Restore the startconfig backup to reset it to delivery condition. You can also restore the "Leer" (empty) to reset it to completely empty.

I am struggling to get the new CS3 to do anything. Been trying to get it to recognise 1 mfx Loco but the Stop will not release so I can't get it to operate a loco. I have rebuilt the track layout so that it's reasonably small but at least all tracks are connected properly. But I still get the Stop function locked. I am going insane here!!
I have 2 Mobile Stations and I had no trouble with them however as soon as I had coaches with lights on the MS3 would overload. So I borrowed the money to upgrade to a Central Station 3 but........as I say I can't even get a loco recognised and running. I did think I made a few errors in the set up including accidentally hitting the restore button BUT instead of a factory reset (which is what I expected) it took me to a pre stored list of 4 locos (I think....) 3 of which I don't have and the new 37797 TGV set which it recognised but would not get it to run. It's not as if I am computer illiterate as I have a MSc in Computer Science.
When I rang Marklin Customer Service in Germany the (very) limited advice served no purpose whatsoever in the 3 minutes I was allowed to talk to the Marklin expert. I despair at the lack of any technical support on items that have cost me £3,000. So in desperation I am using this forum in the hope that some kind person will help me get this expensive kit to work.
Fingers crossed, SavoiePaul

No offense, but you caught the thread of @twisterdodger. May you please open your own thread? It is not possible to answer two different askers in one topic. But before try a bootloader update. You find it under system/settings and you can go there even your red STOP bar is lightning. But you have to tickmark the button bootloader update first. See page 32 of the manual of the CS 3 about basic settings of the CS 3. If an update is broken, which can happen, nothing is working any longer.

Hello Alan, I am using a new 60061 power unit, Paul

Thank you so much for your detailed reply, it is much appreciated by me! I have tried following your advice but still no luck. I clicked on the Restore button then deleted the loco list (2 not mine) then did another Restore and got it back to original factory settings (I know because when I did the reboot I had to choose language again. This time I didn't do an update and placed a new M 37916 on the track.....but the Stop will not switch off so it will not register the brand new loco. I then removed the CS3 connection and attached my MS3 and it quickly read the mfx details and away it went. Why will the Stop function not switch off, well that's the £3000 question. I am going to try again tomorrow but this time I am going to connect the CS3 to my network via an ethernet cable (my layout is in my garage). I will do an update when CS3 is on the network and see what I can do. I want to give you a HUGE thank you because I always blame myself if anything digital doesn't work for me! It's time for a glass of wine now. I will report back to you tomorrow. Oh by the way have you heard of a CS3 app called Remote CS3? I found it in google play store. I can't test it until I get my CS3 ethernet cable in the morning. I am not optimistic about the app because I bought the the Mobile Station one which is useless if you only have the MS3. Grrrrr. That reminds me, if I were to plug one of my MS3 units into my CS3 could I then use the MS3 to drive the loco? Just a thought. Must get my glass now, very best regards, Paul


Well yes you confused me, because I regularly do not look on the date of a thread. So I did not realize first the time difference in this thread.

Anyway, did your new CS 3 was working one time since you got it?

I also do have 2 MS 2 with a track box. Then I bought a CS 3+. This was a tremendous step, because used to a MS 2, I had to learn - no to study the CS 3 till today. But I always had and have the possibility, if something is not working well with the CS 3, testing it by the MS 2 with the track box first. This excludes any male function of my layout, when it works by the track box but not by the CS 3.

Then I tested it with a MS 2 connected via the CS 3+ to the layout. Achieving the same results as with the track box, I always know the GFP (Gleisformatprozessor = track format processor - it is the processor creating the digital signals for the layout) in the CS 3 is working too and the layout gets current.
(BTW the track box has a GFP included as well, not the MS 2. This is the great difference to the MS 1).
If this all is working, but the locos are still not running, I realized my unsatisfactory or unknown handling of the software of the CS 3. But for this you do not need a reset for the total CS 3. A partial reset is sufficient. Otherwise you delete to much other individually, personally setted valuable structure in the CS 3. Think at the track plans with all the solenoid articles in there. At a reset all this is gone as well.

In your case I assume that in your system settings something has gone wrong. First I would try the already mentioned bootloader update. Which software version do you have on your CS 3?

After booting a CS 3 you go to system-settings/system(yes this is confusing - me did it too) and not system/network! Then choose CS 3 (and ignore the assistant for this time) and see the menus starting with "shutdown" "restart" etc. Scrolling down you see the bootloader update button, scrolling further down to info, Open it and you see your software version and more information of your CS 3. Mine has the newest version 1.4.1. You shall have this version as well.

The GFP3-1 version is 12.62. You find this under the menue point "TFP3".

Try the bootloader update, but follow the instructions as written in the help section in the CS 3 (the text behind the question mark “?” button). E.g. it is important how you shut down the CS 3 after you have done the update. The various available closing procedures of the CS 3 close various apps in different ways and this has an effect on the software installation. It is like in Windows.

Then inform us about your results, please.

Hello again TEEwolf, I got the factory reset in the CS3 I then put my ethernet cable into CS3, it then prompted me to reboot after update had finished. It is version 1.4. I still get the Stop function stuck on.....So I know the update was done correctly. I am now thinking that the wiring is not right. I know I put the RED wire to the shorter rail connection and the BROWN on the longer one.

I know I put the RED wire to the shorter rail connection and the BROWN on the longer one. How do you do your connection? Do you use solder? Or squeeze the clip with tweezers so that they can't slip off? I have used duct tape to stick the wiring to the back of the track but that doesn't work. Any ideas would be of help! Very best regards, Paul ps you are right that it takes time to get these things to work. I recall it took me about 5-6 days to get to grips with the MS3......

I use pliers to squeeze the female wire connectors onto the male track connections. They are almost always too loose or too tight. Sad that Marklin no longer makes a c track with plug in connections to avoid all that

And please DO NOT START ANOTHER THREAD ABOUT THE SAME PROBLEM. We do not need it, and it only makes it harder to give advice.

Moderators, can we merge this into the other thread please.
