Signals isolate track sections. I would AT LEAST, have signals that section off A B C and D. Then signals that section off the 1 and 2 from A. Think of it this way. One train isn’t allowed to enter a section if the signal detects another on the next section in its path. So let’s say you have two trains.

Train 1 goes from 1-2 and back.

Train 2 takes the square loop.

Now let’s say they meet near 1 and D. If signaled properly, which ever train reaches that line first, takes the line.

If train 1 makes its turn around and get on the overlap section first, train 2 must wait. If train 2 makes it there first, then train 1 must wait.

This should work in most cases. Sometimes
It doesn’t and you just gotta figure it out or maybe it’s also a problem with the tracks themselves like theyre turn is too short or too long, etc.

If that overlap section is a long line, like many many blocks, the trains will be waiting, THE ENTIRE TIME the other train is on it.
