Hi All,

After quite a bit of thinking, I've finally started planning my layout using WinTrack. I've attached a photo of my first attempt (sorry, I couldn't get a proper screenshot yet—I took this photo directly off my screen, but I'll upload a better image once I have PC access again!).

I'm currently planning a single-layer layout but realized that I don't want to cut my table for the turntable, so I'm considering adding a second level on the upper side of the layout. My idea is to connect this upper level with ramps in both corners at the ends of the layout.

At the bottom, I'm envisioning a station with three platforms and an additional track dedicated for express trains. Will platforms models from Faller, Koch etc. fit between the tracks? On the upper side, the layout will primarily serve as a maintenance area. Between the lower station and upper level, I'd like to create a street scene with apartments, shops, and more, bringing a lively urban feel to the layout.

I also want to incorporate my 4MFOR models into a small military base area, complete with its own track for military transport.

I'd greatly appreciate your feedback on the layout design, track geometry, and any other suggestions you might have to improve or enhance my plans.

Looking forward to hearing your thoughts!

Hi Omer,
Others who use C-track will know more than I do (I use M-track), but the track spacing at the ends appear to be very close. If a long wagon on the inner loop is passing a train on the outer loop the ends of the inner long wagons may swing out into the path of the outer loop's train. Perhaps a short track between the pairs of 24771 and 24772 would alleviate the possible problem.
Welcome and congratulations on starting your layout. We'll look forward to seeing your progress!

Thank you very much for the reply Brian!

I will look into this, would you happen to have any advice on what track I should use to avoid such a problem? will a 224 do the jo or maybe something else?

While planning it I had a lot of problems with those sections as I feel I couldn't get the geometry right. I want R5 and R4 turns for longer trains but those turnouts don't like that a lot BigGrin

Hi Omer
Like Brian, I think the track spacing far left and far right are not correct.
In C track, large radii then the spacing must be 64.3 mm (Märklin geometry)
So to avoid collisions of long cars in the side curve and also collision with signal, catenary masts.
I am an old Märklinist with a taste for a reverse loop (a track allowing to change de direction of a train.
From what I see the layout is for storing passenger cars and there seem to be no freight trains Am I wrong?

All the above is certainly NOT a critic but a try to help
Cheers
Jean

Hi Jean,

Thank you very much. No offense taken. I am actually glad that you guys are helping me out.

My problem is with turns. I don't really like them since when turning most trains tend to have an unrealistic angle between cars so it somewhat kills the immersion for me.

What can I do to prevent the said issue. How can I achieve the correct geometry while keeping the functionality of coming into the station from the outer track?

I would like to involve some freight too but how can it be integrated while having all of the other scenery parts?

I am willing to start from scratch. The table is 390cm to 175cm just to let you know.

I can't read the numbers on the curved tracks. If the outer track is radius 5 (R5) the inner track would have to be radius 4 (R4) if there are two ovals alongside each other on a double track layout.

Thank you very much for the reply.

Yes the outer track radius is R5 and the inner one is R4. I think the problem is most likely to be caused by the turnouts or their placement. I will try to see if I can solve it somehow. If you have any advice on how to I would appreciate it!

I have only worked with R1 and R2 curves and the curved turnouts that go with them. And if used the right way (the way Marklin suggests) the correct spacing can be achieved. But as said it's not possible to see what's going on in the picture. The switch between the outer and inner track could also be placed before entering the curves.
I agree that longer wagons don't look that great when moving through curved sections and ordinary turnouts. But it's a space issue. Most of us have quite limited space for our layouts.

If you google märklin c track geometry you can find helpful sites and pictures of how things can be set up.

