The type is used to determine the refueling station for Autorefuel. In this case: 3 wagons (C) with a locomotive (L) at the front and end.
#FACTORIO TRAIN SIGNALS FREE#
Worse because of slow stopping/acceleration, once you have trains start stopping frequently a junction slows to a crawl, (and the path finder doesn't like immediately switching to a free route when already stopped on a red chain signal causing occasional problems for multiple line solutions).īut simply swapping the north/south lines solves that scenario it because those busy routes wont cross.- Train: Choumiko (L-CCC-L): The name and type of the train. More spacing wont really help because you still merge in between. if the 2 trains you show stuck are busy routes, the crossing right turns and block each other and also block the opposite left turn so will cause heavy traffic. Correct signals fix jams but still have terrible throughput if its the wrong layout, and just "adding lines" can result in a mess with still lots of delays.Į.g. Proper spacing is a much better alternative, assuming there is room for it.Ī lot of it comes down to planning for the busy routes. True, just be aware that the only signalling, at least as far a I know, that will avoid this deadlock is the "entire intersection is one block" style which kills throughput. To make the small circle 4 way intersection somewhat work, you need trains smaller than signal blocks and need at least 3 signals in the circle, so the train can't block on it's own tail and have it surrounded by chain signals so only one train can enter at once.īTW: It uses 4 exists, but that only work in the real world, avoid at all cost intersection in factorio with more than 3 exits.ĭeadly-Bagel wrote:Signalled correctly this will not happen.
It needs to be 10 times the size and it needs some magic, I'm not sure can be done in circuitry, for the concept of a roundabout to be theoretically achievable. It blocks other traffic from merging into the circle, because it is too small and because of how it's signaled. It's too small so train blocks on it's own tail. You didn't make a roundabout, you made a small circle intersection design that is very flawed. So-called "modern" roundabouts require entering traffic to give way to traffic already in the circle and Roundabout problem factorio.jpg (136.79 KiB) Viewed 27649 timesĪ roundabout is a type of circular intersection or junction in which road traffic flows almost continuously in one direction around a central island. Does anybody know why or has a solution? Preferably without changing the design too much if possible. The one to the top is hidden by the train.ĩ9.99% of the times the design works, just once every few hours a train gets stuck. There are 4 rail chain signals: top, bottom, left and right. So I do not think that a problem lies there. The bottom track is straight for some time with normal signals spaced evenly. Instead the train stays in the roundabout and gets stuck because it's too long to fit completely. In this game I have no seen a strange occurence:Ī train is coming from the right (blue arrow) into the roundabout and is supposed to leave the roundabout at the bottom exit (red arrow). They worked quite well for me and I have not had a single problem in the past. In previous games I have been using roundabouts extensively. For a higher throughput for my bot-base I now use six wagons.
In the past I have either used a 1-2 or 1-4 design. In a new game I designed the network with double-headed trains with 4 wagons. I've been using trains in Factorio for some time now and have had not problems yet.
