Hi to everybody:

I am new on this forum and perhaps this topic already have been discussed.
Actually I am preparing my H0 digital layout with a mobile station 2 and C tracks; I have a lot of M tracks of my "ancient" layout and I would like to use them. As far as I have read, I should buy 2 M to C track converter (Ma 24951)...Is this all I need? and work this properly?

Thanks for your answers or advices.

I have 4 of them and they do not give me any problems.
A piece of advice though, as there is a slight grade change AND the track profile is also changing, I would not recommend having an M track curved piece attached to this or a R1 or R2 C track curve attached either.

If you must have this and some cars or loks give you grief, just pay attention to the track geometry or wheel spacing. 90% of the time, this track will give you no problem.

You may want to use the M tracks for "inside" portions, like parking areas rather than on the main running part. I say this because you may find that the M tracks are more noisy than the C tracks and rougher where they join. In other words, more modern and lighter digital locos may jump a bit when going over M tracks.

I used to dislike C tracks since they are made of plastic, but the trains run very nicely over them, with no jumps and much less noise.

As for joining the two, I also think it's best to join them only with straight tracks. The connectors work well but feel a bit delicate.

Hi!
Welcome to the forum.

With respect to all track, especially M and K track: remove all radio interference suppressors (capacitors with M track and K track) when you go digital.

If you have feeder tracks with capacitor, don't use that tracks or remove the capacitor.

Tom

Hi Carlos,

The tracks themselves are the easy part. Just buy as many adapter tracks as you need and follow the advice you have received and you will be fine. One thing that I have struggled a bit with is that there only exist straight, normal length adapter tracks.
The big question will probably be how you intend to operate your old turnouts that I assume that you have.

The analog way is fairly straightforward. It is when you start thinking of doing it digitally that you get a lot of options and opinions. As you can see from my previous post I have almost finished that project. Not totally smooth sailing, I must say, but it can be done. I got a lot of inspiration and insight from Martin T at http://märklintåg.se/index_e.html

So thank you Martin. I am not sure if I would have done it without your site that inspired me to do further research. And I'm glad I did it. BigGrin

But maybe you have figured out that part already?

Lars

I still don't understand why the C to M Track converter actually goes from C to K track profile, meaning that the rails go from K to M track profile where the C and M Track connect.
Maerklin should have kept the C profile on the entire length of the track, as the rail profile is much closer to M than is the K design used.

Sorry, Mike, but what are you saying? What do you mean by "profile"? Confused Confused

Profile refers to the shape of the rail. Märklin C track is stainless steel, 2.3 mm high. K track today is stainless steel, 2.5 mm high. Old K track was like M track with rails folded from tin-plate, about 2.5 mm high.
The head of the K track rails is flat and wide, while the folded head of M track is round. The head of C track is much narrower than that of K track.

With the transition from C track to M track you start with narrow C track rail tracks, get a few centimetres of wide K track rails before the rounded M track rails come.

They had to make the transition from 2.3 mm to 2.5 mm. Instead of making new 2.5 mm C track rails they used the existing 2.5 mm K track rails.

Thanks for that explanation.
