So treat it like one reverse loop,  with only one auto reverser.  I am also understanding that your saying gaping only one of switches outside the loop and not both switches outside the loop.   By the way, I am using Digitrax DCS100 system and if that is the case I will get an AR1, and not borrow a district  from my PM42.   I also have a BD150 that I am using as a booster, so I could also use the internal auto reverser in that.  My main concern was if I needed 2 auto reversers for this and if what I drew was possible.

Thanks  for your help

Those two turnouts at the upper right portion of the circle would be one way to do it by gapping the end rails of those two turnouts, assuming that gives you enough length.  But there are other ways to do this as well.

For example, you could make the entire circle a reversing section by gapping the rails of those four turnouts just outside the circle.

Ed,

I guess my computer didn't like your scan so it dumped it into Spam.  Sorry about that.

Attached is your drawing.  You can certainly use one auto-reverser to isolate a single reversing section of track.   It is all in the wiring as to where you create the reversing section and how long you need it to be.

richhotrain,

I sent you a email last night and just now again.  You might want to check your spam.  My email address is vieredy@cox.net if you want to send me an email I can just reply to if needed.  Thanks again for all your help.

Everyone,

richhotrain is helping me out by sending a diagram.  I appreciate everyone's help thus far.  Thanks much

I sent you a PM with my email address.  Still waiting for you to email the track diagram.

I have a picture scanned on my computer but still trying to figure out how to attach it. 

I have one single loop with 4 switches on the loop for a total of 4 enters and exits within the loop.  2 of the switches go to another (5th) switch outside the loop for north bound trains going into the loop and the other 2 switches go to another (6th) switch outside the loop for south bound trains going into the loop.

 

Its like taking 2 seperate reverse loops going opposite directions and combining the 2 into one loop (sharing one single loop)

I think I understand what you are talking about without a diagram.  Insulate both rails on each leg of turnout #5 and turnout #6, and have everything between those turnouts as one block connected to the output of the auto-reverser.

You cannot "attach" it on this forum.

You have to post it to a third party server like Photobucket and then link it to this thread.

Can you email the diagram to one of us and we can post it for you?

If it's a single loop, you should be able to do it with a single DCC autoreverser.

But, they devil is in the details, and one of those is the track configuration and how the turnouts are located.  For that, I'll ROAR with the Lion and suggest a diagram.  We're not particular or fussy.  Draw it with a pencil, scan it or take a picture, put it up on Photobucket or wherever and post it.

The key to getting it right is where you make the breaks in the track to isolate the loop.

A picture or diagram would help. LIONS do not do DCC, but if it will do DC correctly then it should do DCC correctly too.

HO layout (DDC) Reverse loop help
Posted by Vieredy on Friday, May 24, 2013 10:56 AM

I would like to know if it is possible to build 1 reverse loop that could handle tracks entering the loop from 2 opposite directions (one train would be in loop at a time of course) and then return back.  My example would be a north bound track entering the loop and returning back going south and also a south bound track entering the same loop and returning back going north.  I have laid out the track and 6 switches to do this, however Can this be done electrically and what components would be required.  Thanks for any help
