Afterwards .. I had technical difficulty in logging in. So, to continue, I am repeating my question and will explain why I am asking. To learn first hand, the relative advantages/disadvantages of DC and Marklin AC, I created one oval (circuit, course) of each. They are of course, completely separate from each other. In my HO KATO track DC with 3 pairs of turnouts (points) for 3 platforms, the KATO turnouts are power-routing, and so I can choose to run any one of the three trains at a time while the other two stand still. But in my separate Marklin K track oval with a pair of turnouts for two platforms, no matter which way I set the points (turnouts), both trains will run! So, how can I make my Marklin K-track turnouts power-routing so that only one of the lines will run?

Due to the symmetric Märklin system, there is no problem doing so, no trouble with turnout frogs. You can insert centre-rail insulators at both sides of the sidings. Then use a switch box or relay to turn power on or off as needed. Or operate locos digitally and have power on all sidings.

Then use a switch box or relay to turn power on or off as needed. In addition to what Tom (H0) wrote, historically Marklin used signals to turn the power off once the centre studs are isolated. The signals have two switches in them, one for switching the centre rail, and one for switching the overhead when running electric locomotives powered through pantographs.

In the 3 rail Märklin culture, things are very different: - trains can run into switches not made for them without any inconvenience (short circuit , etc) - trains can run on independent directions on the very same track (because of the internal direction relay or decoder) - you may have ANY circuit figure w/o any issue (reversing loop, reversing triangle switch, etc). - when using, the historic M track, any paper will allow to create an isulated section (for signal stop) - some special contact tracks give you a different impulse depending on the direction. So, with all this fun, the price to pay is, there is no power-routing swiches (but you can make one using a relay or a larger Reed contact (depending on the type of track you are using (C, M, K) Cheers Jean

Need to a) buy centre-rail isolaters, one pair, b) and see what the relay is, whether I alreay have one or ust get one, c) I have a spare trafo which I could hook up to the isolated track .. this means that when I want to run the 2nd train on the isolated section, must turn the second trafo on. Easy enough. Thank you for the prompt replies.

Easy enough. Thank you for the prompt replies. There is a 'gotcha' to using more than one transformer, I'm not sure of the signal Manual I pointed you at above contains the details, but the Maerklin Miniature Railway Handbook certainly does. I thought we had a copy linked from the forum, or uploaded by someone, but it is not linked from https://www.marklin-users.net/fo...ns---requested-documents [edit] The Marklin Miniature Railway Handbook can be downloaded from here. You will find a lot of essential information about how the items you have work in it. [/edit]
