I don´t understand why people are still talkning about C-sinus motor?
Leave it!
Märklin does not take care of it anymore time.
DC motor rules now in Märklin Göppingen.

SDS was followed by Soft drive sinus, then compact sinus motor. M realized the compact was garbage. The plastic housing cracked apart. I realized change was inadvertant upon removing the body off my 39120 E 10 from 2007. It has the can SDS motor. It runs well. Some reported here having operating issues with speed control. Turns out the the sine waves interfere with MFX, and M wasn't trashcanning that. So away went the C sine. It was also a cost saving measure. My using the same type can motor as other makers, a 5 pole, like Mitsumi, etc. the cost is much less, and makes compatibility with dcc easier. While myself I've not had any running problems with my three C sine loc's, I havn't tried running them with other mfx devices in operation yet. I have ran my 39355 Taurus, and 39573 br 103 at the same time.
A 3900 series since has meant MFX+, until some recent issue 3700 series models also have mfx+ world of operation now.

C-Sine is sometimes called C-Swine.

Personally I never had any major issues with C-Sine based motors or their derivatives. I had some jerky running from a 39010 BR01 with SDS motor until I stopped using a 60052 transformer to power my CS1 and powered it with a proper switchmode power supply.

I have a c sine, it’s very smooth 👍and runs at a consistent set speed 👍

My experience with SDS was and is good Never had problems except with 39010: it stopped running and Märklin replaced it under warranty.

Here is 3937 locomotive.

well, there is a French movie called Amazing Amelie, haven't seen it.
I find that the locomotive and model are nicely done.

If you are also referring to the Bonfire locomotive, I believe that it was owned by EWL GmbH East West Logistics at the time, and rented out to SVG - Stauden-Verkehrs-GmbH
The metal band Bonfire made several music videos where the locomotive used.

I would like that as well. I would really like another set of UP coaches to make it a more realistic consist than just four coaches and two baggage wagons being pulled by one of the largest steamers ever built!

I agree that an end car would be nice but my UP streamliner book says that UP only bought a few observation cars with blind ends, and those were later converted to a normal configuration to make train assembly easier.

A SP cab forward would be one of those must buy offerings for me, but unfortunately I really don't expect to ever see that from Märklin. It would also be nice to see some passenger coaches which were not Budd coaches, but that seems pretty unlikely as well.

Hello Jim. As a long time Marklin operator since the 60s I wonder what the % is of how many Marklin people in the USA buy U.S. prototypes? I have never bought any

as I've always loved European models/prototypes. The company must do research on this I'm sure? Just a thought. Cheers! Peter.

Dint not why it's not listed on all, but as far as I know, they do have it. and e.g. 39068 have it listed.

The dynamic smoke is nicely demonstrated in this review:

I recently acquired the Lineas class 66 #39062. A nice looking loco but the smoke has not convinced me. Not that it was too few smoke, on the contrary it is too much. I just let my loco run for 10 minutes with smoke, and then I had to evacuate the train room because of the smell and smoke. Even with the window open all night, I could still smell it the next day. So I won't be using this feature a lot in the future.

If only it had the piezo element with plain water, that would not have been as bad for your health (but bad for rusting crail pukos though). I want to save my lungcapacity for when I eventually catch the coronabug, which will probably happen sooner or later.

Maybe they should have copied the curve sensor and braking spark feature from ESU instead.

Yes, it's a nice model, and I'm quite happy with my CD 66 (39063). I do like the "extra" long-distance lights as well, thas are unique for the CD 66 and the new T66 (39068). I'm curious to see if Marklin also changes the snowplow on the T66 as they did with the CD 66. the "crippled" snowplow is the only minor downside. (i plan to modify at least one of the extra showcase plows included, so it works with a nem coupler.)

As for the smoke generator, it works fairly nice and does a reasonable job to mimic extra exhaust during acceleration. we will just have to wait for someone to develop some black smoke fluid.
the smoke generator part number in the paper manual, included with the locomotive, is the same as all the part numbers listed on the webpages. I don't think that it smokes that much, as a couple of Br53 also smoke a bit. But it seems to me that the ESU smoke oil is a bit more smelly than the marklin oil, haven't really compared them side by side, so I might be wrong.
