with the locomotive since i did bought it,mfx sounds doesn´t work it should.
I wish Märklin could produce analog locomotives with 21 pole schnittstelle,so i could choise ESU sound decoder instead.

Sure!
The sounds keeps on when i did shut the functions off.
Sounds dissapear when i did change the direction and start speed up.
Both steam and the squel brake is the problem.
I did reset the decoder and did happens before too.
It´s not helping anyway!
There is no faults with the MS2,so it´s decoder.
Never mind...i did learn the mistake,by shopping Trix and Märklins locomotive with the mfx decoder.
It´s not the locomotive,but instead mfx decoder which should be terminated for good.

Both mfx and DCC has been tested.
And no it´s not dirt on the track.
What another digital system?
I do have Märklin BR64 and it´s working without problem.
So it´s not MS2.
It´s mfx decoder in the bayern locomotive which are kaput!
