can somebody look at the photo and say what am i doing wrong?
I have 2 trains,2 pick up,2 unload,train stations.
just need to bypass one train when unloading.

The easiest rule of thumb to work with is CHAIN signals before any intersection, RAIL signals after. See if that works (it looks as though all of your signals are Rail Signals in the picture)

Looking more closely, however, the problem appears to be in the lower picture, where a train is blocking the station exit? This is because the signal it's at is on red, but we can't see far enough ahead to say why. Drop another rail signal about 1/2 way to the following junction (splitting that part of the track into 2 blocks) and see if that helps?

EDIT: Can't tell for sure, but it looks as though the intersection just off the left side of the picture isn't signalled at all. If that's the case, that will be the root cause of your issue

Help me a lot ... after that just play with the new what you have learned.
And then you will be also a Pro Train er
