I find the 2018 Märklin TGV quite interesting and I am hoping to tap into the wealth of knowledge on this forum concerning the desirability of recent TGV models from Märklin. I have considered some of the earlier editions of the TGV but I could never quite pull the trigger. However this world record run edition is very interesting to me and I am considering a pre-order of it.

How well do the earlier editions operate and how nice do they look? If they do a good job with this livery it might be quite interesting although they have yet to make even a hand sample of this train, so that part is hard to judge. I have never actually seen a Märklin TGV so it is difficult for me to anticipate how this model may turn out.

I have already seen one online dealer listing this train as sold out at the factory, so it might need to be ordered sight unseen, which concerns me. But if the earlier editions were nice enough it might be worth taking that chance. I saw the Märklin production manager on Märklin TV saying that they see this model as a significant challenge which they are eager to tackle. Were the previous TGVs convincing enough that we can expect this one to be a winner?

Thanks in advance for any information that anyone might be able to supply on this subject.
Regards,
Jim

I have almost all Märklin and mostly HO, although I do have a small number of Z gauge trains!
So many trains and so little time.

The biggest problem is the wheels. They come off if you run it fast through bends - although I did has them come off in a straight section too.. I have the Thalys and the TinTin Thalys. If you run it slowly as if it is leaving Gare du Nord station then it works fine.

The other problem is that it is very light (possibly something to do with the wheels too), but then it can't be heavy if you have all of the extra wagons in the trainset as the motors would not be able to take the load..

To be fair, the problem may be fixed with this new model. As you say, sight unseen has risks.

Hello Jim,

Yes a very tempting model and yes it seems to be sold out already. I own the Marklin 37794 THALYS and I really like it and would recommend the set.

Regards.

I've preordered it.

I have 37796 already with all the add-on cars. It works great but the speed is limited. Its not as fast as my ICE3 37780.

The wheels have a plastic part under them so the wheels don't fall off. That's the first thing I noticed because i got a plastic part that would help coupling the train. It doesn't work due to the new plastic part for the wheels.

I believe there is a fix for this, but I have no details on it.

Wow - first off I would like to thank everyone for the quick and helpful replies to my query! This forum rocks.

I am not a rivet counter by any means, but the wheels coming off seems to be a pretty significant issue to me. Since you have ordered the 37797 David, perhaps the 37796 represent a fix for that problem. I can deal with the maximum speed I guess although it is odd for the world's fastest train set to not run very quickly. With a short consist, plastic coach bodies and two powered units I was not expecting that to be a problem. You would never expand this particular set though so maybe that is not true for this model. The old sight unseen bugaboo indeed Adrian!

My dealer still says that I can still pre-order this train but since it is factory sold out I will need to act quickly. I guess I am still on the fence, as I have been on the previous editions of the TGV.

Thanks again everyone. Decisions, decisions.
Regards,
Jim

Here's a picture of the 43426 for the 37796. And you can see Märklin has added a small frame thus preventing the wheels to fall off.

Cool. Thanks for that image David!

It makes me feel better knowing that Märklin has addressed that problem and I am sure that the TGV will be amazing in the record run livery. I guess that explains why they are selling out so quickly.

I stopped collecting Märklin for a pretty long time and I just returned two years ago to the world of only online dealers and me finally having enough money to get what I want. Cool

This whole "buy it quick of never get the chance" thing is tricky for the buyer, although I am sure that it is helping Märklin's bottom line. Unlike some I am OK with that though because I very much want to see Märklin survive in this tough market for toy trains.

I am giving myself a couple more days to decide for sure, but I am leaning more toward ordering it now. BigGrin

The most important thing to remember is just because an item is factory sold out, it does NOT mean that all of them are sold. It means that the production has been ordered by the various distributors and dealers and many of them will still have quantities in stock. For example, French dealers might have ordered 60 for pre-orders, but the French distributor might be sitting on another 60. The same would be the case for Switzerland and Austria.
And just in case that you can't find one at the dealer of your choice, there are always the big online sellers and ebay.

Hello David,

Thanks for the picture. I will look at the 37796 exploded view to see if I can get the part number for the clips or the bogies.. My dealer stopped ordering them after the problems with the 37791 (2011) and 37795 (2014) the two models I own.. I was so desperate for a Thalys I broke my golden rule - never buy the first of a new model. With the Tin Tin, I incorrectly assumed that they fixed the problem after three years.. Blushing

NP Adrian. Very strange indeed that Märklin hasn't let their costumers know about this problem. I bought the 37796 after seeing the special function work the wipers.
I was concerned about the reports of the wheels falling off but after receiving the middle cars I noticed no problems.

