Good Morning,

I am a total newbie but hope to share in this hobby with my three sons, the oldest of which is train mad.

My son inherited a wonderful Marklin train set from his Grandfather. We had set up a basic oval track to test some of the trains. I plugged a 110V transformer (Model 6114) directly into the default 230V power supply. There was a loud hum and then then the unit turned off. I quickly realised what I had done and turned the power off at wall.

Have I destroyed the unit and is there any way I could try and repair (i.e. is there an internal fuse that could be replaced). I would hate to think I have broken something right off the bat.

I have now ordered a power set down transformer (240V-110V). Fortunately, there was another transformer to use and I'm not going to make same mistake.

Any advice appreciated - looking forward to this journey and getting lots of tips from this message board.

Anybdy starting a model rail layout should in my view buy new Marklin power pack and a control. This should come first and will last for years. Model rail and Marklin is an expensive hobby but itis important to get the basics right which will in the main stop future problems. Track is also important and C track will give good running. I understand why sets inherited have a family value from the past but might not be what a future generation is looking to use. A start set with an uptodate MS is a good way to start.
When starting I would call at a dealers shop or use a well known on line dealer. Ebay is not great if you are not familiar with the seller or what you need.
It depends on how serious the OP is on proceeding with the hobby.

Hello,

In my humble opinion, any person that has to ask in a forum if he/she has damaged a transformator, is not able to repair a transformator.
So, please : forget the lines of @marklinist5999 ! Do not open a transformator box if you do not surely know what to do with it!

You might find an electrician who is able and habilitated to open, to repair - and to certify that the reparated transformator is not dangerous.

Second opinion :

do not stumble with interposed transformators (240V-110V). Buy a transformator made for your electric system.
This is said for adult persons, I say it twice and more even for children. Children must be protected of misuse (accidental and "explorating" misuse) since electric shock is mortally dangerous.


On the other hand :



No, it is not.
Why?
This family wants to run the inherited trains. Have you ever tried to control analogical trains with a MS2? (MS was, by the way, the original name of MS1, obsolete since many years)
And if YOU like digital command, it is not said that children will really prefer it.
Mine have very different opinions on this:
one is fine with it, "no isolations to do between circuits".
one is indifferent, "I want to see trains rolling, and nothing to do for me."
one is really analogicalist: "I hate sound effects, and I prefer the trains rolling and not stumbling on every micro-interruption of alimentation."

If, if ever they want to go further, then it's time to think about "how". But for just testing and beginning, and enjoying the inherited material, they should not buy expensive rails that maybe they will never really need.
