signals is a mod that allows us very interesting functions when creating and using complex railway systems in Minecraft. The mod allows us to create objects with which we can create automatic tracking systems, with traffic lights and track changes.

There’s a block that works like a traffic light in real life, allowing carts to pass or not depending on whether it’s green or red. We can also create a block that allows us to create lane change systems, create level crossings in Minecraft, making some cars go in one direction and others in other directions.

The whole railway system that we create with this mod can be managed from a controller, as we can see in the image below.
