Bexhill MRC DCC Group Automation Demonstration Layout.
« on: February 03, 2019, 05:06:35 PM »
I have over the past years put together several small boards to demonstrate various aspects of DCC control such as Turnouts, Signals, Programming etc. my thoughts have now turned to building a working layout that demonstrate how all of these various components are joined together. To this end I produced the following for consideration by my Wednesday evening DCC Group.

Scope

1)   It will be in N Gauge so that the completed project baseboard could be taken out for demonstration. This initial design is 800mm x 1300mm. we would run short 2 car DMUs or Push/Pull 0-6-0 two car sets of similar.

2)   The build of non DCC related items such as baseboard, buildings and scenery could be done by volunteers outside of the normal Wednesday meetings thus saving the real work of DCCing for some of our normal meetings.

3)   It will be complete with Block detection so that true computer control would be implemented, and extended to automatic control including ‘Hands Off’ Timetable running. Giving us the opportunity to discover and learn how various software packages handle those tasks involved.

4)   It should be ‘See through’ so that all of the active DCC components are viewable. It may be necessary to mount some of the electronics above the board. 

It will not be all time consuming and I would expect the normal DCC discussions and demonstrations will run concurrently, so that new members or those with no interest in a project would not feel left out, I hope that there will be something for everyone.

I do not intend for us to be a layout building group as we have enough of those at the moment, I see this as a chance to bring together many of the concepts that I have presented in the past.

Following is a track design that will give us the scope for all of the above along with initial costing.

Costs could be reduced if any of you have leftover materials or parts from your own projects that you may wish to sell at a lower price or donate FOC.



End

Following some discussion we settled on this broad outline.

The baseboard will be a ply frame 1350mm * 800mm *150mm deep with inset high density foam top covered with 3mm cork tiles.

Could I ask those of you who have a hatchback type car to measure the load length to ensure that should you wish to transport it that the 1350mm length will fit.

This construction I will enable us to mount the turnouts and their actuators (motors) onto the tiles before assembly onto the baseboard.

This means that they can be wired and tested by members at home before installation!

As I want some of the actuators to be visible these turnouts can be mounted onto 3mm clear Lexan which is easier to work than Perspex.

This way of showing the workings will unfortunately mean that we will be unable to use Kato track because all if their ‘workings’ are hidden inside of the turnout.

Therefore we will use Peco Code 55 track and Turnouts.

What would normally be the Back Scene board will be used the mounting board for all of the electronics making them fully visible to all.



In front of that will be a removable back scene.



The next phase will be to get some materials together.

as this is a DCC demonstration / testbed, would it be better in the DCC thread?? more offers there?

Sorry, I don’t understand, are you building this, or asking for help building it, or offering it is an ‘open source’ design for others to copy?

OK I thought my preamble regarding the intent was that this is a Bexhill MRC project, I cut and pasted several emails to our club members and maybe in context some of my thoughts have been missunderstood by Forum members.

So yes we are building this as an exercise for our (BMRC)  DCC Group, and I will share our progress here.

When completed perhaps I will offer to visit local clubs with this portable demonstration to give other railway modellers an insight as what DCC is all about.

Sorry for any misunderstanding I may have caused  :-[

Absolutly,  but I thought that I could start under this Thread whilst initial contruction is underway, and then ask to shift it to DCC Thread at a suitable time.
However if a Mod would like to move it now then I am agreable.

Fair enough, it was comments about measuring the size of boot openings in hatchbacks that confused me!

Sounds interesting though.

All of the track is laid.



Underside



The ‘See Through’ turnout motors

Tortoise Top.



Bottom



Peco Top.



Bottom with frog polarity switch.



This is how I envision the depiction of wiring detail to look on the back of the layout.

Digitrax BDL168



DAC20



This will be the actual wiring detail.
