With regard to CV's and decoder programming, it is actually much simpler when you use a computer.

JMRI ( which is free ) provides a tool called DecoderPro for programming decoders.

You simply select the manufacturer and model of decoder, fill in the forms on the screen, and write the settings to the decoder.
It uses the CV's "under the hood" but you do not need to know anything about that to be able to use it.

If you can find somebody nearby who has DecoderPro, that may be the simplest way to program your decoders.

I have included 2 examples of what you can do.
Apart from changing the address, the only thing I have done so far is to set a "momentum" value.
This sets a damping when using a throttle, so starting, stopping and changing speed is always very smooth even if you are heavy handed with the throttle changes. I find it a very useful aid to realism ( although it does make stopping a loco in an exact position more difficult )

The pic below shows where this is set using decoder pro.



You could do the same thing by finding the CV you need to write to to set momentum.
CV's are documented here,  it looks like CV3 and CV4 for the speed damping.
http://www.dccwiki.com/Configuration_variable#Mode_Control_.28CV29.29

Below is another example.
Here  you can set how the decoder  responds to the throttle - for example you could make it sensitive at low speeds and coarse at high speeds by changing the sliders in the form. Again, it will use CV's . but you do not need to know what they are.

 :thankyousign: for your reply it is very interesting but i don’t see how that will help me really. My controller is a Roco Z21 Black.  :hmmm: a thought has just come into my head, i am sure the unit has the capability to connect to a computer by an ethernet, so i should be able to program them once i have put the decoder in to a engine shouldn’t i. Or am i thinking total rubbish, it is really all new to me, but i love trains and what to get to know a little bit more and understand more about the hobby.

 :thankyousign: again.

I am not really able to help with the details but if you look at

http://jmri.org/help/en/html/hardware/roco/z21/index.shtml

It does seem possible to connect your unit to a computer and use jmri.

There is a jmri yahoo group where you can seek help with that if you need it.
The details are beyond my knowledge but happy to be able to point you in the right direction for help.

So, just a quick update on the layout. After more hours than I care to admit to, I have pretty much finished my next phase objective of automated running. I have written a Jython script  in JMRI which enables trains to run around, changing points as needed for their route, and (usually)  not colliding.

 For example, my layout is essentially two inner loops and two outer loops, but with some sections of the loops being common. I can run a train on each loop,  with the trains changing points and waiting if necessary on the common sections of the loop. In addition , whilst that is happenjng, I can run a train out of the sidings in the centre of the layout, crossing the inner loop to get to the outer loop.

Next phase is to get signalling working. The software that drvies the signals is actually already in place. All I need to do is add the hardware so I am hoping this should not take to long.

I have also started thinking about adding at least a hint of scenic modelling, and will start with adding platforms. I plan to do this with the peco platform sides, and plasticard top with some sort of printed paving on top.

Slowly, slowly but going in the right direction ( unlike some of my trains if I get the route control wrong .... )

I think it's essential we see a vid of this intriguing running ;)

Thank you for your interest.

I may try and put something up on youtube in the next week or so if anyone else has any interest.

As requested, I added a video to give a flavour of the layout running under computer control

Ta muchly for that - very impressive.

The grinding noise is the electric point motors

Just  a quick post showing some progress

Built and added some platforms, and installed a working 3 aspect colour signal system.





And had my first attempt at ballasting



I have also completely rewritten the JMRI script that controls the running of the layout

Hi,

Just came across this thread. The electrics you have done look amazing but way beyond my brain capacity.

However, as you seem to be getting on with the scenery, which I can understand, just to say all looking good and looking forward to more.

Cheers weave  :beers:

Completed adding ballast to the sidings.
Deliberately tried to not lay it flat but heaped it between adjacent tracks.
Two small lumps came up when I hoovered it but 99 percent has stuck ok.
Might add a bit of weathering, oil or green growth at some point.

Thanks to all who previously posted ballast articles because I followed the advised methods to be able to do it.

Ballast, ballast, and yet more ballast.

I go to sleep thinking about ballast.

I wake up thinking about ballast.

I am even considering having ballast for breakfast.

Perhaps it's time that I took a break......
