Thanks Crandel and Robert.

Could you please edit my layout pic, and show me exactly where to place the gaps? (I'm braindead right now)

I appreciate all the help you guys!!

Thanks,

Michael

Michael,

Did you look at the 3 diagrams that I provided links to?

These diagrams illustrate your problem and show where to place the insulated gaps to create a reversing section and solve your problem.

Thanks Rich, yes I saw the diagrams. It's hard for me to visualize with my layout.

But, here is where I think they should go. Starting at the top end of the wye down through the two switches, through the mountain tunnel and back up the other side. Then wire everything in that section to the reverser outputs.

Like this ??? (gaps marked in red)

Thanks,

Michael

I think I was missing a set of gaps, added 3rd gaps to other leg of the wye.

Is this it?

You're still missin a set of gaps. You need another set on the track right next to the last set you added.

One more set of gaps. Make sure you connect the feeders from all of the rail within the gaps to the AR1.

Michael,

CSX and mfm37 are right.  If you try to complete your reversing section by creating gaps on the other side of your mountain tunnel, you have effectively incorporated that second right hand turnout, the one below the right hand turnout leading to your wye, into your reversing section.  So, you must create a set of rail gaps somewhere beyond the diverging rails of that second right hand turnout as mfm37 has illustrated in your layout diagram.  That way, you have completely isolated your reversing section.  Without the final set of rail gaps, when your auto-reverser is activated by a reverse polarity, you will suddenly have reversed the polarity of the rails leading off of the diverging portion of that second right hand turnout, causing a short.

Capice?

I just had an aha moment!! OK, I fully understand now. I was close! Tonight I will give this a shot, wish me luck.

Question: What if I have another train in the passing siding, on the left side, since I am extending the reversing section up through there. Will that work ok?

Thanks again to everybody who helped me out with this, I really appreciate that!

Michael,

Actually, I wondered about that, and I am not sure that I know the answer.  It may be that a train entering or leaving the siding at the same time that another train is entering or leaving the reversing section at another point may cause a short.  If I were wiring that reversing section, I would probably move the gaps down on the left side of your diagram just below the turnout leading to the passing siding so that the passing siding is not part of the reversing section.

Yes, that will work; however, what you can not do is have a train crossing the insulated gaps on either of the tracks at that location while another train is crossing the gaps on the left leg of the wye. Depending on how you plan on operating and whether or not the reversing section would still be long enough, you might be better off moving the gaps on the left hand side down to just below the turnout for that siding. It just looks to me like you would have less likely hood of trying to cross both sets of gaps at the same time with that arrangement.

You also cannot cross the gaps on the left leg of the wye at the same time that you cross the either set of gaps on the right leg of the wye. For that reason, I would move all three of those sets of gaps as close to the two turnouts on the bottom of the wye as possible.

OK just so we are all in agreement here, the gaps will go as follows...

Michael,

Is it possible to move the gaps on the left side of your layout diagram, so that the turnout is gapped before the passing siding rather than your proposed arrangement where both tracks are gapped at the other end of the turnout?   In other words, gap the two rails at the bottom of the turnout rather than the four rails at the top or upper portion of the turnout.  That way the entire passing siding is outside of the reversing section.   That just seems like a cleaner arrangement.

Rich,

Yes I do agree, however, the moutain tunnel portal is covering the front part of that switch.

Ahh, then no can do.  Then, just do it the way that you most recently diagrammed it.

I have good news. IT REALLY WORKS THIS TIME!!!!!!!!

I finally can run my passenger trains through the wye now without shorting out!! It's all good now, the sun is shining, the birds are chirping.

Rich, Crandel, Robert, and everyone else in this thread, I really really appreciate all the help you guys have giving me.

I can't thank you guys enough, I'm buying everyone BEERS!!!!!!!

My own hand in your success is next to nil, but I am still happy to read posts from frustrated users who come back and report that they have their problem solved. Smile  It is good for the forum, and great feedback for those who stick with the sometimes increasingly despondent or downright angry poster who has the problem...we have some very patient and talented people here.

Thanks Crandell, you helped quite a bit also. I have to admit, I was a little angry and frustrated and ready to give up this idea, and really the solution was not that hard to implement. I realize that the trackwork I ripped out was probably for nothing, but heh I don't care now that it's all good.

Sincerely the happy camper,

Michael
