Title: Wiring help with an Atlas layout
Post by: styntwin409 on January 21, 2008, 02:30:33 PM
I have the book The Atlas Beginner's Guide to HO Model Railroading, and I built layout #06 from it. I kind of changed the sidings in the middle around a bit, but I kept the terminal track where it should be. The link for it is http://www.atlasrr.com/Code100web/pages/10006.htm (http://www.atlasrr.com/Code100web/pages/10006.htm). I need help wiring it. I don't get how to. I am using DC and have all the required parts but when I wire a section of track it doesn't work. Please help me. Thanks in advance.

The first question is, how many blocks are you using and are they really isolated?  Are you sure that you have not shorted by wiring one section +/- and the next section -/+ within the same block? 
How many leads do you have?

Uh... I put the insulated rail joiners in where they should be. Pics of the plan can be found here: http://www.freewebs.com/thewarriorcodegraphics

Is your common rail really common or did you switch rails at some point?  You have dropped leads to all blocks, right?

Uh... the common rail never switches. And... leads...? Is that the common rail wire? I only attached it to one. How can I get the common rail wire to every terminal?

Ah.  It sounds like you are not getting power to all your blocks.  I must now yield to those who know more about wiring than I do. 
However, each block must have at least two leads to it, one to each rail, and the power delivered must be consistent.

I did a layout very much the same last year using DC.
The common rail only needs one lead but you can use more, I used one for each loop, the inner and outer connected to the - terminal of the power pack. There shouldn't be any insulated rail joiners on the common rail.
The positive went to the Atlas Controller and then there was one lead to each block for each switch on the Controller. It worked just fine.
I have since torn up the entire layout, changed to Kato track and gone all DCC.
If you want to know why just ask!
