Hello,

Does this meet your requirements?



I'm not that familiar with C track as I use K track.

Hi!

S shaped double curves with 24130 are the most difficult combination for rolling stock - not even all Märklin rolling stock can handle that.

Here's a reversing loop with some straight tracks in between.

Hi there,

Building on Tom´s reply, here comes a more condensed and space-saving version (requiring 76 x 121 cm), even with slight easements at the beginning of curves, completely relying on R2 radius plus a short piece of straight track (24094) "in-between" in the S-curve area.

I defused the R1 S-curves of the two reverse loops on my layout either by inserting only a short straight track (either 24064 of 24077) or by "counterbalancing" a R1 with a very wide radius track, as R4 or R5, instead. This works fine for all kind of motive power and rolling stocks, European and US, coaches and freight cars, both pulling and pushing.

Cheers - Ak

Hello Ahmet,

I saw your request earlier today at my doctors, while reading the forum on my phone. Now that I'm home in front of my computer, I can post a useful reply ... at least I hope you find it useful

I keep a number of re-usable track patterns, including reverse loops in my library of SCARM track plans. Below are a few images of those patterns. Hopefully the JPEGs have enough resolution so that if you click on the images below to enlarge them, you should be able to read the track part numbers. Please note that all three of these patterns have a straight section of track to mitigate the S-Curve effect mentioned in one of the previous posts.

The first image is an Industrial Radius reverse loop that I needed for my layout. Since C-Track does not have this radius, I had to use the K-Track Industrial Radius track (2210), along with two of the 24922 K to C conversion tracks.
This second image is the smallest all C-Track loop that I have come up with that I am also happy with. It uses mostly R1 radius 24130 track. There is one R2 24230, that matches the radius and number of degrees (30), of the 24612 turnout, combined with the 24206 R2 six degree track.
The final image is an all R2 reverse loop. This is the smallest radius reverse loop I use on my mainline tracks.
Regards,

Dear rrf and Alsterstreek thank you for the details. I am super happy. An economic reverse loop design would probably one of my final exam question at the Marklin Track Geometry 101 class :D

Cheers!

FWIW I prefer the aesthetics of symmetry.

This image offers the smallest footprint for a C-Track reverse loop, however I would usually start with a base of R2's and throw in R3s for progressive lead in to curves.
In doing so the "S" is further dampened and there is a bit more room for the loco storage yards

(The dimensions shown are to track centre - add x:20mm and Y 40mm for the C-Track roadbed)



And then for utility ...

The second is monster reverse loop that I only can see in my dreams for now :)

...and it works in m track
