I think the amount of track can stays roughly the same if you use sidings or stackers, because the number necessary to "hold" the amount train would be similar. It could be pictured as where on the network they are located. It would probably require less rails to use stackers, because all...

You could have a station with a limit of 3 or 5 with enough room to "host" 3 or 5 trains. "Capping" the limit to the available "parking" place. Even adding dedicated waiting space for one train at each station at least doubles the amount of track it requires, and makes...

One of the attachment has disappeared Ah, whoops! Fixed, thanks. a dummy train stop, "adds" some distance to a lane for the pathfinding purpose I did consider this, but a dummy stop adds a penalty of 2000, which is much more than the penalty for a train waiting at a signal (starts at 100)...

The train pathfinding system in Factorio has confused me for quite some time, and I think I've figured out why: sidings don't work the way I'd expect them to (and it doesn't seem to be possible to make them work in quite the way I want, though I've found a method that comes close). Take this image f...
