Wiring Help for the MDRail Pope's Creek Branch in HO Scale

Damon Curtis
 

Hello!


I have been quietly observing the group and the conversations that have transpired over the past several months. I am optomistic that, collectively, you all may be able to help me to determine how to approach wiring my layout (which is currently under construction) for DCC. I thank you in advance for any feedback.


I have created a folder called " MDRail Pope's Creek Branch" in the group's file section and have uploaded several drawings for you to review. Although I have been modeling since I was knee-high to a grasshopper, DCC might as well be a foreign language to me; so please, forgive my ignorance in advance. If you all would take a look at my drawings and let me know what approach I should take in getting this thing wired up, I would greatly appreciate it! Thank you again!!

Damon, are you planning to have circuit breakers feeding each block?

 

The ‘Brandywine Jct.’ block is a reverse loop; you’ll need an auto-reverser type of circuit breaker.

 

Also, wire the turnout feeding Brandywine Jct. to the ‘Staging’ block.

Then, double-insulate both the normal and diverging legs of that turnout.

You’ll also need to double-insulate the track where ‘Drink’s Run’ joins ‘Brandywine Jct.’.

 

I don’t understand your use of the terminal blocks for the DCC wiring.

Hi Paul,

Thanks for your response! To be honest, I have no Idea what I am doing I created blocks and drew terminal strips based on research I did online. That is why I posted here :-). 

I read somewhere that I needed to have track feeders every 24 - 36 inches . . . That is why I assumed terminal strips (to distribute the feeders). I was told to use a specific product for the blocks; but, I do not recall at this point . . . . Basically, I am clueless . . . literally . . .

Damon,

My 2 cents from years of experience in home and club layouts. First I assume you are using flex track. 

Each section of flex track should have feeders. The rail joiners should only be used to align and connect 2 pieces of track. Rail joiners should not be relied on to pass electricity. Over time with expansion and contraction rail joiners will fail at passing electricity. 

While laying track attach a feeder to the turnout frogs even if you don't power them initially. Much easier to install the wire when laying track versus retrofitting.

While the internet is remarkably handy, it's not the place to start. Kalmback has updated its DCC book. Get a copy and read it until you're comfortable.

Damon, a good place to start reading is here:

http://www.wiringfordcc.com/intro2dcc.htm

However don’t get overwhelmed with detail to start with.

Good suggestions by the other responders.

 

The basic idea of DCC wiring is a two wire bus (two different colors of insulation) running under the track arrangement so that track feeders can be attached to the bus. The bus should be a heavier gauge, like 14, while the feeders can be 20 to 22 gauge hook-up wire.

A lot of different opinions as to one feeder per track section, or, solder the joiners and spread out the feeders. Just don’t rely on feeders for electrical connection.

Also, choice of solder feeders to bus, or, use connectors.

 

If you’re a lone user, blocks are not essential for DCC, but may make trouble shooting easier.

 

Keep asking questions. J            Paul O

Paul, too late to not get overwhelmed...lol! I am using flex track and do not intend to rely on traxk connectors to transfer electricity. My operational plan calls for 1-3 operators; however, I can accommodate up to 5. Mainly, I want to be proactive in making smart (correct) connections up front so that the potential for problems is minimized.

Hi Damon,

I think your question is more generic than it needs to be, and that will mean you will get answers that do not necessarily relate to what you want to do. That's the rub: from the description, we don't know what you what is is you expect your layout to do.

For instance, the requirements for holding operations sessions with a multitude of persons may be very different from those involved with running trains controlled by computer. Additional complications would be involved if you need signalling to work. Both of those will need occupancy detection, which is a big subect in itself.

The size of the layout is another thing. As is the scale you're working in. That's to do with circuit breakers, command station power requirements, wiring guage. There are so many subjects! The knowledge on all of them is available in this group, and in the more specialised ones depending on the hardware you choose to go with. But really, telling what you want to do is the first thing. Technology will then have to make that happen. Not the other way round. You'll get more targeted answers if you can tell something about what you want to achieve. How you see you operating your layout, eventually.

Most of all; have fun!

You might find the DCC wiring presentation located hear informative.  Used at many NMRA conventions.
