I need help with this train system.

Hey guys, this is the first time i am using this amount of trains. I am trying to get all mining bases to one small island. I have been dealing with this around 6 hours. I just couldn't do it and give up. There are path errors and signaling problems everywhere.
I just upluoad the file. I would get screenshots but i don't think i can get every single train line so it totaly depends on you.

A good way to find "no path" errors is to open the train gui and then trying to send it to a temporary location. just hold ctrl while in the gui and move the mouse along the track. you will see where your train can go or cant go.

in case of your uranium train you have a reversed signal near the stone patch:
