#Factorio rail signal tutorial how to#
It is pretty simple if it was one direction from A - D to B-c, but i cant figure out how to signal for both direction. Problem is i am trying to avoid collision at intersection x. So one train loops between A and D while 2nd loops between B and c. If single direction is the way to go then i will make changes but if intersections in 2 way is possible i could use some help. Most of them tell to avoid using a 2 way track. Originally posted by mOj:Hi i am fairly new to game and learned most from tutorials and online videos. You can technically make 2-ways work for a while but it will rapidly become problematic in term of throughput as you add more trains. In that case, put a standard rail signal at the entrance for each side (after the branching) and a chain signal before they merge again.

This means that there should be no standard rail signals except for the incoming side right before a train stop (at least a train length between the signal and the train stop).ĥ/ If you want to "break" the chain signals to allow more than one train at a time to travel, you need a short "exchanger" where 2 1-way rails replace the 2-ways portion for at least a full train length. When you use 2-ways rails, you need to add a few important rules:Ĥ/ All parts that are 2-ways except right around train stops should be treated exactly like an intersection. A set of two 1-way rails is definitely the way to go when you start increasing the amount of trains you are using.īasically, there is a set of "rules" that allow you to easily do signals for those:ġ/ In long stretches without intersections, have standard rail signals at regular intervals (to allow multiple trains to follow each others since they are going in the same direction).Ģ/ Right before intersections (for the incoming rails) and through the whole intersection, use chain signals.ģ/ Right after an intersection (for the outgoing rails), use standard rail signals.ģb/ If the next intersection is too close to fit a whole train between the two intersections, treat both intersections as a single one (do not put standard rail signals in between but chain signals instead).
