My Layout


Questions: Splitting track intoblocks and sections; Dinamo Marklin Z scale users

Netherlands

Hello everyone,

recently we've started to think about creating our own small rail road model. As space is limited, the decision is made to create a Z scale model. But we would also like to let the multiple trains run on the model.

Building in decoder into Z scale trains is quite a challenge, but is seams to be possible (at least spoor-z.nl is doing it (not sean on the site, but the told so on the exhibition last weekend (www.eurospoor.nl)).

But I also heard about Dinamo, which seams a very nice solution for running standard Analogue (DC) trains without modifications on a computer controlled track layout.

One of the first questions I have, how to set up a track layout with sections? As I've been playing Transport Tycoon Deluxe a lot (and nowadays open transport tycoon (http://www.openttd.org/)), I've created a little scenario of how the initial track layout might look like. See the included image.

The idea is to let some trains run a loop, come along a station (in the foreground, 2 tracks). Let trains there pass. And have a shadow station (in the background; 4 tracks), where they can pass and where other trains can then start their round.

I've added some signals, as I would like to add to the track layout.

At least I expect to have 8 blocks:
- 2 at the station (1 for both (platform) track)
- 2 for both blocks running from the normal station to the shadow station
- 4 for the tracks in the shadow station

Where can be good information found about how to set up the blocks and sections? It would be nice to see concrete examples of track layouts, with their blocks and sections. Together with an explenation of which choices hat to be made and their pros and cons.

Are there other users running Marklin (Maerklin) Z scale trains with Dinamo? It is nice to hear and learn from them!

Looking forward to read the replies.

Regards, Tjeerd

This is how your example layout could be set-up

Block 1, 2, 3, 4, 7, and 8 are unidirectional and have 2 sections. One for entering the block and one for the stop-section. Note: the stop section does not stop the train by turning off power, but detects that the train has reached the stopping point, after which the software tells the train to stop.

Blocks 5, 6, 9 and 10 are bidirectional and have 3 sections. This because you need a stop-section at both ends. The middle section can be detected or not. If it is undetected you need to add a passing-diode-pair for this section as described in the CD16 manual.

I've made 2 blocks in both left and right leg of the example layout, but it could also be just one. The block separation and both stop sections in the middle would just disappear in that case.

Block-separation have both rails isolated
Section separations have one rail isolated
It is advised to keep section-separations in the same rail, if possible. It does not matter if they are left or right with respect to the direction of the train.

Kind regards,

Ok, thank for the nice explanation!

Only question I have and even maybe the answer...

Why are the right and left arm split up, into extra blocks?

Is it for making the trains run smoother behind each other? If two trains drive from the shadow station to the 'normal' station, in the same direction, then can follow each other faster?

As only one train is allowed to run in one block. So by splitting the 'large' block into two (/multiple) blocks, multiple trains can run closer behind each other, because as soon as the first train leafs the first block, A second train can start moving into that first block.

Kind regards, Tjeerd

PS: The drawing explains it very nice.

Hi Tjeerd,

You indeed found the right answer to your question ;-)
You have to judge for yourselve if the extra blocks are worth the investment.

Kind regards,
Leon
