    Been researching Atlas Code 83 crossings to see how they are wired at the factory. Found Shinohara and PECO diagrams, but nothing for Atlas. Anyone know for sure how they are wired or know where I can get a diagram? Checked Allan Gartner's site, didn't see one there either. (Unless I flat missed it). My other option may be to head over to the hobby store and see if Atlas posts one on the back of the package.

    Thanks..

    Well, out of first hand experience, assuming your Atlas has the 4 plastic frogs, you will likely experience stall outs on them if you try to creep across them without 'keep alive' in all your engines. Also, some, if not all, have too narrow guardrail channels which will 'grab' some wheels. But I can't speak for the other makes. I hear crossings are very hard to hand lay. But it could be the only way to solve the problem. I do like Atlas switches, though, for 2 reasons: To me they look the most US proto, more than say, Peco or Shinohara. And their frogs can be energized. The black coating rubs off and reveals that they're metal. My theory on the black coating is that it protects the frog from oxidizing/pitting if hanging on the dealer display rack a long time... M

    Thanks for the reply. I solved my problem this morning. I am isolating previously wired sections of my layout for both power districts and detection blocks. The last section I'm working on has 2 Atlas crossovers near each other, and I have them "gapped" as I should. I have been disconnecting all but one power district and using a voltage meter to check for any back-feeds I may have missed during this isolation process. I was getting voltage on 2 sides a crossing I should have not been getting voltage on. So I was wondering how that crossing was wired since I didn't have the package or diagram anymore. However, this morning, I found 2 feeder wires to track sections I had not checked and they were the culprits, backfeeding to the wrong side of the crossing. They were promptly re-assigned to their new power district.

    After I disconnected them, all rails went to 0 volts where they should and all rails stayed at 14 volts where they should. So w/ everything FINALLY isolated, I can check the wiring w/ the voltage meter and checks out fine.

    Cool, but I'm lost as to your initially wanting a wiring schematic of Atlas crossings, and now talking about power districts. I fail to see how that corrects the plastic frog problem I mentioned ?

    You initially said you were asking the forum for an Atlas crossing diagram/schematic. So, why do you now post a Shinohara schematic ? I mean, why did you even start the thread in the first place if you obviously were ultimately going to accept a diagram you already had and which was not an Atlas diagram ?? On top of this you post it up as if I/we were asking for your help !! You were, not me/us out here, trying to help you..

    Because that is what I was looking for and could not find. I was hoping someone had one. Something similar in Atlas, that is why I started the thread. The post above I am merely giving examples of what I found in Shinohara and PECO certainly not representing that I accept them as a substitute. But, I got it worked out w/ a muilti-meter on one I already installed. Thanks..
