Is this correct ? Does anyone have pictures of a c-track layout using R9 (if they exists) or a link to a website where they can be seen ? Thx in advange BR Steen

You could know all this if you would have a Märklin catalogue, which you should have if you are a real Märklin fan! You could also have a look at the Märklin site, http://www.maerklin.de/produkte/

But as Nico points out, R9 is only available in 12.1 degree version to complement the wide radius turnouts and wide angle crossing. It is not available in 30 degree version, as the other radius curves R1 to R5. But still, nothing prevents to use R9 for any purpose.

Even if it is in German, a Google translation for the 24912 says: "Radius 1114.6 mm. Elbow 12,1°. Gegenbogen for the slim switch and crossing. Also to the building of distances suitably." With a little fantasy, the correct meaning is understood...

They provide a nice gentle curve in instances where they fit. Perhaps M will bring out a 30 degree version of this curve in the future. I'll take some pictures when I get the layout a little further along...I have to dissassemble part of it to install the ramps I just cut.

But only in 2 or 3 piece combinations, not a full 1,114.6 circle! ([^]Hmmm. that would make a nice Helix) From the HO-scale post For Big-Boy Fans Quote: [size=1" face="Verdana" id="quote]quote:The sharpest curve the Big Boys could negotiate was a 20 degree curve. In HO scale, this would be a 40 inch radius curve. That's 1,016mm! So Mä, when are we going to start seeing more R9 radius C-Track? Particularly I wish they made a wide radius Double slip Switch.

Joined: 27/05/2003(UTC) Posts: 235 Location: ,		Hi I have quite a few 24912 (R9) curves, not only for the long turnouts, but also in other places, whenever possible, as they provide the best look. For instance, in my zero level, where I have (will have) my shadow stations, I "reveal" part of the circuit and that is constituted by a long curve with 24912s. It shows up between 2 tunnels. With the long radius R9 you do not notice the polygonal line of the train coming out of the track circle.. Cheers, Nuno

The difference between 180 and 181,5 degree spread out over 15 pieces of 24912 is so small that you can perfectly make a 180 degree R9 radius. I did it and it works out fine. Great for Big Boys or big German steamers such as Brawa's DRG 06! Best regards, Jacques
