how is the wiring done on a wye turnout ? What is needed?
Not very good with wiring and electrical aps.
Are you asking about a single turnout or a wye that can turn a train around and head back the same direction? If it a single turnout then treat it like a regular turnout.

The only difference between a true two-way (wye) turnout and a regular or curved one is that the two routes diverge, and they almost always do it mostly symmetrically. That is, if you continue an imaginary axis up the middle of the stem, or entry track, and go on through the frog point and beyond, each exit should have its track center very close to the same distance from the imaginary axis as the other exit route’s track center. But they are identical wiring and routing-wise. They can even be non-routing or routing, live or dead frog, just like all their various cousins. Slip and lapped turnouts need a bit more brain power…and wiring.

Yes, I am asking about a wye that can turn a train around and go back on the same track it came in on.
Thanks

First let me say I’m not an expert on solving electrical problems but I do have two reversing loops.
I use a PS/AR on each of them from Tony’s Trains http://www.tonystrains.com/index.html
User Manual for Power Shield Auto Reverser PS/AR | Tech News at Tony’s Train Exchange.
Tony’s Intelligent Reverser unit provides auto-reversing for return loops, reversing Y’s and turntables. In addition, it provides overcurrent protection, which sectionalizes the controlled track area and prevents shutting down other parts of your layout when the track is shorted.
Instruction on wiring comes with it and of course the forum will guide you also.
You will need to isolate the loop by having gaps on each divergent route from the wye or use insulated rail joiners. Also keep in mind the the train length has to fit in the loop.
In addition consider getting a PS one circuit breaker to place between your power supply and the bus. This is to protect the power supply and the DCC controler from shorts out side the loop.
Good luck and
Happy Railroading

Then, just gap the rails on the two legs of the wye track that lead into and out of the reversing loop to isolate the reversing section.

Please disregard what I wrote.
Rereading your post and others has made me question whether you have a true reversing loop or just a loop. A true reversing loop would be indicated if you traced the outside rail for example and when you completed the loop it met the inside rail. Otherwise it would just be
The OP says that he is asking about a wye that can turn a train around and go back on the same track it came in on. So, it is a reversing loop. He needs to gap both rails on each of the two diverging legs of the wye track.
Rich
Do not assume the OP is running DCC. The PSX will not work on a DC layout.
A double throw double pole toggle will be needed for a DC layout. Gaping of the rails is the same. You can totally isolate one leg of the wye or both legs. If you isolate both legs then that leaves room in the block for switching an industry or something else without constantly flipping polarity. There are resources on the web that explains it in depth. Just google reverse loop wiring schematics. Here is one from the NMRA. http://www.nmra.org/beginner/wiring.html
