I enable Safety for all the trains related but they still target the rails and destroy them one by one? Is there a way to fix this?

You may not have enabled the "Safety: Enable building safety" setting. Without it, the other "safety" settings are ignored.
.

I it is in map settings, then Im pretty sure I enabled them all. I also have ERM and krastorio 2 enable as well. They even launch attack specifically into rails as well. Do you have discord channel or anything, I can send you the settings or anything you want to check it out

I don't have a Discord channel
I think it would be best to send me a save at the moment the biters attack the rails

Okay will do now

Im uploading my mods folder to google drive. If you require it, Im sending it

I downloaded your save and looked at it.
Everything is exactly as I said above. You didn't enable the setting "Safety: Enable building safety".
This setting is the very first among other "safety" settings.

Also, the first time you turn it on, the biters will continue to attack the rails, but the destroyed objects will automatically be replaced by invulnerable ones. New rails will be invulnerable immediately

I'm curious, why do they attack rails and power poles? They didn't attack them in vanilla. Is there any way to disable this behaviour change entirely?
