Please for the love of God, can you explain to me how to set up a simple train crossing? All I want is a simple + shape.

There's two different tracks that need to cross, but who don't end up in the same station. One train is going north/south, the other west/east, and they both loop around at both ends so they go up and down the same track. So all I want to do is make sure they don't ram eachother at the intersection. But for the life of me, I've tried so many things and they still all seem to fail.

Plenty of tutorials out there but they immediately jump to things that seem even more complex and for which I have no need at the moment. Especially if I can't figure out this one simple thing. Can you guys explain to me, step by step, what to place, and where to place it?

The basic thing I remember and use is this -- When tracks cross: Before the crossing, use a conditional signal; After the crossing use a standard rail signal.

If you cross two sets of tracks -- it would be conditional, crossing, conditional, crossing, standard rail signal.

Hopefully I understand the description of your setup properly. Depending on whether you're running single track or one lane for each direction, this is how you'd let two (independent) tracks cross each other: The basic premise is that a chain signal will NOT let a train proceed until the following regular signal is clear. Thus, you want them at the beginning/middle of intersections, to keep a train from entering until it's certain that there's a pathway out on the far side.

or for you left side drive folks like myself. (makes networking signals neater)

This tutorial (I linked right where crossings are described) is really good and aimed at beginners with trains. Every time i have to do anything more complicated than a single train track, I have to get back and watchit.
Yes, I'm a forever noob in trains, although hundreds hours of gameplay
https://youtu.be/3ZiL7_vfJtQ?t=1080 this is a give on a 2x2 crossing. The only thing is it's diagonal and not north/south/east/west.

I have also found this to be a really good guide from complete rail noobishness to reasonably advanced network design principles

Single lane intersection

Two lane intersection

Thanks to everyone for the tips! The single lane intersection above is what I was looking for. I managed to get it to work now, thanks!
