Does it start if it is not connected to the tracks?
I ask this in case there is a shortcircuit somewhere on the tracks.

Good day, dear Members of the forum.
I want to report a how ended my story with the repair of the Central Station 2 (station doesn't boot).
I hope my positive experience will help You make the right decision and save time on solving the problem with Your Marklin-equipment.
Highlights and details...
On the 14th of December 2014 I wrote a letter on official address of the Maerklin-service (an address I got from the site maerklin.de).
After a week without a response from Maerklin-service, I sent another letter from another mail server (gmail.com).
In parallel with these events, I attempted to contact representatives of Marklin in Russia. Since I made the purchase on ebay local representatives said that they would not be able to help me (and the issue of cost was not even discussed).
Also I started looking for a way to solve the problem on the forums: and in Russia and in this forum. To my regret, I came to the conclusion that there is only one possible solution - repair is possible only in Germany.
And on the 30th of January I received a response from the service center Marklin with possible options to solve the problem:
- will go to the local representatives of the company Marklin in Russia
- to send the item for repair in one of the service centers, including in Goppingen.
I wrote a lookup about the required documents for the repair and cost of repair.
2 January 2015-the year I was told about the required documents, which confirm the date and place of purchase and confirmed the warranty (cost free if warranty seal are able).
The 3rd of January I sent a parcel (from Moscow-region) to Germany and the 9th of January it was received in the service center.
29th January I sent a letter with a request to clarify the status of the repair and the 4th of February, I received a reply with incoming registration number for my request on repair.
On March 10, I decided to clarify the status of the repair and 12th of March I received the reply that the repair is completed and my station is ready for sending. I noticed that in the document which was sent to me from the service, my address is written with a small error and hastened to clarify my address again.
18th March 2015 I decided to check the shipment status and has requested a postal tracking number. The next day I got answer from Service with the tracking number from which it followed that my station was sent on 25 February and now the parcel is already in Russia and most likely at our local post office. March 20th I went to the local post office, where i found my parcel. A receipt of my parcel the postman could not deliver to my post-box, because the address was written with a small error - without number of my flat - just as it was written in the documents service center :-)
As a result:
- for all emails (with a few exceptions), which I sent to the service center, I got answers from Service;
- all my requests for repair were fulfilled (there was a separate requests: for replacing the buttons with the incorrect picture + updated software);
- the repair was carried cost free.

I am sincerely grateful to everyone who responded to my problem and to all the staff of the service center Maerklin in Goeppingen.

In turn then plan to add to my collection novelties from catalog of Maerklin 2015.
Particularly attracted to the models "Orient-Express", BR18.5 and "Lessing"
