Well here are my current station throat designs. Allows for a uni-directional platform track from each direction, a bi-directional platform track, bi-directional passing track and a bi-directional freight track. The only issue is on the left side throat there is a 24912 wide curve coming off a wide radius curved point (instead of 24315) but it was the best option there as the alternatives looked terrible. Otherwise all OK. I am not convinced with the right side station throat with that curved point, it doesn't look terrible but not great either. The 24611 track and the 24330 will lead to some freight sidings, as that last track (5) is the bi-directional freight track, you can see a pocket off the left side for the changeover.   |

Right side with R9 switches instead of the curved switch, definitely a better look.  |

Looks good! Just one suggestion- not better or worse, but you could save a bit of space (and make the station longer) with this...  I have abused the curved turnout geometry somewhat, but it works in practice. - H |

I agree. The Marklin C track offers a good quality network construction system for appearance and structure. I have only one very little regret. - discrete sockets for B and O on the side of the ballast. It would be easier to implement connections.

A separate clip on component that you snap onto the c track similar to some signals which connects to the B and O below and provides those sockets would be ideal , then there isn’t the need to make special variants of various track pieces. |

I wholeheartedly agree. I am still operating a "carpetbahn" whilst planning my permanent layout when space permits. This does have the advantage that every time I put the track together I try out a new configuration which teaches me what works and what doesn't. However, I really detest trying to push the spade connectors from my 60116 box onto the nearest track piece. Sometimes they just slide on, other times I spend ages pushing them with pliers. Also the red and brown wires sneaking out under the plastic ballast doesn't look like it was well designed.

Has anyone tried making the missing 9.3 degree curve piece from a 24215 or 24315? |

There is no Double Slip Switch that matches the geometry of the 711 0r 712 turnouts. Or do I misunderstand?

I have just joined this forum. Since I have read concerns about the lack of a three-way slim switch and the space needed to solve the problem, someone may be interested in how I have suceeded to pass from one to four tracks in just the double length of a switch. Of course some "surgery" and cutting of the side plastic is needed. I was afraid of spoiling something when I tried, but it is really easy to achieve using just a Dremel or similar device. I show a picture of the result, so that I am ready to explain the procedure at request.

Yes it's well known you can omit the 24071 intermediate track piece to shorten the turnout distances but it involves cutting the roadbed.
Thanks for sharing your picture.
If you look at some earlier posts you can see an example of cutting the 3-way switch to also shorten the turnout distance. |

Thank you for answering, applor. I have read a number of posts here indeed, and learnt a lot from them. The solutions I have seen (e.g. posts 101, 114, 115, 117, 119) are really useful and original, but they imply either “major surgery” (not just biting an angle of the roadbed externally but cutting through a stretch both of plastic and metal pieces and later gluing and soldering) or using tracks in R2 (as the 24630, 24206/7), or both, giving up with the charm of slim switches and their wide radius. I find some advantages in my suggestion: 1. Four instead of three outputs. 2. Saving one switch engine, since one lever moves two switches at a time, as can be seen in the image below. This particularity, as well as not using a number of short tracks, saves money too. 3. Distance between track centres is 49,5 mm, practically true scale. I have just modestly tried to contribute with another feasible idea. PacoM

Now, I would like to show how these switches (in red in the image) may be used in an end or passing station. The upper layout has been actually built and is inspired (a bit simplified the right part) in the end station in service in my town until 2018. The lower one intends to show the suitable track combinations, and track separations that may be achieved with them. New straight tracks may be added where vertical lines have been drawn, so as to reach the intended length. Regards. PacoM

Thankyou for the contribution, I must say I did not realise how involved it was to fit the wide radius turnouts without the 24071 spacer. I used K track for my layout but my new hidden storage yard is in C track (it was cheaper) and I won't be using the 24071 for that construction to save space so your post should be quite helpful when I get to modifying the track. |

To put it into a context, the layout schematic would be as follows, which explains the positioning of the 24530/24330 curve pairs:  |

Yet another possibility for a "Y" or "triangle", inspired by Alsterstreek (and partly copied from him)

And, for those who love slim turnouts and curves, another possibility. Notes: 1. The 064 piece next to the left crossing will need some side cutting. You can see a gap of 2,5 mmm that may be corrected with the side tracks. 2. In case you place the correct 071 piece, the result is a larger overlap (3,4 mm) instead of the smaller gap.

The outer curve : 24115+24215+24912+24912 Hello Alsterstreek, It’s nice that you showed us the different track arrangements that can be make with Märklin’s C track system assortment! Your track arrangement (above) looked similar to what I have created a couple of years ago. Except I did not use the curved turnouts in my arrangement. What you see in the picture is the entrance into my Hamburg station from the east side. When my trains travel that section of track the slim turnouts guarantee the smooth transitions to either of the two tracks on the mainline.

Thanks Michel, Your double crossovers are very nice. I didn’t share the “context” on my layout, since thread is more about the “mechanics” of unusual C track combinations. My yard throat is in a curve - see photo.  Continuing adjacent to the R1 turnout with the curved segment of a slim turnout as easement results in a smooth train run. P.S.: The 2461x “stub” turnout leads to freight car sidings, while through traffic is using the wider curves. |

You think double track mainline, I think shunting puzzle (and geometry tricks). This is the „conceptual“ C track (and not a track plan) topic, after all.

For people seeking to know the meaning of double track life: half of my post # 234 experiment with a couple of curved turnouts to swing back and forth from one track to the other.  2471x, 3x 2467x, 1x 24912, 1x 24315, 2x 24230, 1x 24207, 2x 24306 & 1x 24107 (in reverse numerical order). |

Hi AK,
The switches (turnouts) between multiple tracks have real-life application on some (most?) of the Class 1 railroads in North America.
One of the classics I know something about (Norfolk and Western Railway) routinely had passing trackage using double track switching to three tracks and after a few (3? 4? 5? 10?) miles switching back to double track.
It allowed faster trains to overtake slower trains without one having to stop.
Due to advance Centralised Traffic Control (even back in steam days), the centre track was used for trains travelling in either direction.
I am unable to find a photo on the internet although I do have some in books.
This track arrangement is quite easy to do in C track with slim turnouts.

Hi all, I am looking for a solution to close these gaps, otherwise a plan for a super elegant finish to my question. I would like to have a triple staging yard served from a single line of entry. Happy to use R1, R2, R3, but don't rule out R4 curves either. AK, I am hoping that you will read this and provide some innovative ideas !   Regards  John

Here's a standard geometry way to do it... given that it's a staging yard I have just used standard tracks with nothing fancy - I've changed the arrangement of the turnouts so that the inner track is closer in length to the other two (highlighted in yellow)...  Do you have a size limit? - Herman |

or here's an alternative more similar to your original, but moving the '206 tracks (in green) like this means that the standard track spacing is (nearly) maintained, and so the R1, R2, R3 concentric curves can be used as normal...  or here's a compact option with no small or unusual pieces, and moving the '224s to the wrong end of the curve (in green below)... with the downside that the tracks in the curve approach closer to each other than standard (circled in red):  |

Hello Herman Yes, I like this option. My dimensions are 2.6m x 1.5m so this will fit. The single line comes from the line long the garage wall, so this will be fine. Thanks you. Regards John
