Factorio Train Signals – Absolute Beginner Tutorial
6I love trains. Not just in Factorio—I love them everywhere. There's something magical about watching them glide along the tracks, perfectly timed, efficiently moving cargo or passengers. And in Factorio, trains are one of the most satisfying mechanics to master.
But signals? Oh, signals threw me for a loop when I first started. Controlling train traffic, avoiding jams, making sure everything ran smoothly—it was overwhelming. After countless hours of trial and error, I finally cracked the code, and now I want to help you do the same.
In this video, I’ll show you the absolute basics of train signals, breaking it down so you can get your rail system running like clockwork. Whether you're just starting or still struggling, I hope this guide saves you the frustration I went through.
This tutorial was done in vanilla Factorio (no DLC or mods) version 2.x.
