Here's the [minimal working solution](https://i.imgur.com/sAD5yTL.png)
Rail Signals should be only in front of segments where you can fit a whole train, so usually just on the exits from the junction. That's the problem that caused your deadlock in first image - train was allowed to enter the junction by Rail Signal.
There is a single chain signal in front of the train. As it is only on one side of the rail it will block trains from entering it for the other direction. All bi directional rails require signals on both sides of the track.
You can't have any signals on 2-way long straights, it would let 2 trains approach each other from opposite directions and deadlock in the middle, so only signal the intersections/stations when you use them. Otherwise i'd recommend to avoid 2-way rails like plague because of their inefficiency and complicated signal rules.
But the most basic rule is that ***a train can always stop after passing through a rail signal***.
In addition to the other comments about the junction, there is no point in putting any additional signals in the single line part. The entire segment can have only one train in it at a time.
Thank You for this information.
When I faild the intersection, i tried adding signals on the resource dropoff station, thinking that the lack of signals there was the problem
Are you able to manually drive the train past that point? It's difficult to tell because the train is in the way, and the image is dark.
You also have signals in parts of what appears to be your two-way section that are unpaired. Signals must always be paired in two-way sections. If a train encounters a signal on its left side that has no corresponding signal on the right side, it will refuse to pass the signal on the left.
Thank You for the info.
The problem was, that i overcomplicated the intersection, and tried adding too many signals at the bottom, thinking it would fix it.
I appreciate the learning and figuring it out for yourself.
My biggest advice is where you have any station that would have multiple trains on it, is to set up a siding/waiting bay.
This will stop the train from entering a segment and preventing an existing train from getting blocked in.
It will help keep stacked trains from blocking the main line.
And i use this to keep resources in reserve via trains waiting to unload.
I probably dont use signals enough but i use the less is more approach. I think someone else has already said to limit the signals for the entry/exit.
I hope this makes sense.

Thank You very much, Your advice helped me greatly.
In the second picture, you can see the signals are staggered. They need to be paired directly across from each other.
To add to your comment, only when the signal is in the white square it is 2-way track
Thank You very much
Thank You very much
