Trains have always been a problem for me. No matter how many guides I read or tutorials I watch I just can't get it right(and they keep running me over).

So im requesting a mod that somehow allows trains to "speak" with each other to avoid collisions and deadlocks.

There was a mod for this purpose: http://www.factoriomods.com/mods/moving-block-signals

But as you can see in the forum thread:

I doubt this can be fixed due to the logic working behind the mod. It needs to iterate all trains, look for their positions and place invisible (or tiny) signal objects accordingly. And I think the main problem is that when a signal object is placed, it will cause the game to recalculate train paths. You won't notice any impact to FPS/UPS in normal gameplay, but this may slow the game down if it is done in every frame for every train.
(Don't take my words though. I am not a dev. I just think that as a programmer after observing the game behaviour.)

So, your best bet is to learn harder. Or, upload your map or an image of it and hopefully someone will solve the problem for you.
