How a hell I can solve this:

Seems nothing work right.
Long rail, so I want a 2 or more train, but how they can pass?
Sorry, English is not my first language.
You need no choosing-signal befor a crossing. Stations have a build-in-signal.
You have to make both sides to one-way tracks. The north-track in one direction, the south-track in the other direction.
To build one-way-signals you have to click with the signal-tool on the signal too. 2 or 3 times.
Edit: A choosing signal is to choos a free station. Set it before a station with more than one plattform.
You need exactly two signals, no more. They will convert the two side tracks to one-way.

Build these as normal signals, then click with their builder tool again to change direction. You can cycle through bidirectional, right, left.
A signal in direction > faces the open end of parenthesis (here left side) and allows trains to go only from left to right.
A little too simply. :)
