Rich, no comment on your remarks... and with an attitude like that guess what I don't want your help!! happy model Roading! ill figure out my issue myself, I just thought I would be able to see if anyone else had better suggestions. your the main reason why these forums are a waste, im trying to give you what information I have, unfortunately I also have a job during the day, so I cant go home and scramble through my entire layout and try everything you suggested along with everything else everyone else suggested! ive given you all the information you've asked for, you seem to be arguing with everyone on here, so I want to thank everyone for your help, I will go back to basics and try a few things im sure in the end ill get it working.

Its simple, everything on the right side of those gaps i listed is on the reverse loop bus, everything to the left of those gaps is on another bus, which does not short. i also determined that there is a imeediate short and its most likely due to the polarity that crosses back on itself from tat inside sidings , but thats why i posted here cause i was not sure of myself.

there is  nothing connected to the helix side there are gaps at that first switch everything past that is wired to the reverser, i don’t think i could state that any more, there’s no complex wiring here, i wanted to put everything at that first switch to avoid the multiple trains in the loop short scenario, originally I had a gap on the far side of the upper siding and things worked, however as i mentioned in an earlier thread that was not ideal as i had situations where 2 trains hit the gap at the same time.

There forums are not a waste, everyone was trying to help. We still don't know if the turnout in question is a peco or not. Rich was not arguing with everyone, he was expressing the problem and solutions as he saw it. Lack of specific information was a contributor to the situation. And now you are going off and fix the problem probably without relaying to us what was wrong and what the fix is. Suggest if you ever use this forum again that you post that delays in responses will occur do to work schedule or whatever. good luck with your fix.

I said it was a peco, to be exact an electro frog, ,I've used the forums in the past and had very productive conversations. its not that easy when you have multiple people throwing this way, that way, ill be more than happy to give what information I can and be thankful for everyone's help, but there's no need to assume just because I don't get back right away that I am misinforming anyone, im not in front of the layout, I am planning on going over what everyone suggested as soon as i can and verify these things.

Ward, if I have overreacted and offended you, I apologize.   That was not my intent.  It is not the delay in responding that bothers me.  It is the frustration with making suggestions that seem to go unheeded and follow up questions that go unaswered when you do have time to respond.   And, I never said that the forums are a waste.  I was upset with the lack of management of this thread, such things as not stating the types of turnouts that you have installed, how the wiring inside the reverse loop is handled, etc.  All of us want to help you and most of all me.  But, we gotta have information from you to help solve your problem.  Anyway, please accept my apology because I was not trying to offend you but rather to get needed information.

No, you said all the turnouts in this area are Peco, except for one Atlas, which was followed by a question about whether or not the one where the short occurs was Peco or Atlas.  You never answered that question.  You also never definitely answered whether or not you have any other gaps besides at the ends of the reversing section, though I guess from your earlier response about  not being sure where else you would need to cut gaps it may be safe to assume you don't.

With Electrofrog turnouts, you have to have gaps on the rails coming from the frog if you have power being fed to the rails on that end of the turnout.

ok, so that short piece of track you are referring to, doesn't the reverse loop have to be able to hold your longest train in the loop? otherwise you would have part of the train in and out both sides of the loop section?
 

 

 

Who are you asking?

 

I think it is me!  I am simply saying that if you use one loco, the short length of track should be 2 locos space at least

2 locos - three locos space etc.

Regards

Trevor

I will go back to basics and try a few things im sure in the end ill get it working.

 

 
Ward, you indicated at the beginning of this thread that this has been an ongoing issue for 2 years, and I see that you have posted several threads about problems that you are experiencing with reverse loops.
 
So, permit me to make some suggestions that you should find helpful as you try to solve this problem.
 
First, draw a diagram for yourself that shows this entire area of your layout as a two-rail track diagram.  
 
Second, trace your feeder wires and color code the rails (e.g., red and blue) to reflect the polarity of the rails on each section of track.
 
Third, mark the spot where each gap is cut into the rails (or where a plastic insulated rail joiner is inserted).
 
Fourth, verify the type of turnout (e.g., Atlas, Peco Insulfrog, Peco Electrofrog) used at each location and mark it on your track diagram.  If you have cut any gaps on the turnout itself, indicate the location of those gaps.
 
Fifth, clearly identify on the track diagram where the main bus wires are begin and end, and where the separate sub-bus wires (apparently set up for the reversing section) begin and end.  Show on the track diagram which set of bus wires each set of feeder wires are connected to.
 
Sixth, show which feeder wires are connected to the input side of the auto-reverser and which feeder wires are connected to the output side of the auto-reverser.
 
If you take these six steps, you will have completely documented your track setup and make it easier for you and others to find and resolve any problems related to your reverse loop.
 
Hope this helps.

