I play on a server with a friend and I need help with trains. I have 2 railways crossing blue is a train that comes from the north and the 2 red arrows are trains that come from the east and go west, then come back from the west and cross to the east on the lower track. I need to figure out how to get them to intersect and not hit each other using railway signals and signal chains. I can't after hours of fiddling so I am asking for help. Can you help? (images would be best)

I always recommend the tutorial in this reddit post. https://www.reddit.com/r/factorio/comme ... ts_23_and/

If you can't access reddit or imgur, a pdf version is at https://drive.google.com/file/d/0B22HAM ... wzYjA/view .

assuming that the red train returns somewhere else

if the red train is bidirectional also place the star shaped signals
you were not clear about that.

anyway its always good to understand what you're doing
check the tutorials, its not rocket science.

CS for chain signals
S for normal signals

If the red train is longer than LCC then the middle S signal has to become a chain signal.

Sure, currently an LCC train barely fits between the two crossings, so it works. May I say to my defense that the schematic arrows in the original post made me think the author would be using short trains?

Totally. Just wanted to mention it so the next post isn't "Why does my train get stuck on the crossing?".

OK.
