I have bought a starter set for a gift:
Marklin "Era III Freight Service" Digital Starter Set. 230 Volts (29721) and also separately ordered:
1 20997 Märklin Märklin Start up - Entkupplungsgleis
2 72752 Märklin Weichenstellpult für
3 74492 Märklin Weichenantrieb C-Gleis
I just wanted to arrange electric turnouts and uncoupling. Everything was received but after reading more i understood that there should be also some transformer or something like this to make this stuff working. So now i do not know what to do :)
Could you please help me are these SET and items ordered enough to ensure electric turnouts and uncoulping? Or i need to order something more?
It should be very easy but it is hard to understand :)
Thank you in advance!
Serge
Hello Serge,
sorry, no stupid questions, only the standard Maerklin confusion. Sometimes I still get confused by Maerklin's business strategy, which is not easy to understand.
Indeed, you must have been confused by the articles you bought.
First of all you have to be aware that Maerklin has 3 major lines.
1. my world - forget it quickly again, it is only for the younger kids and can only be operated with batteries and not with regular AC.
2. start-up system - that is for the younger people to start and get used to high prices.
3. Maerklin standard classic H0, called now by Maerklin "Maerklin digital", because Maerklin renamed his digital standard world several times. This confuses, if you read something about digital of prior years.
You bought a starter package from “Maerklin digital”. But the other articles you bought in addition are from the Maerklin “start-up system”.
Both are digital and you can use both and you did not waste money. The only point is: which article fits to which system and how do they have to be connected. There are big differences, as you realized already by yourself.
The 2 major differences between "Maerklin start-up system" and "Maerklin digital system" is
first – of course - the price
and
second, the decoders and controllers, which has a massive influence of using your MRR. For the start-up system you have always to use cables. With “Maerklin digital” you can use one of the biggest advantages of the digital system. Built up and use a MRR without any cabling. This you achieve with built in decoders in the turnouts, etc.
As you see in the start-up catalogue, mostly a small box without any cables is shown as a controller. Whereas in your starter package you got a MS 2 with a track box. Only the high class start-up starter packages does also include a MS 2 controller. This shows you, that both systems are compatible.
There you bought additional articles from the start-up system, use it and include it into your standard digital system. @clapcott set in his post #4 a very helpful link to the start-up catalogue and referred to page # 64. So connect your turnouts and coupler as shown on page # 64 and explained in other posts, then it will run.
When it runs, come back and get more information about the differences between the start-up and digital system with their different world of decoders in locomotives, coaches, tracks, signals, etc. This is another world, but very interesting, fascinating and challenging.
