Yes, but now you are back to the situation of having two trains exiting along the straight through paths. The two legs of the wye are different polarities.

Yes, the DB150 has a reverser built in, but you still need to have the track isolation points designed such that you never have two trains crossing from one section to the other with different polarities.

I guess I should have the District split outside of the station wye/stub area.I thought it might be a solution ,using the DB150 but I guess   not

I don't recall seeing your full layout, but what is driving you to want multiple boosters? I can understand power districts, protected by circuit breakers, but will (could) you really have enough draw on the layout to overburden a DCS-100? Would be interested to see what you are planning in total.

Yes, I run 24 decoder equipped engines and have 60 lighted passenger cars at any one time in addition to having
a dozen engines with sound and 60 other engines on the layout at a time

This is a smaller layout then my previous layout so 16 engines with the lighted passenger fleet might be the max draw.
The engines with decoders still draw even if they are waiting to be run. I have around 75 of those. when I run sound equipped engines they will draw down alot

As you plan your system, I think you should separate the power distribution and polarity switching functions from each other.  The DB-150 is primarily intended for additional power, the fact that it can also function as an auto-reverser may or may not be helpful in your situation.  When planning power distribution, you should try to divide your layout into two districts that will each hold roughly half of your power-consuming trains at any given time.   If it happens that your stub terminal qualifies to be its own power district, then it might make sense to feed it with the DB-150, and simultaneously use it as an auto-reverser.  But given that there are only 6 tracks in the terminal, it's hard for me to imagine that you'll draw anywhere near the 5 amps that the DB-150 can deliver, even if it's loaded up with lit trains.

Regardless of what reverser you use, you'll still have to wire the terminal feeders according to the above diagram.
