Wiring a double track pass DCC
Posted by transit on Saturday, May 27, 2023 9:09 AM

Laying a double track pass at entrance to a yard. Built on workbench, then installed on layout. No other track added. Using Peco insulfrog #6 and Peco track. With leaders on all free-ends, left and right, trains run fine on parallel tracks. When I flip any switch, I get a short. I tried positioning leader wires at junction/between two switches, but same resulting short. Have I created a return loop situation, or, otherwise, why am I getting the short when a switch is flipped? Thank you very much for your ideas/help!

Hello All,

Welcome to the forums!

Your first few posts will be moderated so there will be a delay in viewing them.

The description of your track arrangement is confusing...

Laying a double track pass at entrance to a yard.

Are you describing a passing siding?

A single crossover?

Or, a double slip crossover?

As always a track diagram- -no matter how simple- -always helps.

PECO Insulfrog turnouts are power routing- -whichever way the points are thrown that's the way the power (signal) flows.

If you are attempting a double-slip crossover, gapping and adding feeders to the "X" section created in the middle might be necessary.

Without knowing the exact track arrangement leaves the great folks on these forums speculating on the numerous possible solutions.

Hope this helps.

Welcome to the forum.  Your posts will get hung up by moderation for a while.

I think what we call feeders, you are calling leaders.  "Double Pass Track" is not a term I have seen in the forum.  Double main line, I know.  How this track interacts with your yard is not clear, at least to me.

This Forum has unique rules for attaching a picture.  You can't do it, you can only attach a link to your picture posted on the internet, where the rest of us don't need a password to see it. 

My advice is to read this thread on how to post pics, go to Imgur.com and get a free account.  Make a sketch of the problem track, with feeder location, take a picture of it, upload it to Imgur and then copy the BB-Link and post it directly in your text, without the photo icon.  Imgbb.com is another free site.

Even if you draw a pic of the track on a piece of paper, and/or take a photo with your phone, and post it, you will likely get a speedy answer

Is it possible that you have the phasing opposite on the two parallel tracks.?

Looking from one end, Are the two left rails of the same phase and the two right rails the same phase.
If not, all will work well until the turnouts are thrown.

Hi there. Sounds like you inverted your wires on one of your parallel  tracks, if I understand your description properly. Double-check your wiring.

I am guessing / hoping that you have found the problem & have resolved the issue?

Unfortunately, this happens much too often on this forum. A newbie starts a thread with a question. Replies begin to accumulate. The OP remains silent. At least acknowledge all of the replies even if you don't have time to follow up on the incoming suggestions and advice. Sad.

Maybe they had a brain fart & are too embarrased to admit it...lol

It's also possible that someone unfamiliar with the forum rules will post, not see their post appear because of moderation, and go elsewhere.
