Hi all


The instruction manuals for these locomotives (37475 and 37477) state that the decoder address can only be changed at the factory. Does anyone know why? Are the decoder's dip switches not accessible, even after removing the shell? Has anyone succeeded in changing the address of these locos? If so, how did you go about it?

Thank you!
Best regards,
Armando García

Hi Armando.

I have 37476, and I opened it up once to see if it was possible to change the address, but I couldn't see anything obvious. There is a potentiometer for setting the acceleration /breaking delay, but that's about it. It must be a solder job, if it is possible to do it at the factory, but I couldn't see where to make the change.

Hi!

DIP switches? Which DIP switches?

There are 4 solder pads. Using a solder iron, you can easily access all Delta addresses.
All 80 addresses are possible, but require adding cables. I daren't do that.

I heard from folks who made it - and I heard from one who grilled his decoder in attempting to change the address to 69.

Try address 6 for starters. You only have to close a single solder bridge.

BTW: E 69 02 is "Pauline" and E 69 03 is "Hermine".

Hi

Given that the locomotive numbers are 37xxx, I automatically assumed that there might be dip switches on the decoder, like on every other 37xxx model.

According to your explanation above, changing the factory preset decoder address involves complicated soldering work.

If the addresses are not changed, would it still be possible to run two of these locomotives in "tandem" mode by means of the CS2?

Thanks for the clarification on the nickname of the locos.
Best regards,
Armando García

If you restrict yourself to Delta addresses, it's a very simple soldering work: two pads with a small gap inbetween must be connected with a small amount of solder.
It's easy. I did it twice.

If you use e. g. 6 or 18, you don't have to open the existing solder bridge (for default address 24).

The addresses of first generation Delta decoders had to be changed that way.

Changing to non-Delta addresses is difficult. I daren't do it.

Double traction: register one loco in the controller (any controller), put 'em both on the track and they'll both run.

Pauline is equipped with the decoder containing the solder pads. I left it on the factory preset address 24. No problem at all since my Hermine came already factory equipped with the programmable decoder, like it is installed also in the successive models, for example #37478 (I changed its address to 25).


Thanks, Lutz. Do you mean that the 37477 already comes with a factory-equipped programmable decoder where you can change the address WITHOUT having to solder anything? Could you please confirm this? That was not the case for its predecessor, 37475, despite the 37xxx numbering. The only reference that I could find on the Märklin website was: "Mit Digital-Decoder und geregeltem Miniaturmotor". However, AFAIK, this doesn't mean that you indeed can change the address, does it?

Armando, please note that not all 37477 came with a programmable decoder ex works.

According to the spare part list, 37475 and 37477 have the same decoder.

If your 37477 came without potis on the decoder (adjustable max. speed and delay) then you have a programmable decoder.

Tom

Thanks. The fact of the matter is that I only have the 37475. I'd like to purchase a 37477. However, I'd like to make sure that I can change the decoder address without having to incur in greater costs. I'm not able to perform electronic soldering work, and sending it to a dealer or the factory to have it done would mean $$$$.

My understanding is that the only possibility to have both locos (37475 and 37477) would be in "tandem" operation, as they would only be controllable at the same time. Have you tried this yourself with these two locos?

(Beam me up, Scotty!)

Either ask the seller to verify it has a programmable decoder (by looking at the instruction leaflet (programming instructions) or the decoder (no potis)) or do it yourself (soldering for behinners).

I'm afraid I never tried tandem operation.

I can post pictures of my decoders (if you like), but that'll take a few days.

Scott me up, beamy. It takes leather balls to play rugby. Ken sent me. (Anyone remembers that game?)

Hi,

I take this opportunity to ask if somebody can clarify the tandem operation.

My understanding is that tandem operation is possible only if both locos have exactly the same speed for every speed number, and more, the same Acceleration/deceleration delay. And probably needs for one loco to have the load regulation in OFF state.
And this only possible if at least one loco has an adjustable speed table, which is not (generally) the case with Marklin decoders.

May be the case of E69 is not so critical, for they have only 1 traction tyre, and the wheels can skid if necessary?

Thanks,

Fred

Hi Fred,
The instruction manual for the CS2 says that both locomotives need "to be similar in their running characteristics". I suppose this means that they must have the same type of motor and decoder, like two crocodiles, for example. The function "multi-unit operation" on the CS2 may be able to regulate the operation of the two or more locomotives thus interconnected. Unfortunately, I haven't tried it myself yet. So, comments from other members will be highly appreciated. In the case of these two E 69, maybe the fact that they have the same decoder address won't really matter after all in tandem operation via the CS2, but again I'm not sure.

Best regards,
Armando García