Hi Omer
Train fans like me often lack the space (or have too big ambitions for the given space.
My choice was to have a lot of R1 R2 curves especially in hidden zones and shadow stations; Of course it is not as realistic but allows more track possibilities


Layout space: 390 x 175 cm is quite good, especially if you have access from all sides.
Other possibilities are
- layout supported by feet with casters (it can roll)
- access holes in the layout (usually incide the helixes / Ramps and closed by a removable scenery round cover.
Since I sue Rocrail, I find forming passenger trains, shunting or marshalling wagons is fun

Mashalling


Forming trains

Strangely since I use full automation, I find it fun to create those programs (Rocrail) and watch all the operation but NOT focused on ONE train but on all of them

Cheers
Jean

Thank you everyone for your inputs so far.

I made a revised version that I am attaching so you can see.

I need somehelp with the roundhouse placement and which C track to use for it.

Waiting to hear from your feedback!

Thank you very much!

This is much better I think
Usually a second access to the turntable is better

Hi Jean,

Thank you very much, I’m also pleased with how this one turned out.

I have a question though, I want to have access to from the outer track to the turntable area via turnouts to first the inner track and then inside for turning the locos or shunting etc. how can I make this happen with the current layout?

I will try to add another access to the turntable as well

Thank you very much!

Looks better now. I don't have a turntable but there is a lot of "clutter" in the top portion in connection with the turntable (of course some sidings are needed to make a locomotive be able to move from one end of a consist to another). I would try and get a turnout somewhere to get some action into the middle part of the layout. This could make you get a reverse loop so that trains could change direction freely (and by backing through the loop trains could be turned back to their original direction again).

Sorry not to answer directly but in the real world of trains, you would NEVER have a direct access to the steam depot EXCEPT if you have an underpass to reach it.
The reason is NEVER block the mainline circulations with side movements (locos going to or coming from the depot.
In my favourite railway station Paris Saint Lazare, there were two underpass accesses (under a 10 track mainline) and two turntables
This station at the time was Paris' largest

Hi everyone,

Thanks so much for all your input—really appreciate the help!

After considering your suggestions, I've decided to leave the mainline access as-is since, as a few of you pointed out, it's actually quite realistic.

Regarding the turntable, I’m going to keep it at the top edge of the layout. I don’t want to shift it inward because there’s going to be a street running down that side. Rather than cutting into the baseboard, I’m planning to add a second layer on that top side for the turntable and roundhouse area. I’ll connect it with gradual ramps from both ends of the table. The main station will stay on the original level.

If you have anymore suggestions regarding the layout I am all ears.

Now I’m turning my attention to signaling. Since I’m modeling Epoch III/IV, what types of signals would be appropriate? And where should I be placing them for a realistic setup?

Looking forward to your thoughts!

Hey everyone!

I recently made a few updates to the yard and passenger platforms, and I’d love to hear your thoughts! I’ve got two different alternatives—what do you all think of them?

Like I said before: there is a lot of "spaghetti" in connection with the turntable, and lots of track leading into and away from it. I'm no expert but I would imagine that in many cases there would be just a single line of track leading to a turntable? You have to think about and imagine what kind of action you want to be able to perform in the top part of the layout. Access to industry, places to park freight and passenger cars, a fiddle yard, a return loop etc. No criticism. Just things to consider.

Thanks so much for the input! The challenge I'm facing is that on my layout, the upper section—where the turntable and yard are—is going to represent a mountainous area. I decided not to cut into the baseboard for the turntable, so instead I'm planning to build it on an elevated platform. There'll be a retaining wall or similar feature separating this area from the city section I want to include.

Unfortunately, due to space constraints, I can't really shift the yard or turntable more towards the center without compromising the city plan, which is quite important to me.

As for the clutter you mentioned—I'd really appreciate any ideas on which tracks or lines you think could be simplified or relocated. Open to suggestions!

Good idea to place the turntable on another level. But in that case you'll need to remove it from the current plan and put it on a new plan in the layout program and you'll need to add a line of tracks going from level one to level two (the ascent must not be too steep). And then you'll need to find out how much track you want on the upper level.
About the city: most model railroaders just want the "illusion" of a city. A train station, a main street and a line of houses and then some houses in small groups in some places connected with narrow roads and also some groups of trees and other landscape things etc. The main thing is usually having interesting train driving possibilities and lots of tracks... Main stations, secondary stations, staging yards, industrial yards take up a lot of space both in real life and in a model train setting.

