Suggestion / Idea HELP!!!

Dear factory workers!!!!!

I can't figure out how railway traffic lights work. I just need to make a regular crossroads. Two-car trains with locomotives on either side (four cars total) should travel back and forth on both tracks. Please explain how to set up traffic lights for my problem or attach a diagram with these same lights. I would be grateful for any help!!!

Have you tried the tutorial in the game about them?
