Well ok, that would have been nice to see from the start. You have lots of reverse loop issues.
In my opinion the whole layout needs to be looked at at once to provide the best solution.
More later, when I have time…

Yep, I agree. 
Interesting!
So you have a turntable on each deck, eh?
It appears that you have three points of opposite polarity on the upper deck where track folds back onto itself. Depending on how you wired the upper deck (red over black or black over red), will determine where you need to add gaps to isolate the reversing section(s).
Where are your gaps on the upper deck?
Just out of curiosity, is that crossover directly below the helix a crossing or a slip? If that piece of track is another Atlas “crossover”, it is a crossing like the one on the lower deck because Atlas does not make slips in HO or N scale.
Rich
Rich,
It is a slip
I will send you existing gaps soon on the upper deck.
2 turntables, Yes it is conceptually designed for city to city layout thus the 2 turntables (both Walther’s )

Sheldon,
Would appreciate it you could.
Thanks
What brand is the slip?
I went a took a look at your website. Very nice looking layout, certainly different from what we are accustomed to see with the typical North American layout.
The plot thickens, so to speak, as you give us more information and provide more track diagrams.
A few questions.
Does everything perform well on the upper deck?
Where exactly on the lower deck are you experiencing a short?
That “crossover” on the lower deck is a crossing, not a slip, correct?
Rich
Rich,
Pleased see attached for gaps and a few changes the change is highlighted
As to does it work a loaded question to cut a long story short I had a guy/company build this for me he walked away without a say so leaving this unfinished (& a lot of my $$$) and a lot of mess and very very shoddy work;( you should see the wiring under) which I am slowly trying to fix so yes parts work but i will look at the upper deck after i try fix lower deck.

On loop on left side going to/from the main line going to yard and lower Helix

Yes it is a crossover
I drew a diagram of your upper deck marked points A through E for further comment.
A, B and C are the three points of opposite polarity where red meets black and black meets red. You need gaps in the rails at these three points.
You already have gaps at A, so you just need to add gaps in the rails at B and move your gaps from D to C. Your gaps at E are OK.
As a result, you will create a reversing section of all the track inside points A, B, C, E.

Rich,
The wiring is Black on the outer rail of the outer loop i.e. rail nearest to walls are black (the other rail is red)
Also can you please look at the entire layout including helix from lower deck to upper for auto reverse placement.
if Helix from lower deck has outside black it will integrate with eh upper deck without any issues (I think( Your schematic for lower deck I think shows red on outer rail going up the Helix)
Thanks,
Vik
Vik, I am going to have to step back and let others try to help you because I cannot make sense of your wiring protocol. The best thing that you could do for yourself is to map out how the rails are wired (i.e., black/red) and gapped on both the Upper Deck and the Lower Deck.
You say that my schematic shows red on the outer rail going up the Helix. That is because that is what you showed on your schematic, as shown below:
So, I naturally presumed that the upper deck was wired Red on the outer rail.
The following two schematics show the wiring of both decks based on my understanding from what you have been saying and agreeing to. So, your best bet is to correct my drawings with drawings of your own.
I can tell you this. From everything that I can gather, right or wrong, you have 2 points of opposite polarity on the lower deck and 3 points of opposite polarity on the upper deck. No matter which way you wire your tracks (red over black or black over red), you are going to need one reverser on each deck, possibly two on the upper deck.

Hi Rich,
Attached are my wiring indicating Colors
- There are 2 power zones on each deck. The main loop on both are Black outside Red inside. 2) 2) The 2nd zone is Orange & Brown, as in the drawing
- Helix is black on the outer rail and red on the inner rail
Let me know
if anything is not clear
I appreciate your help and owe you tons of thanks.
Regards,
Vik
Where are the gaps located on each deck?
Rich
I think that we are at a standstill until we see where you have placed gaps on this layout.
But one thing stands out.
On your Upper Deck drawing, that connection at the top center is a dead short because even though you show black to black and red to red, that is a dead short the way your diagram is drawn.
Rich
Also, the way the slip on the upper deck is wired is suspect. Anxious to see if it is gapped.
The lower deck has two points of opposite polarity so, again, the number and location of gaps is critical to prevent s short.
