Hi!

Anyone who knows the geometry of the new curved turnouts?
I'm drawing layouts i AutoCad and make my own parts (blocks).

The description only says R3 30 degrees inner curve and that it will end in a 64 mm spacing.
Is the outer curve also R3, but 'pushed forward'?
When do you reach the 64 mm spacing? In end of the two #24315 required?
Regards

The geometry seems similar to that of the R1 curved turnouts. Each turnout has two 30 degree R3 curves. The "inner" branch is a simple 30 degree R3 curve and the "outer" branch is a 64mm straight followed by the 30 degree R3 curve. Adding two more 30 degree R3 curves on each branch achieves a 90 degree curve with the two tracks at 64mm spacing at the far end.

Thank's Ray.

I'll try to draw it that way.
To get to the 64 mm spacing it means you have to use 4 # 24315 ...

... and (before trying to draw) it seems a little odd that the outer parallell should be a R3 and not a R4.

If you go to www.railway.zone, on the latest blog there is a review of these points and he gives their geometry.

Thank's for the link.
However, I could not fine more detailed info than what's on Märklins site ...

Some drawings I see for these turnouts suggest that you can use them to assemble an inner curve of R3 and an outer curve of R4. Others show that both curves will be R3.

Has anyone used them and if so, can you provide me with more geometry information for these?

Thanks,

Jim

I have almost all Märklin and mostly HO, although I do have a small number of Z gauge trains!
So many trains and so little time.

There are R1 curved turnouts and there are the new R3 turnouts. Both tracks of each turnout have the same radius.
The former can connect R1 with R2 or even R2 with R3.
The latter can connect R3 with R4 or even R4 with R5.

The curves will be padded with short straight sections to give a larger radius in total, but the switches are still R1 or R3 respectively.


Connecting R3 and R4 with the new turnouts leads to an "R4" curve with R3 curves and 64 mm straight track in between. Doesn't look smooth when long coaches pass through such a curve.

Thanks - that is what I thought, but I wanted to be sure before I bought any of them. I saw one drawing that showed the outer curve composed of two 24415 and one 24430 to make an R4 curve. But there are no 24415 curves even being made, so I was suspicious!

Jim

There is a new curve track that is coming out to extend the wide radius curved turnouts. This 15deg. curve track is R3 and so is numbered 24315. It works like the 24071 used with the 24711 and 24712. It is not a straight track. I've got them on order along with the new turnouts but they keep putting off delivery.

Roger

Roger,

I think it is meant that integrated in the turnout itself there is a short straight section on the outer radius, which sometimes leads to an ungraceful travel of locomotives and cars through the outer radius curve of the turnout. I have observed this with K and C track R1 curved turnouts, I am assuming the overall structure of an R3 turnout would be similar.

That's it.
And for use between R4 and R5 more short straight tracks will have to be added.

Please refer to the 2015/2016 Marklin Catalogue pg 245

With surgery excluded ...

Unlike the 24671/24672 R1/R2 curved turnouts, there is no option, with the 26771/24772/24315, for the mid arc insertion at the 30-60 degree location of a 90 degree turn.
This eliminates the possibility of the "ungraceful travel" due to a "bit of straight" in the middle UNLESS you create it yoursellf at the entry/exit