That is true, I heard maximum is 2.5°-3° gradient for C-Track. I ordered the parts I need according th layout Vol.3 and then see how everything fits, after that I will make the modifications.

My plan is to have a “high street” just outside the station with apartments ands shops. The street will stretch from there as you said like an illusion.

WinTrack is great but since I’m a bit old school I need to see it on my table to decide or modify certain things. The main issue is since I live in Turkey is hard to source parts or tracks due to customs and high taxes that is why I was in a hurry because yesterday I came to Germany so I will get everything from my Märklin dealer friend here.

The next phase I am planning on is catenary and signals.

I have a quick question, where do you think I should put some uncoupling tracks on this layout?

Thanks again everybody for their inputs, I appreciate it!

Funny you should ask about uncoupling tracks. I've just installed one in my layout. It's operated by my CS3 via an m83 decoder. (The m83 can handle four turnouts with its four terminals but each terminal can handle two uncoupler tracks).
I will mainly use the uncoupler for pre-uncoupling: backing the locomotive into position, uncouple and then back the line of cars/wagons into a free area in my staging yard and then go forward because the cars are no longer attached to the coupler of the locomotive.
The uncoupling (both forward and in reverse) isn't without potential problems. If the locomotive has a skirt or a plow it can be hard or impossible to make the uncoupler work (because it hits the skirt or plow and can't lift the coupling all the way needed). Some cars and wagons also have hooks or other elements fitted that can hinder uncoupling. So these hooks might need to be removed. You most likely also have to have the same type of coupler between the locomotive and cars to make it work best.
It will take some consideration and planning to find the best place for one or more uncoupling tracks. Should it be placed where an uncoupled line of wagons can be reached from both ends and then be pushed (or pulled) from both ends by the same or another locomotive? It can also be used to separate single or more cars from a consist of course.
Also notice that the uncoupler needs to be placed on a straight piece of track, so that the two items to be uncoupled are facing each other in a straight line... and also in a position where you can see what's going on.

Rather 2.5% - 3% (instead of 2.5° - 3°), as 2.5° equal more than 4% and 3° equal more than 5%, both already being quite steep.

For illustration: The inclination of the ramps in the attached Märklin brochure (see PDF, pages 10 & 11) corresponds to about 3.5% (or 2°).

... a small update on uncoupling engines (locomotives) with plows or skirts. I found on an engine like the marklin 39675, a Nohab My 1132 from the Danish State Railways, that has a snow plow quite close to the coupler, that if the uncoupler is activated several times while the engine moves forward it will uncouple. To avoid the engine and cars connect again when backing up it's necessary to have the mechanism activated repeatedly again, and so the shunting can continue. The uncoupler has a thermal protection that will make it pause if it overheats due to prolonged activation.

Later edit: backing through curves with pre uncoupled non Marklin equipment may result in derailments because the buffers can get entangled. :-)

Thank you very much for their reply, at this point I think I’m going to wait a little on this topic and build the layout and then start testing it, after that I will come back to this uncoupling track issue and work my way from there. There is a lot of loco and car variations on my collection so I have to test them.

That attachment is a lifesaver, thank you very much, according to my calculations I need around 129cm of length to achieve a minimum of 45mm height difference between the layers.

I was at Dortmund INTERMODELLBAU today. Took some pictures of the Marklin layout and inspected it, that gave me a couple of ideas on how handle the ramps and the layout maybe some modifications etc.

As of today I will move forward with the Marklin signal system but I’m open to your ideas on this. For turnouts I am using the Viessmann turnout motors (4568) due to unreliability of Marklin motors I read online and smooth operation of Viessmann turnout motors.