Wow!  You folks lost me about a million real miles (the 5,280-feet kind) back.  If I had a loop that was this much of a headache to figure out, I would probably fall back on the old reliable "K.I.S.S." principle (Keep It Solvably Simple), and scrap that whole thing for some other solution.  I applaud all those who tried to help, and indeed I am sure that most of the suggestions were heartfelt and genuine, not to mention knowledgeable, but I gotta side with the comment about the thread getting way out of hand; although I didn't offer any useable help, I also wouldn't have been too sure it would have any significant effect if I had, and as I read further and further into it, I'm still not sure what happened, and wether or not the problem got solved; this stuff is supposed to be , first and foremost, FUN...right? Keep on railroadin'!

you Rich, and i do truly appreciate everyone input and help, that was my intention, as I thought what better place to get some input on how this could be resolved instead of pulling track out and creating a simpler solution which in my opinion may still be an option. This section was an older section that was really put into place for staging, so I don’t run on it much, now that most of my track work is complete and electrical I wanted to obviously revisit it and correct those issues. Having a better understanding of reverse loops now, made this nightmare even more complex as I don’t think I could have designed a more headache reverse loop situation if I wanted to. I will be taking a close look at this loop again and will check very carefully the things you outlined and also some of the great advice that was given, I realize not having the entire thing laid out made it even a more complex problem that was made it frustrating difficult to assist and apologize for not having all the details, I will get that and also repost the outcome when I have it resolved. I appreciate the time and effort, with the drawings and such, I know that stuff takes time and again truly appreciate everyone’s help.

Good to hear back from you, Ward.  Keep us posted on your progress.  I know from personal experience that it can be frustrating to have to put up with an unresolved layout issue.

...Having a better understanding of reverse loops now, made this nightmare even more complex as I don’t think I could have designed a more headache reverse loop situation if I wanted to...

Actually, as far as reverse loops go, this one is really quite simple: there is only one reversing section, only one entrance at each end of the reversing section, and no concerns about a train longer than the reversing section because it is physically impossible.  The problem is NOT the reverse loop, the problem is the ungapped Peco electrofrog turnouts, which will cause problems even without a reverse loop.  If I have time, I'll do a diagram showing where you need to gap them.

thank you, Ill def take another look at that peco, Im not sure if a plastic rail joiner was used there, but i need to check on that, it sounds like it was not. I did use them near the orginal turnout on the left, after the helix and where the orginal gaps are.

So here is my diagram.  Since you never said which one is the Atlas, I just gapped them all as Electrofrogs, it won't hurt to do the same to the Atlas one.  The green gaps are the ends of the reversing section.  The green gaps have to be in both rails to completely isolate the reversing section from the main line.  All of the other gaps only have to be in the rail adjacent to the frog, the other rail can be left solid.  The blue gaps(turnouts 2, 3, and 4) also need to be there because if any one of these turnouts is aligned to a siding it will cause a short.  The yellow gaps(turnouts 5 and 6) you might could get away without, but I would not suggest it.  To not have them, the turnouts would have to be thrown together(either both to the main line or both to the siding, but never one to each) and you could not have additional feeders between the turnouts.

 

The red gaps are somewhat optional, but personally I would not go without them.  Anywhere I have a red gap, you cannot have feeders beyond that point unless you do have the gap.  That causes two issues: the track beyond the gap will be electrically dead when the turnout is thrown to the other leg and, when the turnout is thrown to that leg it's power will be fed through the turnout points(not very reliable).

 

What I would do is go ahead and cut all of the gaps other than the red ones and get that working and then go back and cut the rest.

thank you rob, ill study this one over, what happens as multiple trains go in and out of these gaps that wont trip the reverse unit will it?

What a nightmare!

If I count correctly, Ward would need to cut 24 gaps, plus all that wiring. Ugh.

I cannot help thinking that if he has not already purchased all of those Electrofrogs, he would be a lot better off with Insulfrogs or Atlas turnouts. In that event, he would only need to cut 4 gaps and a lot less wiring.

If he has already purchased the Electrofrogs, sell them on eBay and use the proceeds to buy Atlas turnouts which are half the cost of Pecos.

He could even run multiple trains in and out of that reversing section by simply extending that outer loop all of the way around and back to the main line feeding into those loops.

hello, well that's something I may consider , just bringing down the upper loop back to the original switch to the left and alleviate some issues, of course id still have the electro issues, the rest of my layout is all done with hand laid turnouts from fats tracks, I wish I would have had that option when I built this lower section.

 If you've done the cuts and added jumpers as shown on the back of the Electrofrog package, then they are electrically the same as a fast Tracks turnouts made according to their instructions.

You do not need gaps for turnout numbers 3 and 8, 9 10 11 and 12. The reverse loop wiring only needs to be in place between turnouts 2 and 4 while the rest are normal blocks. You do not need them for the turnouts that go to the dead ends such as 3 and 7 uness you are planning on running switching locos on parallel tracks. lPM me with a copy of the diagram if you would like a track circuit with switches drawn,