That is true Mike. I know of two online dealers who will still let me pre-order this TGV right now. Factory sold out means that dealers have bought all of the 3,000 that Märklin will make but not that the dealers have sold all of theirs yet.

In my experience though it also means that they might also sell out from the dealers soon as well. On the other hand I still know of a dealer who has a Goliath crane car, which was factory sold out a very long time ago and it is now available at a significant discount.

Jim

Hi, I have the first TGV and Thalys. In addition, I have the TinTin and the TGV Lyria. I have used those a lot and never had a problem with the wheels. This for your information.

Good evening all,

Please find attached some pictures of my brand new model. I will look at it everyday as I will display it on my desk at work (I am an SNCF Engineer).

I’ve also made 3 videos on YouTube. Just look for Marklin 37797.

It works great. Slight disappointment as the top speed seems a little low.

Any questions, just shoot.

Cheers.

Antoine

Thanks so much Antoine!

I will be waiting for mine for a while yet and it is so good to see some images of the actual product from Märklin. I think that the prototype is quite possibly the most beautiful train that I have ever seen! BigGrin

The slow top speed was kind of expected because the earlier editions of the same hardware were all dinged for that too. You would hope that for the world record holder you might fix that error. I guess it is just one of those Märklin things, like the wheels falling off and them stalling on curves. I am hoping for the best and this is one train pretty enough to keep even if it does not run properly. Cool

Thanks Again!

Regards,
Jim

As do I David! BigGrin

But if you really want one of your very own, time is getting short.

It really is a quite beautiful train and it would enhance any layout IMO. Cool

Hi guys
I got the 37797 yesterday and begin to play with it .Have several questions
1) what is the best way to disengage the set to the 3 part like it come original 2 *(loc+wagon)+ wagon ?
2) does I need to attach all the set so it will work or can I attach only part of it (loc+wagon + middle wagon) ?
3) does any one use it with ecos command station and if yes does it work smoothly ( I read the data from the 39970 and for some reason and don't know exactly what happen
after some time it stop working ( did not preform functions or drive command )

I have only had my 37797 for about 10 days so I have not yet attempted to separate the units, but I am fairly certain that you just pull them apart. At least that is what you do with other similar Märklin connectors. To me this always feels wrong but that is how it is usually done. As you already know they gave us instructions for putting them together but say nothing about taking them apart. That is another reason why I think that you simply pull on them until they separate.

Because of the nature of the wiring and the dual sliders it will not work properly unless it is completely assembled into the whole train. At least that is the case for my other trains with a slider on each end.

Can't help with the ECoS, since I use a CS2 to control my trains. Hopefully some ESU users will help with that one. Have you tried to register it again?

1.you can't disconnect the transition cars at all.
2. Yes. But you can only drive in one direction. If you change direction the train will need the rear part of the train to get power.
3. I don't know.

Good point David. That is something I assumed Doron understands, but it is well worth emphasizing.

Right - and once you change direction you are stuck until you assemble the whole train again. If you don't reverse the direction though I guess a partially assembled train might fit on a rolling test stand for testing purposes.

I have almost all Märklin and mostly HO, although I do have a small number of Z gauge trains!
So many trains and so little time.

Any thoughts about the quality of this model?

I received mine a couple of weeks ago, and generally it’s a quite nice model. But a few things could be better.
Details is fine, print is good. And the wagon light is nice. I find the max speed is sufficient (after CV max speed set to max).

I find that the upper plastic body has a bit thin and fragile filing, and I don’t like the clip on fastening without screws. The body was also glue to the frame, in the aft. It’s easy to chip of some paint when bending out the body, to open it.

And after a small derailment, I had one disconnected joint on the drive shaft, connecting the motor and drive shafts. When I opened the other end I also discovered one shaft that was not properly connected.

Other observations, is that the pantograph end is where the decoder and speaker is located, there is also a 220uF 50v capacitor. Decoder was delivered with firmware 3.2.0.1, and is upgradeable. The mDecoderTool3 and usb stick can not change any settings.

