Any ideas, anybody?
My Marklin TGV is a little slow (max speed 190-200km/h) and the volume of the sound is low, even at 100%.

You can't produce or improve something, that has a lock.
Until Märklin unlocks its mfx protocol, you can forget about it.
Modelers who lock themselves into a system unfortunately have to put up with the consequences.

This is why I do not have a single mfx loco in my collection.

Hello,

this was claimed from a lot of people. It seems to be a design problem.

The new Thalys PKBA runs quite faster following the first feedbacks in the net.

send it in to Märklin requesting to improve maybe with Thalys driver.

This thread is yet another excuse for the Marklin bashers to have their say.

Both the maximum speed and the sound volume are fully adjustable using the MFX system. No amount of fiddling with arcane protocols will make it louder of faster if those settings are already on maximimum.

This is a design problem which Marklin have addressed in the later models. It has nothing to do with the MFX system being locked or otherwise.

I would follow Stephan's advice, and try to ask Marklin if they can do anything about it.

If the Thalys is faster than the TGV POS;

Logic says fitting drivetrain, pcb, decoder (and other electrical components) from the Thalys spare list part should give you a quicker TGV POS.
If you replace Marklin's OEM decoder with a reputable third party decoder, you'll probably end up with a better runner too.

This is not recommended to do on a new Marklin, however.
It will also be an expensive exercise... why would you want to spend so many hundreds of Euros for a new model, only to have to fix it again yourself?

But chances are Marklin won't 'fix' the TGV POS only so that it can match the speed of the Thalys.
(no guarantee on top speed!)

37790 is currently on yellow light -
this might mean that the second production batch will contain the "fix";
but then it may not...

You can ask Marklin, but their customer service probably won't know the answer.

Not a bad idea.

...Unless the problem is with the motor/gear combination. It could be that the only way they found that it could handle the full weight of the train with one motor was to gear it to run slower. If this is the case, changing the decoder might not help. It might need someone to actually try it and report back to the rest of us.

It's really a shame that marklin didn't issue a TGV which run at a correct speed

Windigipet has a process whereby all your locos are calibrated to produce speed curve... The two step option (there is a 14 step option, but I am too old to see out all the testing) tests for 70 km/hr and 140 km/hr by selecting middle and full throttle.. By coincidence, I was able to speed the weekend (between washing loads) in the train room calibrating my fleet of operational (there are now three deaths) digital and delta locos..

At full throttle, one of my plastic bodied non-markin locos derailed on the R2 curve at the scale speed of 197 km/hr during the 140 km/hr test.. Incidentally, the fastest loco of the day was not the ICE1 camera train, but a 3430 with a 60760 decoder and a five pole motor which topped 205 km/hr during the 140 km/hr test! The Flying Hamburger was much faster than the 26020 ICE1 and the 37770 Zeppelin! This goes to show that Marklin do not scale the performance of their locos to prototype.. And the C-sines were the best performers of the day in that they had the same speed forward and backward!

.....one thing I'm almost sure about is that it's not a matter of drivegear....1 or 2 retailers suggested that it may be the drivegear and then.....start a buzz on the internet ! ....probably because recently they were confronted to the Roco model of SBB Ram for which there was a real problem of gear ratio, it was so slow that Roco had to send new replacement gears to retailers ....

BTW : 320 km/h at 1:87 scale is about 1 meter per second.....that's really fast , to avoid accidents with other trains a special High Speed Line is recommended ....
