I include an image from a Marklin Youtube video.
What would be the distance between the parallel tracks and what would be the length of the whole set up, 360mm?

Thanks in advance

Hi Eduardo/All,

I tried the example in the YouTube video and got the same results as you but I managed with this configuration.

Thanks Ross. Have to try this, but just looking at the diagram, wondering how the 064 fit without being able to remove the embankment.
Is that 64.3 mm between the parallel tracks and 360mm total length?

TIA
Eduardo

Sorry guys, but none of this works without manipulating - or mutilating - straight C track segments (with 24188 being a preferred victim) - see post #320 of below thread:

When I set it up in Scarm it shows a length of about 79 cm and a distance between the tracks to about 9 cm. But the distance is more like 8 centimetres because Scarm shows the C track a good deal slimmer than it is. The distance from center to center of the parallel tracks is about 12 cm and the distance from center of a real C track to the outside is 2 cm. So 4 cm should be subtracted from 12 giving a distance of 8 cm.
The 24071 has a detachable part of the ballast that should make it fit.

So even the Youtube version by Marklin does not work?

Just to clarify: my test in the layout program Scarm was based on Ross's picture.

Dear Eduardo,

Would you kindly provide the link to this Märklin YouTube video?

Here the link.
A somewhat idd video as it talks about a double crossiver with standard turnouts then shows other set ups.

My initial question is about the distance between parallel tracks and the tital length.

When Ross came up with the similar set up, but with wide turnouts, I then asked the same about that set up.

I will probably avoid any criss crisscset up, but was curious about the geometry and then surprised if none of these work unkess you do surgery to C track, which is something I want to avoid.

Again thanks fir tge input
Eduardo

ALERT !

OMG, the slim Hosenträger track planning using 24172 at the end of the video is plainly wrong, I am at a loss as to how Märklin could have published this ! There is a 4 mm gap... And unlike the presentation of the standard configurations at the beginning, only the software planning is shown for the Hosentraeger, but no actual track segments; otherwise, the impossibility of the 24172 combination would have been noticed. 24172 is too short and 24188 is too long.

English version
2:45-3:05

German version
2:59-3:32


There are various comments by German modelers about the 4 mm gap and how to solve this by creating a "24176" by cutting a 24188 - see link with an illustrated Dutch example:

https://wiki.3rail.nl/pa...en_met_kleine_aanpassing

If doing so, the overall lenght is:

236.1 (24711) + 70.8 (24071) + ca. 176 (24176*) + 70.8 (24071) + 236.1 (24712) = ca. 790 mm total length; the track distance should be 118 mm.

* shortened 24188

Hello Everyone,

All the suggestions show that C-track isn't perfect all the time.

track_crossover_2.png


My first suggestion drawn with a tolerance of 1mm requires cutting and I'm not sure this is possible because I don't have C-track to experiment with.

The second suggestion added by Alsterstreek, provided by Marklin isn't perfect as the top 24172 has a thicker line on the left which means the track piece is too short.
Using a tolerance of 1mm the tracks won't join but if the tolerance is increased to 2mm the 24172 tracks can be joined. The gap is small and will work with real tracks.

This shows with any track design software, the tolerance used is a factor if the design is to be successful, the proof is to be able to realise the design with physical elements even if it involves cutting track.
We all have to interpret how the track design software works for good designs.

I'm increasing my knowledge designing layouts with the good examples provided by others.

By looking further into the matter I can see that the slim turnouts need two 24071s, one at each branch. The ballast can be removed on the sides and the turnouts come with a specially designed part to fill the gap.
In Scarm I could only manage to fill the straight gap between the two turnouts top and bottom (now with a 24071 in both ends) with about 1.2 to 1.5 millimetres missing.

This was the variation I built in 2012.

(Edit: Unfortunately the Svenskt Mj forum has blocked most international IPs to avoid attacks and spam.)

Cutting two Märklin C-track 24188 to appropriate length and a 24640 cross, and finally trimming the slopes

Today expanded with two slim double switch and a R3 curved switch.

Good suggestions all. Cutting the side of a track, in order to place it inmediately after a slim turnout, is perfectly possible, and easy to do. Here is an example from my layout, where two pieces cut short to 40mm have been placed after the turnout. You can see the cuttings on the left of the line drawn in red and a bit further.reemplazo 071.jpg.

And beneath, another possible solution, cuttings to be made where I have drawn red points, and shortening because of the overlays shown in violet. I think this is the example posted by LeoArietis. In red, an equivalent length with regular track pieces.Hosentrager.jpg

Yes! Paco posted the exact variation I use.

It's been hassle-free for the whole time since 2012. Even better looking after adding some C-track colored ballast to cover the cuts.

UserPostedImage

If not wanting to cut slopes, use the regular 8 * 24071 and cut 24188 to length. Drawback is even wider parallel distance and 8 extra 24071.

One could really make an argument Märklin should make the cross 24640 with the same sort of removable slopes like 24071, and then all we need is a 36 mm straight track to fill the gap between two 24071!