Some pictures from inside the TGV :

I agree with all of that. The graphics, finishes and performance are all excellent as I would expect from Märklin today. The lighting is quite well done and it looks a lot nicer than some other Märklin TGVs that I have seen.

Opening them looked ugly and I decided to just skip that for now. All of my recent Märklin locos have come well lubricated from the factory and I will only have a few weeks to run that train anyway, so I put that off. Now I will look forward even less to taking that apart, which may be sooner than I thought.

OK - so I guess I really do need to open these up and inspect them. The front power unit is sort of noisy and now I wonder if there are drive shaft issues there. I will put it on my list.

I was not aware of a capacitor but the performance is perfect and that makes sense. I have been having some good experiences upgrading older models with third gen Märklin decoders and the mDecocerTool3, so I am a fan of the current tech. But I am a techie myself and that is stupid on Märklin's part to lock these otherwise quite capable decoders down. The majority of buyers would never try to change the CVs anyway and people who know what they are doing are just irritated by the pointless need to buy a new 21 pin decoder. Bad choice Märklin.

1) what is the best way to disengage the set to the 3 part like it come original 2 *(loc+wagon)+ wagon ?
2) does I need to attach all the set so it will work or can I attach only part of it (loc+wagon + middle wagon) ?
3) does any one use it with ecos command station and if yes does it work smoothly ( I read the data from the 39970 and for some reason and don't know exactly what happen
after some time it stop working ( did not preform functions or drive command )
Regards Doron


1.you can't disconnect the transition cars at all.
2. Yes. But you can only drive in one direction. If you change direction the train will need the rear part of the train to get power.
3. I don't know.



I have the first TGV edition from Marklin, the 37790. All the other versions of this model (exclusive the World Record), share (almost) the same parts, even though they have different part numbers.
The 37797 also has also 2 motors. If they are connected in serial, like all the other TGV versions from Marklin, you won't be able to drive the train if it doesn't have the two end units connected.
But depending on which direction the power pick up change relay was set before disconnecting cars, you could be able to control the sound and light on the decoder unit part.

I agree totally with you here, it’s very annoying that the decoders are locked down. Does anyone know how to unlock a Märklin decoder?

Something that should work is to reflash it with the same firmware that comes on mSD/3 decoders, although that might be hard to come by. That is easier in some environments and with some chip than others. But you can reflash pretty much any chip if you have a valid image to put in its place and the right tools. There might be other, less drastic approaches but I have not yet heard of any.

I would think that it depends on just how badly you want or need to make changes and if you are willing to buy a new decoder to replace the one that Märklin "broke" at the factory. This is a model of a unique prototype and I guess they might want them to remain as they were designed. As a software guy I don't like that but it is their company and it does make sense on some levels.

I am just glad that mine runs so well and am not really motivated to change anything beyond the CVs that are open right now anyway. I find the speed quite acceptable BTW which I did not expect, and so far I am very happy with this train.

Jim

Maybe someone can help I just
Got the limited edition cs3 picked it up instantly all the sounds and lights works but it wont move at all what can I check for.
Other trains run on the track in-front and behind.
Really desperate to play with it it is brand new never been opened

Hi
Does the TGV give any motor sounds at all ?(from the physical motor's not sound effects).

If not, you have to check for poor contacts. Check connections between the wagons and that they are properly coneccted etc.

If they do give some sound, you have to open the drive ends and check for disconnected joints on the drive shafts.

it could also be a combination of the above. don't have schematics for it so I cant tell how it's wired up.

The decoder could also be damaged.

There is a clicking sound when you change directions.
If not, you have to check for poor contacts. Check connections between the wagons and that they are properly coneccted etc.
I have not opened the cars but the lights inside all of them work and in each powered car.

If they do give some sound, you have to open the drive ends and check for disconnected joints on the drive shafts.
Drive shafts are all connected did not check if there is power to the motors will have to ask someone to bring a multimeter to check for me what is the required power

it could also be a combination of the above. don't have schematics for it so I cant tell how it's wired up.

The decoder could also be damaged.

I hope it is not the decoder is the a way I can run it in analog to check if the motors work.

Thanks in advance for all the help sofar.

Do you hear any motor sound in digital ? (for analog testing you need an analog Transformer, and don't use it on an old blue one)

You could also try a decoder reset (at your own risk). but I strongly advise against trying a firmware update in your case.
